Meteoblue paragliding: how to read and use weather forecasts for your flights
Meteoblue is a high-resolution weather forecasting tool used every day by paraglider pilots around the world. Its detailed meteogram provides hour-by-hour analysis of wind, thermals, cloud cover and atmospheric stability - all essential data for deciding whether conditions are right for flying.
In practical terms, meteoblue draws on several weather models (including the Global Forecast System, Arome and Arpège) to provide multi-day forecasts with remarkable accuracy. The tool is available free of charge via its website or app, with a premium Point+ version for paragliders who want access to even more detailed data.
But between the diagrams, the upper wind curves and the thermal indices, reading meteoblue correctly takes some doing. At Accessories, Our state-certified instructors have been consulting this tool before every flight since Gréolières, Gourdon or Roquebrune-Cap-Martin. In this guide, you'll find out how to decode each meteogram parameter, which thresholds to use to make your decision to fly, and how to complement meteoblue with other weather applications such as Météoparapente, Windy or Météociel.
Meteoblue: why this weather tool has become essential for paragliding
Meteoblue is a meteorological tool developed by the University of Basel in Switzerland. Originally designed for climate research, it has rapidly become a reference in the world of free flight thanks to the accuracy of its forecasts and the wealth of its data.
High-resolution weather models adapted to flight
What sets meteoblue apart from conventional weather bulletins is its ability to cross-reference several weather models. In particular, the tool uses the Global Forecast System (GFS) for large-scale trends, as well as Météo France's Arome and Arpège models for a finer resolution over France. This combination gives paragliders a detailed overview of atmospheric conditions, hour by hour, over several days.
Free account or Point+ subscription: what should you choose?
The free version of meteoblue gives access to basic forecasts: ground wind, temperature, precipitation and cloud cover. For pilots who want to go further, the Point+ subscription offers premium diagrams, higher resolution, detailed upper wind data and the removal of adverts. If you fly regularly, the Point+ subscription is a worthwhile investment. For first-time or occasional paragliding, the free version is more than sufficient.
Worldwide coverage, easy access
Meteoblue covers the whole world and works on both its website and its mobile application. Simply search for your flying site to obtain a complete meteogram. This accessibility makes it a benchmark tool for paragliders, whether you're flying in the Alpes-Maritimes, Haute-Savoie or Puy de Dôme.
«Weather is a pilot's first skill. Before you can even take off, you have to know how to read the sky - and tools like meteoblue help us to do that with remarkable precision.»
How to read the meteogram on meteoblue before a paragliding flight
The meteoblue meteogram is the heart of the tool. It's a summary graph that condenses all the essential meteorological information for your day's flying. Knowing how to read it correctly means knowing how to make an informed decision.
Wind on the ground and aloft: strength and direction
The diagram shows wind speed and direction at different heights. For paragliding, focus on two levels: the wind on the ground (take-off and landing conditions) and the wind at altitude (how the wing behaves in flight). An arrow indicates the direction, and the colour or thickness of the line indicates the strength of the wind. As a general rule, a steady, moderate wind is favourable. Sudden changes in direction or strength between ground and altitude indicate a risk of shear.
Cloud cover and humidity
Meteoblue displays cloud cover at several levels: low, medium and high. For paragliding, it's mainly the low and medium clouds that count. Dense cloud cover at low altitude can indicate poor visibility or a ceiling too low to fly. The humidity level completes the picture: air that is too humid limits the development of thermals and makes conditions heavier.
Precipitation and atmospheric stability
The precipitation line is simple to interpret: any rain forecast for your flight slot is a cancellation signal. Beyond the rain, look at the stability of the atmosphere. Cold air at altitude combined with a ground warmed by the sun creates instability - favourable for thermals, but potentially dangerous if it generates towering cumulus clouds or thunderstorms.
Temperature and thermal index
The meteogram shows the ground temperature and how it is changing hour by hour. This is a key indicator for anticipating the day's thermal activity. Meteoblue also provides the average speed of thermals: a valuable piece of information for pilots preparing a thermal or a cross-country flight. Positive and increasing values in the late morning indicate good convective activity.
Weather thresholds to be aware of when deciding to fly a paraglider
Reading the meteogram on meteoblue is good. Knowing the thresholds at which you can fly - or give up - is even better. Here are the benchmarks that our instructors use every day to make their decisions.
Wind speed and direction: limits to be respected
For a first paragliding experience or an open-air flight, the wind speed on the ground should not exceed 20 to 25 km/h, with gusts in the same range. Beyond that, conditions become uncomfortable for passengers and difficult for take-off. Wind direction is just as important: every flying site has its own favourable wind direction. At Gréolières, for example, a south to south-westerly wind offers the best conditions. A crosswind or tailwind on take-off is an immediate no-fly criterion.
Thermals and stability: the indicators of a good day
A good day for thermal flying is characterised by a ground that gradually warms up under partly clear skies. On meteoblue, keep an eye on the average speed of thermals: values between 1 and 3 m/s are ideal for a pleasant flight. Above 4 m/s, conditions become turbulent and should be reserved for experienced pilots. The height of the convective layer tells you how high the thermals are.
Conditions to be avoided at all costs
Some weather situations require systematic postponement. Cold air at high altitude with a strong thermal gradient can cause rapid thunderstorms. Winds above 30 km/h create dangerous mechanical turbulence. Dense, low cloud cover makes it impossible to read the terrain. And of course, any forecast of rain or thunderstorms during the flight period cancels the outing.
At Ailéments, we always check with our customers the evening before at 8pm. If the meteoblue forecasts or our other sources indicate borderline conditions, we postpone the activity without hesitation. Safety comes first.
Meteoblue, Météoparapente, Windy: which weather application should you choose for paragliding?
Meteoblue is a powerful tool, but it's not the only one. Experienced pilots systematically cross-reference several weather applications to refine their analysis of flight conditions. Here's a comparison of the tools most commonly used in paragliding.
Météoparapente: the French reference for free flight
Developed specifically for aerial sports, Météoparapente is the application most used by paragliders in France. It provides extremely detailed upper air wind forecasts, with a layered display that makes it easy to spot shear zones. Its model is calibrated to the French relief, making it particularly reliable for flying sites in the Alpes-Maritimes and the whole of the PACA region. However, its coverage is limited to France and neighbouring countries.
Windy: the most visual interactive map
Windy features an intuitive, animated interface. The map shows air flows in real time at different altitudes. It's an excellent tool for getting a quick overview of the large-scale weather situation. Windy also offers access to ECMWF, GFS and Icon models, making it a good complement to meteoblue. Its weak point: the very local data is less accurate than on Météoparapente.
Météociel and Météo France: essential supplements
Météociel provides direct access to the raw output of the Arome and Arpège models, with hour-by-hour maps of wind, precipitation and cloud cover. This is a more technical tool, appreciated by pilots who know how to interpret weather models. Météo France remains the official source of weather bulletins and alerts. Its application provides reliable local forecasts, even though it is not specifically designed for free flight.
Pioupiou beacons: real-time data in the field
Pioupiou beacons are connected weather stations installed at many flight sites in France. They transmit real-time wind strength and direction at take-off. This is the final link in the chain: after consulting the forecasts on meteoblue and Météoparapente, pilots check the actual conditions using the beacons before taking off. This real-time data is used to confirm - or invalidate - the morning's forecasts.
How our monitors use meteoblue on a daily basis from Gréolières
At Ailéments, consulting meteoblue is part of the daily routine for our state-certified instructors. With over 19 years' experience in paragliding and more than 10,000 flights completed, this habit is part of a rigorous process that guarantees the safety of every flight.
The weather routine before each flight
The evening before, our instructors consult meteoblue and Météoparapente to analyse the forecast for the following day. They check the wind strength and direction, the expected cloud cover and the risk of precipitation in the flight slot. If conditions are favourable, a confirmation text message is sent to each customer at 8pm. On the morning of the flight, a second check is carried out to confirm that the models have not changed unfavourably during the night.
Why cross-referencing several sources is essential
No weather model is perfect. The meteoblue forecasts may differ from those of Météoparapente in the same time slot, particularly in the mountains where the weather changes rapidly. Our instructors systematically cross-check at least two sources of forecasts and supplement them with data from the pioupiou beacons when they are available on the flying site. This method considerably reduces the risk of misreading the conditions.
When the weather forces a change of site
The main Ailéments site is Gréolières, in the heart of the Cheiron massif, with take-off at an altitude of 1,800 metres. This is where most of our flights take place, thanks to particularly reliable aerological conditions and an exceptional view of the Mediterranean and the Mercantour peaks.
However, certain weather conditions make it impossible to fly from Gréolières: winds too strong at altitude, low cloud cover over the massif or marked instability. In these cases, our instructors consult the forecasts for alternative sites. Gourdon offers a regular option with different conditions and a remarkable panoramic view. Roquebrune-Cap-Martin, on the coast, allows you to fly with a view of the sea in specific weather conditions. This flexibility means we can offer flights almost every day of the year, except January.
Getting started with meteoblue: practical advice for paragliders
Whether you're new to paragliding or an improving pilot, here's how to make the most of meteoblue to prepare your flights in complete safety.
Create your account and configure your favourite flight sites
The first step is to create a free meteoblue account on the website or app. Once you have logged in, save your flight sites as favourites. This gives you one-click access to detailed forecasts for each location without having to search for the site each time you visit it. If you regularly fly in the Alpes-Maritimes, Add Gréolières, Gourdon and the sites you visit.
The most common reading errors for beginners
The first mistake is to look only at the wind on the ground. Conditions on take-off may be calm, but the wind aloft may be violent - a dangerous situation that only the complete meteorogram can detect. The second mistake is to rely on a single source. Meteoblue is a remarkable tool, but local mountain forecasts should always be cross-checked with Météoparapente or the pioupiou beacons. The third mistake is to confuse the multi-day forecast with the same-day forecast. The reliability of meteoblue diminishes beyond 48 hours, especially in mountainous areas.
Supplementing forecasts with field observations
Weather applications are no substitute for observation on the ground. Before each take-off, an experienced pilot looks at the sky, observes cloud movement, checks the windsock and listens to feedback from other paragliders already in the air. It is this combination of digital data and direct observation that makes the difference.
If you're preparing for your first paragliding flight, you don't need to master all these parameters: your instructor will do it for you. On the other hand, if you're planning a paragliding course To learn to fly independently, reading the weather forecast will be one of the first skills you develop.
Meteoblue is an essential tool for any paraglider who wants to prepare his flights rigorously. Its meteogram provides detailed data on wind, thermals, cloud cover and atmospheric stability - information that allows you to make informed decisions before each outing.
But a tool, however powerful, is no substitute for experience and professional guidance. You have to learn how to read meteoblue, and it's by flying regularly with passionate instructors that you really develop this skill.

Your questions about meteoblue and paragliding weather
Is Meteoblue free for paragliding?
Yes, the free version gives access to basic forecasts: wind, temperature, precipitation and cloud cover. The Point+ subscription is not free and offers high-resolution data, premium diagrams and the removal of advertising. For regular hang-gliding enthusiasts, Point+ is a real pleasure to read.
What is the difference between meteoblue and Météoparapente?
Meteoblue covers the whole world and combines several weather models to provide comprehensive forecasts. Météoparapente specialises in hang-gliding in France and offers highly detailed wind forecasts at altitude, calibrated to the French terrain. The two are complementary: meteoblue for the big picture, Météoparapente for local detail.
How often should I consult meteoblue before a flight?
The evening before to assess the general trend, then the same morning to confirm the forecasts. Weather models are updated several times a day and forecasts can change, particularly in mountainous areas.
Can we rely solely on meteoblue when deciding to fly?
No. It is strongly recommended that you cross-check at least two forecast sources (meteoblue + Météoparapente or Windy) and check actual conditions with the pioupiou beacons or ground observation before take-off. No model can guarantee absolute accuracy in the mountains.
Does Meteoblue work for flight sites in the Alpes-Maritimes?
Yes, perfectly. meteoblue's high-precision resolution covers the whole of the PACA region, including the Gréolières, Gourdon and Roquebrune-Cap-Martin sites. The Arome and Arpège models integrated into meteoblue are particularly well suited to the relief of the Alpes-Maritimes.
How can I read the thermals on meteoblue?
The meteogram shows the average speed of the thermals and the height of the convective layer. Positive and increasing values at the end of the morning indicate good thermal activity. Between 1 and 3 m/s, conditions are pleasant for most pilots. Above 4 m/s, the air becomes turbulent.
Is Meteoblue reliable beyond 3 days?
The reliability of meteoblue is very good for 24-48 hours. Beyond 3 days, the forecasts become indicative, especially in the mountains where weather conditions change rapidly. Use the long-term forecasts to spot a trend, but base your final decision on the day's data.
Which weather application do paragliding instructors recommend?
Most professionals combine meteoblue for global forecasts and meteogram visualisation, Météoparapente for detailed wind and altitude information in France, and pioupiou beacons for real-time data at take-off. Windy and Météociel are useful additions to the toolbox, depending on your personal habits.
