Soaring weather data for free-flight pilots.
Thermal strength, cloudbase, wind, day rating, and XC corridor conditions - structured data built for the way paragliders actually plan flights. Query it directly, integrate it into an app, or build your own pre-flight briefing tool.
The data that matters for free flight.
Every field below is available at 4 km resolution, updated four times daily - across every country Convek covers. See live coverage.
Thermal Strength (wstar)
Updraft velocity in m/s. Know whether thermals are strong and consistent enough to work before you leave the house.
Soaring Height Ceiling
Glider-capped thermalling height above ground level. Will you have workable altitude on the ridge or in the valley?
Cloudbase & Cu Potential
Cloudbase AGL and MSL, cumulus potential, and overdevelopment risk. Know when to push and when to land.
Surface Conditions
Surface temperature, dewpoint, humidity, rain, and heat flux context for judging whether the day is actually building.
Corridor Sampling
POST a bearing and distance, get weather sampled along your planned XC route. Time-aware mode calculates conditions based on estimated arrival.
Day Rating
A single label summarising the overall soaring quality for the day. Poor, marginal, fair, good, or excellent - at a glance.
How paraglider pilots use Convek
Pre-flight check
Query your launch site before you leave home. Thermal strength, cloudbase, wind, and day rating give you a go/no-go signal without opening five browser tabs.
XC route planning
Use corridor sampling to query weather along your planned route. The time-aware variant adjusts conditions based on when you'll actually be at each point - not just launch conditions projected forward.
Build your own briefing tool
The free tier gives you 25 queries per day - enough to build a personal pre-flight dashboard or widget for your local club. Dev plans include commercial use.
Create a free API key, scale if you need to.
Free tier: 25 queries/day, no credit card. Pilot plan at £8/month gives you 500 queries/day. Pilot Pro at £15/month gives you 2,000/day.
