The weather app
built for cyclists

Sweather scores the weather for your ride. A 1–10 cycling score for every 15-minute slot of the day, so you can time the loop, dodge the gust front, and plan the tailwind home.

Wind ruins more rides than rain.
Sweather knows that.

Generic weather apps shrug at 25 km/h wind and call it "breezy." On a road bike that's the difference between a 32 km/h average and an 18 km/h grind. Sweather weighs wind speed, gust intensity and predicted direction as the heaviest cycling factors. Not as a sidebar, as the actual core of the score.

Cycling scoring is calibrated by category. Road cycling, mountain biking, gravel and BMX each get their own factor profile. A wet trail is a dealbreaker for road; that same trail is fine for MTB. The score reflects that.

17 factors. Weighted for cycling.

💨

Wind speed & direction

Sustained wind is the heaviest factor for road cycling. Sweather shows you when it dies down, and which way it blows.

🌬️

Gusts

Gusts above 50 km/h cap the score. Cycling in crosswinds gusting 60 km/h is unsafe, not "spicy." Sweather flags it.

🌡️

Temperature & feels-like

Wind chill on a descent matters more than air temperature. The feels-like is computed for cycling speeds.

🌧️

Rain & wet roads

Cycling-specific rain weighting: light drizzle survives, heavy rain caps low, recent rain (wet roads) lingers in MTB scoring.

⚡

Thunder & lightning

Hard dealbreaker for outdoor cycling. The moment lightning enters the radar nowcast, the score collapses to 1.

☀️

UV index

Long road rides in summer get docked for high UV. Easier to find an evening window than to fry yourself at noon.

Commute-aware. Race-ready.

Save your commute as a recurring template, like "bike to work, 08:15, weekdays", and Sweather scores it every morning before you wake up. See the score on the home card, a widget, an Apple Watch complication, or as a Lock Screen Live Activity that updates in real time during your ride.

Got a gran fondo, time trial, or stage race coming up? Pin it as a Race Day and Sweather counts down with forecast-driven scoring, ensemble uncertainty bands, and a 5-year history of conditions on that date.

Common questions about cycling weather

What is the best weather app for cycling?
For sport-specific scoring, Sweather. Generic weather apps tell you the temperature; Sweather tells you whether to ride. Wind speed, gusts, headwind direction, road precipitation and UV are weighted heavily for cycling because they have the biggest effect on ride enjoyment and safety.
How much wind is too much for cycling?
Sustained wind above 30 km/h makes road cycling unpleasant. Gusts above 50 km/h are flagged as a dealbreaker by Sweather. The 17-factor scoring engine takes both into account, plus the predicted direction so you can plan a tailwind home.
Does Sweather work for mountain biking?
Yes. Sweather has separate profiles for road cycling, mountain biking and gravel. MTB tolerates wind better (sheltered trails) but weighs recent rainfall heavily, because that's what changes trail conditions. Each sport gets its own score.
Can I sync Sweather with Strava?
Yes. Connect Strava (read-only, free) and Sweather picks up your regular riding times, your favourite routes, and tunes the cycling score to how you actually perform in different conditions. All processing happens on-device, no data is shared.

Ride when the weather agrees.
