For cyclists
Can you ride today?
Wyndo is a weather decision engine, not a forecast app. It reads conditions, runs them through a deterministic engine tuned for cycling, and gives you a direct go now, leave at <time>, wait, or avoid — with the reasoning behind it.
What Wyndo considers for a ride
Wind, sustained AND gust
Cyclists feel both differently. Wyndo treats sustained wind and gust spikes as separate veto factors with cyclist-specific thresholds — so a 50 km/h gust day gets called out even if sustained wind is OK.
Dry pavement, not just dry forecast
Live NWS station precipitation observations plus recent Open-Meteo precipitation buckets. If rain fell in the last hour, Wyndo factors it in — your forecast app's green-cloud icon won't.
AQ for sustained outdoor cardio
Riding for 30+ minutes pulls a lot more air than walking. Wyndo's AQI thresholds for cycling are tighter than for driving, with explicit veto cutoffs.
Visibility minimums
Fog, blowing dust, heavy precipitation — Wyndo flags low-visibility days for cycling (caution below 1 km, hard safety veto below 100 m) since drivers can't see you and you can't see hazards.
UV + heat for long rides
A 3-hour ride in direct noon sun at UV 9+ gets a caution. Heat index (humidity-adjusted) flags the difference between dry desert heat and humid Gulf-coast heat.
Active weather alerts
Severe Thunderstorm Warnings, Flash Flood Warnings, Tornado Warnings — Wyndo treats these as automatic safety vetoes, with the alert headline surfaced in the reasoning so you can verify against NWS directly.
When Wyndo earns its keep
Commute decision in 60 seconds
Ask 'can I bike to work?' — Wyndo factors in wind safety, visibility, dry pavement, and AQ over your ride window. Get a direct go / leave-at / wait answer with the reasoning.
Long-ride window planning
Sunday gravel ride coming up? Search the best 2-hour window across the next 12 hours. Wyndo tells you when the wind, rain, and heat all line up — not just one factor in isolation.
Gust-safe vs. sustained-wind days
25 km/h sustained wind is a slog; a 50 km/h gust off an open road is a stability risk. Wyndo treats them as separate veto factors so a gusty day doesn't get downgraded just for being windy.
Wet-pavement awareness
Forecast says 20% rain, but did it just rain? Wyndo combines live NWS station precipitation observations with recent Open-Meteo precipitation buckets so the dry-ground signal reflects what actually fell, not just the forward forecast.
