Weather Nerd 2.0 forecast view for Whistler with temperature and precipitation charts
Weather Nerd 2.0 is hereWeather Nerd App Icon

Weather Nerd

Advanced, glanceable weather - anywhere on earth.

The weather app for people who actually read model data. Built for kiters, skiers, and outdoor enthusiasts who need more than a single-source forecast.

Everything a weather nerd needs

Choose your forecast model*

Pick which model powers each location: ECMWF, ICON, GFS, HRRR, NBM, Canada's GEM family, and Europe's national nests down to 1 km. Short-range models hand off to a longer-range one so the full 10 days are covered.

Compare every model*

Overlay every model's temperature, precipitation, and wind. A spread band, a median consensus line, and tap any model to isolate it.

Now on Mac

A real Mac app, not a port. Crisp native rendering, keyboard day navigation, and Settings and Radar as right-sized windows.

Snow sports mode

Freezing level charts, 10-day snow forecasts, and precipitation type breakdowns for planning your next day out.

Global radar and cloud maps*

Real-time radar tiles and satellite cloud imagery with smooth playback and caching.

Redesigned widgets

New large wind and 10-day sizes with hourly sparkbars and compass arrows, refreshed the moment the app updates.

Share the forecast

Branded share images for current conditions, any single day, or the whole 10-day outlook.

*Requires Weather Nerd Pro. From $2.99/month →

Weather Nerd is a solo project by Adrian Corscadden. Updates go out every few weeks, and most of them come from what people ask for. I read every request. If your favorite model is missing or you need something for your sport, there's a feedback link right in the app.
