About GoDay
GoDay rates the weather for the thing you want to do. Pick a spot anywhere in the world and an activity, and it turns the forecast into a score out of 10, a plain verdict and the best time of the day, right now and for the next seven days.
How the ratings work
Each of the 17 activities has its own rating. It scores the conditions that matter for that activity, weights them by how much they matter, and adds hard limits for things that spoil a day whatever else is happening, like a thunderstorm. Every colour comes with a number and a word, so the ratings read the same with any kind of colour vision. Each activity's page explains its rating in full:
- Boating
- Hiking
- Running
- Cycling
- Beach & Swim
- Footy
- Soccer
- Rugby
- Cricket
- Golf
- Tennis
- Skiing
- Motorbike
- Surfing
- Shooting
- Spa
- Sail & Kite
Where the data comes from
Forecasts, marine and air-quality data come from Open-Meteo, which draws on forecast models from national weather services. Place search uses Open-Meteo's geocoding, which is based on GeoNames. Open-Meteo's data is licensed under CC BY 4.0. The rain radar map is from RainViewer, over a map by © OpenStreetMap contributors.
What it can't tell you
GoDay rates forecasts, and forecasts can be wrong. The further ahead, the rougher: days 5 to 7 are shown dashed as a rough guess. The air-quality forecast only runs about 5 days ahead, so on days 6 and 7 Running and Cycling are rated without it. It can't see local hazards like rips, currents, closed trails or which ski lifts are running, and it isn't a safety service. Always check official warnings and local conditions, and stay within your limits. The terms of use say more.
Your privacy
GoDay has no accounts, no cookies and no ads. Your spots and settings stay in your own browser. Your browser gets forecasts and place searches straight from Open-Meteo, so the spot you pick goes to Open-Meteo, rounded to about 100 metres. The privacy page lists everything that's sent, who to, and what our server keeps.
