Is today a go day? The weather, rated for your activity

Weather apps give you numbers: 18 km/h of wind, 0.8 m waves, 22°C. GoDay turns them into one answer for the thing you actually want to do: a score out of 10, a plain verdict like "Good to go" or "Rough", and the best time of the day.

Each activity needs different weather. A 20-knot breeze is a great kitesurfing day and a no-go for a jet ski, so GoDay has 17 separate ratings, each built from the conditions that matter for that activity.

Pick a spot anywhere in the world and an activity, and you get the rating right now, the best time left today, each of the next 7 days with its best time, and every condition behind the score, rated on its own.

Every colour comes with a number and a word, so the ratings read the same with any kind of colour vision.

Questions

What does the score out of 10 mean?

9 or 10 is as good as it gets, 7 or 8 is a good day, 5 or 6 is marginal, 3 or 4 is rough, and 1 or 2 is a day to stay home. One bad condition, like a thunderstorm, holds the score down however good the rest is.

Where does the weather come from?

From Open-Meteo, which draws on forecast models from national weather services. The About page has the details.

Is GoDay a safety service?

No. GoDay rates forecasts, and forecasts can be wrong. Always check official warnings and local conditions, and stay within your limits.
