IIToday’s report
Today’s report
How it is today, in five bands
Every spot gets a report from 1 to 5 each day, based on what its sport needs: wind, waves, snow or visibility. Four words say it.
How it is today
- No conditions0–19 points
- Marginal20–39 points
- Marginal40–59 points
- Good60–79 points
- Very good80–100 points
Data: Open-Meteo.com · CC BY 4.0
Out of 100 points: each sport adds up its criteria and the total falls into one of the five bands. The 3 is called ‘Marginal’: a day with offshore wind is not a good day.
