Berkeley Marina Windsurfing Launch
Kite days peak in June at 48 %.
A kite day has at least 3 hours of 12 to 35 knots (gusts up to 45) between 10:00 and 19:00, in daylight. Percentages are the share of such days in each month, counted over 9 years.
- Prime 60 % and more
- Good 40 to 59 %
- Possible 20 to 39 %
- Off under 20 %
- No data hatched
- Ringed: this month
Prime also needs a good month in at least 7 of the 9 years, so one freak year cannot make a month Prime. A month with 60 %+ but fewer good years shows as Good.

Good years are not shown here: this spot has no complete per year values, because the two models drift apart over the years. x in 10 reads: of all 10 day trips that started in that month between 2017 and 2025, x in 10 got at least 5 kite days. We cap the figure at 9 in 10 because wind is never a promise. Best hours: the hours from 10:00 on when the wind most often reaches 12 to 35 knots. Rain day: 1 mm or more of rain.
