Maui Weather Forecast Links
Wind
For current conditions iWindsurf has a sensor near Kanaha which gives a pretty good indications of the conditions there. They also have sensors at Kihei and Hookipa. If you’re not a member iWindsurf have a 10 day trial which gives access to all sensors.
The iWindsurf Kanaha forecast is also good for predicting the wind pattern though it seems to underestimate the local effects that accelerate the wind. Also worth a look is the NOAA forecast for Maui, though the forecasts are only given to the nearest 5 knots so for windsurfing it’s only useful for a general idea of if it’s going to be windy or not, i.e. a forecast of 10 knots probably isn’t worth it, 15 knots and up probably is. If you’re looking for slightly lighter conditions for intermediates then getting on the water at 11am can work as the wind may still be building, or getting on later in the day after 4pm may also be worth a try which also keeps you out of the sun.
It’s definitely worth adding some local windsurfing insight into the mix by following Jeff Bennett’s Twitter Feed and his blog. The Marine Winds section of Glenn’s Daily Weather Narrative can give you a good overview of what’s happening.
Waves
The NOAA surf forecast gives you an idea of what size waves to expect. Remember that local conditions will affect this to, for example Lowers will probably be breaking smaller than Uppers and Hookipa.
