The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the only spot that's even in the conversation, Windmills. Honestly, looking at the 16-day window, it's a pretty bleak run. There's no real stand-out window, and the consistency is shot. For the advanced crew only, we're looking at a long stretch of messy, cross-shore wind that just won't let up. The water is sitting at a normal 80°F for this time of year, so no drama there, but that's about the only thing going for us.

The most usable surf shows up around August 15th and 16th. Saturday the 15th sees a push of 8 ft swell (ENE) with strong, messy cross-shore wind in the morning, but the afternoon cleans up to a clean 8 ft (ENE) with a near-gale cross-offshore breeze. The combined energy is strong at 937 (moderate wave energy). That's big, fast, and windy – only for experts who don't mind a battle. Sunday the 16th morning has 6 ft (ENE) with cleaner cross-off wind, energy dropping to 490 (moderate wave energy). It's the best combo of size and shape in the whole run, but it's still not pretty.

After that, the swell drops right off. Monday the 17th gives us clean 4 ft (ENE) waves with moderate breeze, but the energy is weak (228). From the 19th through the 28th, it's a frustrating mix of tiny swell (2 ft to 5 ft), mostly cross-shore winds, and pitiful energy readings. The 27th afternoon shows a weird spike with a 3 ft swell but a very long period of 17 seconds (very long period groundswell) pushing the energy to 744 (moderate), but it's still cross-shore and small – likely straight and tough for this reef. Then the 28th offers 5 ft (ENE) again, but the magic is gone. For a reef like Windmills, this is a grim stretch; the reef needs a clean, lined-up swell and offshore wind to shine, and we're getting neither.

Honestly, if you're a kite surfer, the strong cross-shore and cross-offshore winds from the 15th through the 17th might look more exciting than what's on offer for paddle surfing. If you're hanging on for a wave, Sunday morning the 16th is your only real shot, and even that's a stretch. This place doesn't stay flat forever, but this is a solid blank run for quality surf.

Information about the Windmills Surf forecast

The above surf forecast table for Windmills provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Windmills can be found by selecting the local surf guide option on the grey menu. Our Windmills surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Windmills) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Windmills may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Windmills is 20 km (12 miles) from Wailuku. If you plan a vacation in Maui, look for hotels and other accommodation in Wailuku. Wailuku has rooms for a wide range of budgets as well as car hire and transport links.
