The Lowdown
Hey, Rusty here. Let me put it plain: Windmills is looking like a long, frustrating stretch with nothing but cross-shore winds and messy, short-period swell. There’s no good surf on offer for the next couple of weeks. The first few days are a total loss, with small waves and chop. The water temp is about 79°F, which is normal for this time of year.
From Friday the 17th through to Monday the 27th, it’s a constant battle with ENE cross-shore winds at 12-22 mph. Swell heights are pitiful, from 2 ft to 7 ft, with periods as low as 5 to 8 seconds – just windswell slop. The combined energy values range from 212 to 530 (moderate to very strong), but the cross-shore wind ruins everything. On Saturday the 25th and Sunday the 26th, the swell jumps to 7 ft with energy over 500 (very strong), but with 7-8 second periods and cross-shore wind, it’s going to be a lumpy, blown-out mess, more suitable for kites than surfboards. This is an advanced reef break, and you’ll need to be on your game.
Then, a faint flicker. On Wednesday the 29th of July afternoon, the swell picks up a bit of period – 12 seconds – with energy at 446 (strong). Thursday the 30th holds 11-second period with 1.1m (4 ft) swell and energy in the 320-340 range (strong). The wind is still cross-shore from the ENE at 12 mph, so it’s not clean, but longer-period swell can offer better shape and more punch. Friday the 31st keeps the period at 10 seconds with 0.9m (3 ft) swell and energy around 200-240 (moderate). On Saturday the 1st of August, there’s a 13-second period swell from the west at 0.5m (2 ft) with energy 242 (moderate). Again, cross-shore wind. The optimum swell direction for this break is NW, so the ENE swell isn’t ideal, but the longer periods might make it work a bit. Crowds are often here, so expect company. This is a long-range hint, so less reliable.
In short, it’s a hard slog with one small, uncertain window at the very end. Everything else is poor. The conditions are better for kite surfing than a relaxed paddle. That’s the call.
Rusty.

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.
