The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for the coming weeks.

Well, I’ve got to be straight with you—this is a tough one. The only spot in the mix is Windmills, and looking at the whole 16-day window, I just can’t find a session worth getting excited about. Every single time slot comes back with a score of zero, which is a real bummer. The swell is there, but the wind is just relentless, blowing from the east-northeast at 19 to 22 mph for most of the first week, keeping things lumpy and cross-shore. The water temperature is about average for this time of year, so no surprises there.

We kick off Friday, 31 July, with a clean sky but a fresh 22 mph cross-shore wind. Swell is around 5 ft to 7 ft from the east-northeast with a short period of only 6 to 7 seconds, giving us a combined energy of 254 to 311—moderate, but the wind just kills it. The surf is poor, lumpy cross-chop. Saturday and Sunday don’t let up; still 22 mph winds, still messy. The swell holds around 6 ft to 6 ft, and the energy climbs a bit, up to 435 and 504, but with that onshore breeze, it’s just a washing machine. Monday, 3 August, the wind eases to 12 mph, but it’s still cross-shore, and the swell drops to 4 ft to 5 ft with a period of 8 seconds. The energy is weaker now, around 222 to 306. Still poor conditions.

Tuesday, 4 August, brings a shift in wind direction to the northeast at 9 mph, and the swell period stretches to 11 seconds, which is a nice long-period groundswell. The energy is moderate at 346 to 425. But the wind is still cross-shore, and the surf remains poor. For a reef break like Windmills, that longer period could have been magic with the right wind, but it’s just not clean. Wednesday morning, 5 August, we get a brief moment of cross-offshore wind from the east at 16 mph, and the wave comment says “clean.” The swell is only 3 ft with a 9-second period, and energy is low at 179. It’s the best of a bad bunch, but still a zero score. The next few days are more of the same: cross-shore winds, lumpy conditions, and swell heights bouncing between 3 ft and 5 ft.

By the second week, from 10 August onwards, the wind stays strong, mostly 19 to 22 mph from the east-northeast. The swell gets a bit of a kick on Sunday, 9 August, with 7 ft from the east-northeast and energy up to 461, but the period is only 7 seconds, so it’s short-period windswell, and the wind is still cross-shore. The water is still average temp. Then, around 13 August, we see a weird shift: a tiny 2 ft swell from the west with a very long period of 14 seconds, and the wind turns cross-offshore from the east-northeast, giving us clean conditions. But the energy is low to moderate, 119 to 161, and the surf is still rated poor. On 15 August, we get a 2 ft west swell with a 14-second period and energy of 274, but the wind is back to cross-shore and lumpy.

Honestly, there’s no standout here. The best-looking conditions are those Wednesday and Friday mornings with clean, cross-offshore wind, but the swell is just too small and weak to make anything of it. If you’re a beginner, the swell rarely goes over 5 ft, so that’s not a problem, but the wind and chop will make it a frustrating paddle. For experts, there’s nothing over 7 ft, so no real power. The setup is a reef, so it’s not kite-friendly either. This is a blank run for the area, plain and simple. Forecasts can change, but right now, I’d leave the boards in the car.

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.
