The Lowdown
Alright, Rusty here. Let’s look at what’s on the table for the next couple of weeks.
To be straight with you, this is a tough stretch. Looking at the whole 16-day window, there’s no real green light for a good surf session. The pattern is pretty much locked in: a persistent cross-shore or cross-offshore wind from the ENE, which is the wrong angle for Windmills. The swell is coming from the same direction, mostly short-period stuff, and the water is going to be lumpy, choppy, or just plain messy for most of it.
The first real chance to even get a board wet comes up on Sunday the 16th of August. The morning is still a write-off, but by Sunday afternoon, the wind drops to a gentle breeze from the east at 9 mph, giving us a clean cross-offshore. The swell is 6 ft from the ENE with a period of 8 seconds. The combined energy is moderate at 394. It’s still marginal – the forecast only gives it a 1 out of 10 – but it’s the cleanest the surf will be all week. Expect a bit of a wait for the sets.
After that, the surf drops off quickly. Monday the 17th and Tuesday the 18th see the swell fade to knee-to-waist high (4 ft to 5 ft), with the energy dropping to weak levels (136-252). The wind stays cross-off, so it’s clean, but there’s just not enough push.
From Wednesday the 19th right through to the end of the month, we’re in a flat spell. The swell height drops below 3 ft for days, the energy is mostly in the double digits, and a few days even show a tiny 1.0 ft west swell. The wind doesn’t let up, staying cross-shore from the ENE. There’s a little bump in energy on the 24th (107), but it’s still tiny and lumpy.
The only real standout, if you can call it that, is a pulse toward the end of the window. On Friday the 28th of August, the swell bumps up to 6 ft from the ENE, with a period of 10 seconds. The combined energy is strong at 693. But it’s still cross-shore winds at 15-19 mph, making it lumpy. It’s not going to be a classic day, but if you’re desperate for a paddle and can handle some chop, it’s the biggest push of the whole forecast. That’s more of a challenge for experts only, well over 5 ft and with that messy wind.
To sum it up: the best bet is the late afternoon glass-off on Sunday the 16th, but keep expectations low. Otherwise, the log stays in the garage. A blank run like this is pretty normal for the area when the trade winds lock in. It won’t stay poor forever, but for now, it’s a waiting game.

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.
