The Lowdown
Alright, let’s get into it. Rusty here, giving you the straight-up story on what’s happening at Windmills.
First up, don’t get your hopes up too high. The whole 16-day window is a tough one. There’s not a single day that I’d call good. The wind just won’t play ball – it’s stuck in a cross or cross-off direction the entire time, and that ENE wind is relentless. Most of the time it’s a fresh breeze, sometimes a moderate one, but always spoiling the shape. The water temp is sitting at 80°, about normal for this time of year.
We start with a bit of a nothing burger on Sunday the 16th. There’s some swell around, 7ft from the ENE at 9 seconds in the morning, but with that east wind at 22 mph, it’s messy. The combined energy is moderate at 600, but the conditions are just poor. That afternoon, it drops to 5ft, still cross-off, and the day’s a write-off.
Monday the 17th is no better. 5ft to 5ft of short-period junk, with the wind still howling. Tuesday the 18th morning, there’s a weird little 0.7ft blip from the WSW with a very long 17-second period, but it’s not worth paddling for. The energy is a weak 41, and it’s messy.
Honestly, day after day it’s the same story. The swell stays between 2ft and 8ft, almost all from the ENE, with periods stuck between 5 and 8 seconds. The wind never lets up. By Saturday the 22nd, we’ve got a 5ft afternoon with a fresh cross breeze, but the surf quality is rated poor.
The last week doesn’t bring any relief. By Friday the 28th, the swell builds to 8ft and 8ft, with combined energy climbing into the strong range (579 and 644), but it’s all tied to that same ENE direction and a moderate cross-shore wind. For a reef break that needs a clean offshore from the SSE to work, this setup is all wrong. The swell direction is the exact opposite of what this spot needs, and the wind direction is terrible.
Even when the swell gets big enough to get your attention – like that 8ft on the 28th – it’s only good for experts, and the conditions are so lumpy and chopped up it’s hardly worth it.
With the constant cross-shore wind and the punchy, short-period swell, this setup actually looks more interesting for kite surfing than paddle surfing.
So there you have it. A full 16 days of nothing worthwhile at Windmills. Sometimes it’s just like that. Forecasts can change, but right now, I’d leave the board at home.
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.
