The Lowdown
Alright crew, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks. I’ll be honest, it’s a tough one. We’re looking at a long stretch with no real surf to get stoked about – a big gap from the start all the way to the end of the 16-day run.
The only spot we’ve got on the map is Windmills, a reef break that’s only for the experienced. It’s fairly consistent, but when conditions don’t line up, it doesn’t matter how often it breaks.
From Thursday, July 30th, it’s all messy. A fresh cross-shore breeze kicking up lumpy chop. The combined swell energy is weak to moderate (348), with a short-period 1.4m swell coming from the ENE. Water temperature is 26°C – right around average for this time of year, nothing unusual. The onshore wind and short period just ruin any chance of a clean wave. The afternoon cleans up a little but still poor.
That pattern just keeps rolling through Friday, Saturday, and Sunday – ENE wind at 30–35 mph, cross-shore or cross-off, swell heights between 1.4m and 2.0m, but the period stays short and the energy never gets going. On Saturday, August 1st, the combined energy hits 492, but it’s still short-period windswell and the wind is a problem. Monday morning, August 3rd, winds drop a bit to 20 mph from the NE, but it’s still cross-shore and the wave comment is “poor surf conditions.”
We get a slight glimmer on Tuesday, August 4th – the period jumps to 11 seconds and the combined energy climbs to 546 – but the wind is still cross-shore and nothing’s changed on the wave quality front. The rest of the week and into the next is more of the same: moderate breezes, cross-shore winds, small short-period swell. It’s a grind.
Even by the tail end, on August 14th, we see a tiny 0.5m swell from the west with an 11-second period, but the wind is cross-off and the surface is still not clean.
So here’s the truth: Windmills has nothing going for it across the entire 16-day forecast. Wrong wind, poor swell quality, and every single session is marked as poor. If you’re into kiting, this wind might be your thing, but for a paddle surfer? Not much to work with. This kind of dry spell happens, so don’t throw your board in the shed just yet – forecasts can change.

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.
