The Lowdown
Alright, Rusty here. Let’s see what we’ve got.
Honestly, mate, this is a tough one. We’re looking at a long, bleak stretch ahead. The first surfable window doesn't even open up until Monday the 17th, and even then it’s nothing to write home about. Before that, we’ve got a solid 8-day gap of proper non-starters—just howling cross-shore winds from the ENE, choppy lumpy mess, and poor surf conditions day after day. Not a single wave worth paddling for.
The only break on the cards here is Windmills. It’s a tricky reef setup for advanced surfers only, and it’s fairly consistent but needs a clean window. That window finally appears on Monday the 17th. The early morning brings in a moderate 4 ft swell from ENE, with a period of 8 seconds, and the wind swings to a light offshore from the south at 9 mph. That’s a clean, surfable wave, even if the conditions are fairly ordinary. The afternoon cleans up even more—offshore breeze from the SSE at just 6 mph, with the swell dropping slightly to 4 ft. It’s small but workable. Combined wave energy is moderate at (253) in the morning and dropping to (184) by the afternoon.
Tuesday the 18th is a step back. The wind goes cross-shore again, the swell stays around 4 ft to 5 ft but the energy is still moderate (208) and (289). It’s not terrible, but it’s not clean either. The rest of the week is pretty forgettable, with cross-shore winds and chop dominating.
If I had to pick the absolute best of a bad bunch, it’s Monday the 17th afternoon at Windmills. Light offshore wind, clean face, and a little waist-to-chest high set from the ENE. That’s your window. It won’t be epic, but it’ll be the only surfable moment in a fortnight of junk.
Water’s sitting at 80°F, which is right around the normal mark for the time of year—nothing unusual there.
Stay patient, boys. This is a quiet spell.

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.
