The Lowdown

Right now, things are looking pretty bleak out there. It’s not that there’s no swell – there’s plenty of it moving around – but the wind is going to be your enemy for a good stretch. We’ve got a lot of cross and onshore breezes that are going to keep the surface messy. Not a pretty picture.

Monday the 14th, we get a weak 2ft from the NE with an 8-second period. The energy is weak at 72. It’s cross and bumpy. Not worth the paddle.

Tuesday the 15th, the afternoon pushes a little to 4ft, but the period drops to 5 seconds. It’s all mush. Energy is still weak (52 in the morning, 68 in the afternoon). Another skip.

Wednesday the 16th, morning is 4ft, afternoon comes up to 5.5ft. Still that short 5-second period, so it’s going to be walled and bumpy. Energy is moderate at 158, but it won’t translate. Cross-shore wind is going to tear it up.

Thursday the 17th is the first time we see some real size and power, but the quality is poor. The swell jumps to 5.5ft with a 10-second period, and the energy is strong, hitting 522 in the morning and 426 in the afternoon. The problem is a fresh cross-shore breeze and lumpy water. It’s heavy, but it’s a fight.

Friday the 18th actually cleans up a little. The wind goes cross-off in the morning, and we have 4.5ft at 8 seconds. Energy is moderate at 250. This is the best looking day in this first stretch, but it’s not going to be epic. The afternoon is 5ft with a clean wind, energy at 320. If you’re desperate, this is your window. But the period is short, and the swell direction is a bit east for Windmills. This spot is a reef, fairly exposed, but its optimum is NNW. So this NE/ENE stuff isn’t ideal.

Saturday the 19th goes back to messy. Morning has 5ft but it’s cross and lumpy, and by the afternoon, the swell just collapses to 0.3ft. It’s a write-off.

Sunday the 20th has a clean morning with a cross-off wind and 4.5ft at 8 seconds. But the afternoon goes cross and lumpy again at 5ft. Energy is moderate (247 in the morning, 236 in the afternoon), but it’s not consistent.

From Monday the 21st through Wednesday the 23rd, we get a bit more push. Monday is 5ft to 5.5ft, but the wind is fresh and cross, making it lumpy. Tuesday is similar, with the energy building to 713 in the morning and 741 in the afternoon on the 23rd, with 6ft at a 10-second period. That’s some grunt, but it’s still cross-shore and chop. The period is decent, but the direction is still ENE, which is off for this spot.

Thursday the 24th has 5ft, but it’s cross and choppy. Energy is strong at 464 and 380. Still not good.

Friday the 25th, the wind turns cross-on and gets choppy. 4ft with a moderate breeze. No good.

Saturday the 26th, we drop back to 3ft, cross-on, and fairly choppy. Not great.

Now, Sunday the 27th, the wind swings north, and it’s cross-on in the morning and onshore in the afternoon. Swell is 3.5ft to 3ft, with a 10-second period. Energy is moderate to strong (307 and 233). But the direction is N, which isn’t the optimum, and the onshore wind kills it.

Monday the 28th is interesting. The swell drops to 2.5ft, but the period jumps to 15 to 16 seconds. That’s a very long period groundswell. Energy is strong, with 376 in the morning and 319 in the afternoon. But the wind is on in the morning and cross-on in the afternoon. The long period at a reef could be beautiful, but the size is small. This is a long-range, promising but less certain call.

Tuesday the 29th, the swell is still small, 2ft, with a 13-second period. The wind is light and cross-on. Energy is 140 to 251. Still, it’s clean-ish for a small wave, but

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.
