The Lowdown

Imperial units:

Alright folks, Rusty here. Let’s be real — the next two weeks at Windmills are mostly a bust. We’ve got a long dry spell before anything worth paddling out for shows up. Water temp is running 80°F right now, which is about normal for this time of year, so no surprises there.

From Saturday the 5th through Sunday the 6th, it’s ugly. Rain showers and cross-shore ENE winds at 15–19 mph, with lumpy cross-chop. Swell is around 6 ft but it’s coming from the ENE at 14 seconds — that’s a long-period groundswell, but the wind is killing it. Not your day.

Monday the 7th stays poor — 22 mph cross winds in the morning, though by afternoon it cleans up a little with 16 mph cross-offshore and 6 ft ENE swell. Still only marginal — not worth skipping lunch for.

Now here’s the standout — Tuesday the 8th. Morning is the pick of the whole stretch. Clear skies, gentle offshore SSE wind at 9 mph, and a 6 ft swell from the WSW at 12 seconds. Combined energy is 1283 — that’s strong, solid wave energy. This is clean, powerful reef surf, and for advanced crew it’s gonna be cooking. Afternoon drops to 5 ft but stays clean with SE cross-offshore — still good, just a bit smaller. That’s your day, no doubt.

Then it falls apart again. Wednesday the 9th and Thursday the 10th bring back ENE cross-winds at 16–19 mph, short-period junk at 7–8 seconds, and energy dropping into the low 200s — weak and chopped. Friday the 11th through Sunday the 13th stay poor, with winds shifting but never going offshore, and swell hanging around 3–5 ft but all short-period and cross-shore. Nothing rideable.

Monday the 14th through Wednesday the 16th — that’s the 14th to the 16th — we see 6–6 ft swell but it’s ENE at just 7 seconds, and winds are cross-on or cross. That’s messy, fat, and lumpy. Not for paddling — honestly, this setup looks more interesting for kitesurfing than surfboards.

Thursday the 17th and Friday the 18th stay marginal, with ENE cross-off winds on Friday morning bringing a bit of clean but still short-period 6 ft ENE swell. Then the 19th and 20th close things out with more cross-wind and weak, short-period leftovers.

So bottom line — Tuesday the 8th is the only true standout. Everything else is a write-off or at best a sneaky afternoon session if you’re desperate. Keep your hopes low, and when that Tuesday morning window opens, go get it. This is Rusty, signing off.

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.
