Saint Leu Surf Forecast and Surf Report

Alright, Rusty here. Let's break this down.

We’ve got a good run of surf coming, and the big one to aim for is Wednesday the 16th – that’s the day that’ll have everyone talking. Big swell, clean conditions, and light wind.

Sunday 13th September – Saint Leu kicks it off with a 6ft SSW groundswell, 17-second period. That’s a long interval, so the waves will have plenty of power. The wind is light offshore from the SSE at 6 mph, so the surface will be clean. Water temp is 75°, about normal for the season. Combined energy is strong at 2136. This is an advanced wave, so only the experienced crew should be out. Crowds can show up here, so get in early. Afternoon sees it bump to 7ft, still clean with a gentle offshore.

Monday 14th drops a bit to 5-6ft in the morning, still clean. The afternoon gets a little windier, but it’s still surfable.

Tuesday 15th is solid again. Morning has 6ft SSW groundswell with an 18-second period – that’s a long lull between sets but when they come, they’ll be lined up and powerful. Wind is fresh offshore at 18 mph, so it’ll be clean but a bit blowy. Energy is very strong at 2612. Afternoon is about 6ft, same direction.

Now the highlight: Wednesday 16th September. Morning brings a big 10ft S swell with a 15-second period. Wind is light offshore, just 6 mph from the SE, so it’ll be glassy. Combined energy is massive at 4340. This is big, powerful, expert-only surf. If you’re not comfortable in solid waves, stay on the beach. The afternoon holds the same size, a few clouds but still clean. This is the best session of the whole window.

Thursday 17th drops in size. Morning is a bit messy with a cross-onshore wind, but the afternoon turns glassy with a 5ft SSE swell – nice for a session, but not the standout.

From Friday 18th onwards, the surf fades. The weekend sees waves drop to around 2-3ft, with some onshore and cross-shore winds. There are a few clean moments on the 20th and 22nd with waist-high leftovers, but nothing compared to the mid-week pulse.

Monday 21st afternoon has a small 2-3ft SSW swell with a 17-second period, so there’s energy but not much height.

Tuesday 23rd picks up again to around 4ft with a moderate offshore, and Thursday 24th morning is glassy with a 3-4ft SW swell – a nice little session if you’re around.

After that, it’s small and clean but nothing special. The final week has waves in the 2ft to 4ft range, mostly clean or glassy, but very small.

So the main takeaway: Wednesday 16th at Saint Leu is the standout with 10ft S swell and glassy conditions. Tuesday 15th and Sunday 13th are also quality. After that, it’s small clean windows for a paddle, but no big waves.
