The Lowdown
Alright mates, Rusty here. Let’s break down what the ocean’s got in store for us over the next couple of weeks. It’s a real mixed bag, so let’s get straight to it.
We’re starting out pretty flat and sleepy. The water’s running at a warm 76°F, which is much warmer than usual for this time of year. Nice for a paddle, at least. But the waves? Nothing doing. The first couple of days are a complete no-go, just tiny, weak dribble. You’re better off checking your gear.
Thursday the 27th, the ocean wakes up a little. We're talking tiny, ankle-high waves. Ordinary. The morning is glassy with light wind, so you could get a few grovelly ones in, but the energy is weak. It’s just a hint of what’s to come.
Friday the 28th sees a real bump, waves up to around 6 feet. But the wind is onshore and messy, turning it into a washing machine. There’s some energy behind it, but it’s not clean. A day to skip.
Saturday the 29th is where the fun begins. The morning is the clear winner. The wind goes offshore and light, and we’ve got solid 6 feet of northwest swell with a 9-second period. The energy is building to a moderate 481. It will be clean and punchy. Get out there early. The afternoon gets chopped up, so make that morning session count.
Sunday the 30th is a letdown. Onshore winds kill the quality, and the swell, while around 4 to 5 feet, is just messy. A day for other plans.
Monday the 31st is a cracker of a morning. Glassy conditions with 6 feet of northwest swell, and the energy is strong at 470. This is another dawn patrol special. Clean, lined-up waves before the sea breeze comes in and mucks up the afternoon.
September 1st, Tuesday morning, is again worth setting the alarm for. Glassy with 4 feet of swell and a slightly longer 10-second period. The energy is moderate at 364. It’ll be a bit more relaxed, cleaner shape.
From Wednesday the 2nd through Thursday the 3rd, the swell backs off to around 3 feet. It’s small, but the conditions are clean, especially Thursday morning with light offshore winds. Perfect for a longboard and just cruising.
Then we hit a flat patch. Friday the 4th and Saturday the 5th, the swell drops right out, and the wind goes onshore. The energy is nearly zero. It’s a classic blank run. The ocean just takes a breather.
Sunday the 6th, the energy starts to come back, but it’s still a bit lumpy. Monday the 7th is cleaner with morning glass and 3 feet of swell. Tuesday the 8th, the size jumps back up to 5 feet, but again with an onshore wind, so it’s not great.
Now, for the standout of the whole run, it’s the morning of Wednesday, September 9th. The wind dies completely – dead calm, glassy as a lake. We’ve got 4 feet of clean northwest swell and a period of 9 seconds. The energy is moderate at 255. That is the session. Those clean, fun waves will be all yours if you can get out there. After that, the swell fades again.
So, to put it plainly: the first few days are a write-off. Your best windows are the mornings of Saturday the 29th, Monday the 31st, and Tuesday the 1st. But if you can only choose one, make it the glassy morning of Wednesday the 9th. It’s the cleanest and most promising of the fortnight.
If the swell gets over five feet, the beach gets more challenging, so the beginners should stick to the smaller, cleaner days on the 2nd and 3rd.
Catch you in the water.
Rusty.

Information about the Boucau Surf forecast
The above surf forecast table for Boucau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boucau can be found by selecting the local surf guide option on the grey menu. Our Boucau 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 (Boucau) 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 Boucau 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.
Boucau is 5 km (3 miles) from Biarritz. If you plan a holiday in Landes, look for hotels and other accommodation in Biarritz. Biarritz has rooms for a wide range of budgets as well as car hire and transport links.
