Biarritz - Cote des Basques Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what's coming our way for Biarritz - Cote des Basques. This is a classic beach and reef setup that's exposed to the west, so it's going to be the main player in this outlook.

We've got a bit of a slow start, but things are looking up. The forecast period kicks off with a real treat. Sunday, September 13th is the standout to kick things off. The morning session is going to be pure gold. We're looking at a clean 4.3ft swell from the NW, with a nice long 13-second period (that's groundswell energy for you). The wind is glassy from the ENE at 3 mph. It doesn't get much better for clean conditions. The water is sitting at 73°, which is a solid 4.3° warmer than normal for this time of year, so you'll be comfortable in a spring suit. The combined energy is moderate at 545, so there's some punch there. This is a great session for all levels. The afternoon gets a bit cross-on, so the morning is the pick.

Monday, September 14th follows a similar pattern. Another glassy morning with ENE wind at 3 mph, and the swell holds at 4.3ft from the NW with an 11-second period. The energy drops slightly to 453, but it's still a fun, clean wave. The afternoon cross-on wind messes it up a bit, so again, dawn patrol is your friend.

Tuesday, September 15th is a write-off. Swell drops to 2.6ft with onshore winds. Not worth paddling out.

Wednesday, September 16th brings a bit more size, up to 4.6ft, but the period is a short 7 seconds and the wind is cross. The morning might offer a few crumbly ones, but it's not going to be great.

Thursday, September 17th is another banger of a morning. The swell is up to 5.6ft from the NW with an 11-second period, and it's glassy again with NNW wind at 3 mph. The energy is strong at 663, so there's plenty of push. This will be a fun, clean morning. The afternoon gets cross-on, so don't sleep in.

Friday, September 18th is a messy day. Onshore wind and a dropping swell. Not much to get excited about.

Now, here's the big one. Saturday, September 19th is the real standout of the entire outlook. The morning is looking absolutely pumping for experienced surfers. We're talking a solid 7.2ft swell from the NW, with a long 13-second period. The wind is offshore from the ENE at 3 mph, keeping it clean. The combined energy is a whopping 1619, which is very strong. This is big, powerful groundswell. Because of the long period, the sets will be well-spaced, and it'll be best at the peakier parts of the reef. The afternoon sees a 6.6ft swell with cross-shore wind, so the morning is the window for the experts.

Sunday, September 20th still has good morning conditions. The swell is 5.9ft from the NW, 12-second period, with glassy ENE wind. Energy is high at 939. This is a great session for strong intermediates upwards. The afternoon gets cross-on and bigger (6.9ft), so it gets a bit messy.

Monday, September 21st has the biggest swell of the run, hitting 7.2ft from the NW with a very long 14-second period. The energy is massive at 1891. However, the morning wind is onshore from the W, which will make it bumpy. The afternoon is cross-on. This is a day for experts only, and you'll be dealing with some wind on the face.

The rest of the week settles down a bit. Tuesday, September 22nd through Thursday, September 24th sees a consistent 5.2ft to 3.6ft NW swell, with clean glassy mornings. These are solid, fun days for all levels.

Friday, September 25th is another standout morning. The swell picks back up to 5.2ft from the NW with a 13-second period, and the wind is a nice cross-off from the SE at 3 mph. Clean and punchy. Energy is 753.

The final weekend, September 26th and 27th, sees the swell holding around 5.9ft to 6.6ft, but the winds are more onshore and cross-on, making conditions less appealing. The morning of the 27th does have an offshore wind, but it's strong at 12 mph, so it'll be clean but a bit blustery. The surf size drops a bit.

The last day, Monday, September 28th, has a cleaner morning with offshore wind and a 3.6ft NW swell. A fun, small end to the outlook.

To sum it up: The absolute best on offer is the morning of Saturday, September 19th for experienced surfers, and the mornings of Sunday the 13th and Thursday the 17th for everyone else. Get on it early.
