The Lowdown
Alright, here's the deal on Larmor Plage. We're staring down a real dry spell for a week and a half. Nothing worth paddling out for until we hit August 9th. That’s a long, flat gap.
From July 27th all the way to the morning of August 9th, it's tiny. Wave heights are mostly under 3 feet, periods are short, and the wind is trash. The energy is pathetic (values like 295, 80, 68... down to 3). Cross-on or cross-shore breezes have everything chopped up. Don't bother.
Then on the morning of Monday, August 9th, we see a change. A 7ft WSW swell shows up with an 8-second period, and the energy is moderate (510). Problem is, the wind is a light cross-onshore. It's called “marginal.” For a beginner break, 7ft is big—and over 8 feet is expert only. This is borderline too big and messy for most.
Your real chance comes on Tuesday, August 10th in the morning. A 7ft WSW groundswell with a 10-second period, and the energy is strong (1728). The wind is light and cross-shore, which is the cleanest you'll get. But at 7ft, this is a session for experienced surfers only. The afternoon pushes to 8ft, but a 25 km/h cross-off wind will mess up the face.
Then we hit the standout: Tuesday, August 11th morning. We’ve got a solid 6ft W swell, 10-second period, and strong energy (1174). The wind is light from the NNW, giving us clean, cross-off conditions. The report says "expect very good surf conditions." This is your moment: proper size, clean lines, but it's advanced-only territory. The afternoon falls apart as the wind turns onshore again.
So the pick of the entire 16-day window is the morning of August 11th. Larmor Plage will be pumping with a 6ft W swell, glassy conditions, and plenty of energy. Crowds are possible, so go early. The water is a touch warmer than average for this time of year at 67°, nothing unusual.
After that, it drops back into small, weak, onshore slop. If you're a beginner, skip this whole forecast. If you've got the chops, circle August 11th on your calendar.

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 Larmor Plage 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.
