The Lowdown

Alright folks, Rusty here. Let's be straight with you. The next couple of weeks are looking pretty flat and unremarkable for our shores. We’ve got a long stretch of small, weak surf ahead, so don't get your hopes up for any barrels. The energy just isn't there for the most part. It’s a waiting game, plain and simple.

The outlook kicks off on Monday, August 10th, and honestly, it’s a non-starter. We’re looking at a tiny 1ft of swell from the WNW with a short 9-second period, and the energy is weak at 51. Monday morning is clean with light offshore winds, but it’s just not enough to ride. The wind clocks around and picks up in the afternoon, making things choppy. This is the story for the next few days: tiny waves and less-than-ideal winds.

We’ll see a little bump mid-week, but it’s not going to save us. Thursday, August 13th, sees the swell nudge up to 3ft, with the energy climbing into the moderate range (177 and 229). But the direction is still WNW and the winds are onshore or cross-shore, so it’s going to be messy and junky. Not worth your time.

Friday, August 14th, is the first time we get a glimmer of hope. The morning shows 3ft of WNW swell with a gentle offshore breeze, and it cleans up. It’s not big, but it’s the cleanest surf we’ve seen. The energy is a weak 109, but it's a start. The afternoon has a bit more size at 4ft, but the wind goes cross-offshore and it just doesn't look as good.

The weekend is a washout. Saturday, August 15th, has a brief window of clean 3ft surf in the morning with an offshore wind, but the energy is weak. It’s marginal. From there, it’s a real dry spell. We’re looking at a solid run of days with almost nothing on offer, just tiny, weak pulses with poor winds. That gap stretches from the 16th right through the 21st, with the swell barely reaching 2ft at best and the wind being mostly cross-shore or onshore. It's a bleak week, for sure. The water temp is sitting about average for this time of year, so at least it won't be freezing while you're staring at the flat ocean.

The only other day that gets a mention is Tuesday, August 18th. The morning shows a clean 3ft pulse from the WNW with a 7-second period, and energy at 131. It’s just about the best we’ll see, but it’s still only a 1 out of 10 situation. The afternoon gets chopped up again by a cross-shore wind. After that, we fade right back out. The swell just stays weak, and the wind stays messy, well into the following week.

Honestly, Larmor Plage is a fairly exposed spot, but a long-period WNW swell isn't its friend. It needs a more direct hit. This type of small, short-period swell just doesn't wrap in with any power. The highlight of this whole period is likely the early morning of Friday, August 14th, but that's a pretty low bar. It's going to be small and clean, but you'll be on a longboard if you're lucky. The rest of the time, you might be better off finding a different hobby for a couple of weeks. Keep the board in the car, but don't hold your breath.

Rusty, out.

Information about the Larmor Plage Surf forecast

The above surf forecast table for Larmor Plage provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Larmor Plage can be found by selecting the local surf guide option on the grey menu. Our Larmor Plage 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 (Larmor Plage) 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 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. 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.
