The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the Le Porge area over the next couple of weeks.
First off, the water temp here is sitting at 78°F, which is more than 5°F warmer than usual for this time of year – that’s pretty unusual, so you’re in for a proper warm bath.
The next 16 days start with a bit of a dud. We’ve got no real surf to speak of from now through to Wednesday the 19th of August. It’s mostly small, weak, and wind-affected. The swell is tiny at 1ft to 3ft, period is short, and the wind is mostly onshore. Not worth paddling out.
The first real chance to get wet comes on Thursday the 20th of August, in the morning. It’s small, around 3ft from the WNW, with period stretching to 11 seconds – that’s a nice groundswell pulse. What makes this stand out is the wind: glassy. Light air. The combined wave energy is moderate (196). It’s surfable, and the conditions are clean. It’s a beginner-friendly spot, so the crowd factor could be an issue – I’d expect some company out there.
Friday the 21st of August is probably the pick of the first week. Morning session is clean with cross-offshore winds from the north at 9 mph. Swell is a bit bigger at 4ft from the WNW, period around 10 seconds, and the energy is solid moderate (256). That’s where you want to be. The afternoon gets blown out by a cross-onshore wind, so make it a dawn raid.
Saturday the 22nd is worth a mention too. Another glassy start on the Saturday morning, with around 3ft from the NW. Energy is moderate (103) but the conditions are clean. Afternoon sees cross-offshore winds again, with a small 3ft swell from the NW. The swell period drops to 8 seconds though, so it’ll be a bit weaker and less organized.
Sunday the 23rd of August has a glassy morning again, but the swell is only 2ft from the NW with a short 7-second period. Very ordinary, but clean if you’re desperate.
After that, the surf turns pretty poor from Monday the 24th through to Sunday the 30th of August. Swell stays small or weak, and wind is mostly cross-onshore or onshore. There’s one day – Thursday the 27th – where the swell picks up to a couple of 3ft waves, but the wind is moderate cross-onshore, so it’ll be choppy and frustrating.
Now, the standout of the whole period looks like Friday the 28th of August. We’ve got a solid 5ft from the WNW in the morning, with a very long 12-second period – that’s quality groundswell. The combined energy is strong (725). The catch is the wind is cross-onshore, and the surf is labelled marginal, so tide might be an issue. But if you know the sandbanks and the tide, there could be some fun, powerful walls. This is one for experienced surfers; it’ll be too much for beginners. The afternoon holds at 5ft with a similar long period, but the wind goes fully onshore, so the morning is your window.
Monday the 31st of August sees another pulse: 7ft from the WNW in the morning, period only 6 seconds though. That’s short-period wind swell, messy and without much push. Energy is still moderate (321). The afternoon jumps up to 6ft with 11-second period, energy at 946 – strong. But again, wind is onshore or cross-onshore and the surf is marginal.
Then into September, Tuesday the 1st of September packs some real power: 6ft from the WNW with a very long 14-second period, energy at a huge 1262 (very strong). That’s proper groundswell, but the wind is a fresh 19 mph cross-onshore, making it lumpy and poor. Not a day for a grovel board. This is expert-only territory with that size and chop.
Overall, the most promising window is Friday 21st August morning for the best combo of clean conditions and decent swell for the average surfer, and Friday 28th August morning if you’re after size and have an eye for a tricky tide. Everything else is a marginal call.
Rusty.

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