The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at Rest Bay for the next couple of weeks.

Right off the bat, I’ve got to be straight with you – this is a tough stretch. We’re looking at a solid 16-day window, but the vast majority of it is a write-off. There’s no surf worth chasing today or for the next week and a half, really. The pattern is just stubborn: poor surf conditions, ugly wind, and a whole lot of nothing. You’ll be waiting a long time, with no real standout session until we get into the second week of September.

The first sniff of anything that might get your heart rate up is around Monday the 14th of September. Early that morning, we see a pulse of swell coming in at 4ft from the WSW, with a 9-second period. The combined energy (318) is moderate, but the wind is onshore at 12 mph, which is going to mess it up. The afternoon doesn’t get any better with the wind picking up to 19 mph. It’s still poor surf, so don’t get your hopes up.

Then, on Tuesday the 15th of September, we get a bigger push. The swell builds to 7ft in the morning and 8ft in the afternoon from the WSW, with a period around 7 to 9 seconds. The combined energy jumps to 878 in the afternoon. That’s a lot of water moving, but the wind is a disaster – a near gale from the WSW at 31 mph. That’s onshore, destroying any chance of a clean wave. For a spot like Rest Bay, which is a beach and point setup, that kind of onshore wind just makes it a messy, blown-out soup. Honestly, with that much wind and that size, it’s looking more interesting for kite surfers than paddle surfers. This is only for experts, and even then, it won’t be pretty.

There is a brief moment of calm right at the end of the outlook. On Saturday the 12th and Sunday the 13th of September, the wind goes light and offshore from the ENE, and the conditions are clean. But the swell is tiny – only 1ft – so while it’s pretty to look at, there’s nothing to ride.

So, the best you can say is that the second week of the outlook has a bit more energy, but it’s blown to bits. The water temperature is about 69°F, which is much warmer than normal for this time of year, so at least you won’t be cold while you’re staring at the chop.

There’s no standout session here. It’s a long wait with very little pay-off. Keep your eye on the forecasts, but for now, I’d be finding something else to do.

Rusty.

Information about the Rest Bay Surf forecast

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

Rest Bay is 1 km (1 miles) from Porthcawl. If you plan a holiday in Wales - South East, look for hotels and other accommodation in Porthcawl. Porthcawl has rooms for a wide range of budgets as well as car hire and transport links.
