The Lowdown
Alright, Rusty here. Let’s be straight with you – this outlook for the next 16 days is a quiet one. We’re looking at a long stretch of small, weak surf with hardly any energy to get excited about. The first recommendation doesn’t kick in until Friday, July 31st, and even then, it’s a struggle.
Right from the start on Friday morning, July 31st, it’s a tough one. Rest Bay is seeing a tiny 2ft swell from the west, with a short, weak period of just 5 seconds. The combined energy of all swells is a feeble 16, and that onshore WNW wind at 12 mph is just making things choppy and messy. It’s a real scratch session. The afternoon doesn’t get any better – the wind picks up to 22 mph from the west, pushing a 3ft, 4-second windswell that’s just blown out. The water temp is about average for the time of year, not that it’ll help much with the surf.
Saturday, August 1st, is more of the same. Another 2ft westerly swell with a 5-second period, and cross-onshore winds keep it choppy. The energy is still only 25. You’d be better off staying in bed.
Then we hit a little glimmer, but it’s for the small fry. Sunday, August 2nd, the swell drops to 1ft from the WSW, but the wind goes glassy in the afternoon from the SSW at 3 mph. The period stretches to 8 seconds, and the combined energy is a measly 13. It’s clean, but it’s tiny. If you’ve got a foamie and want to get wet, you could, but it’s not a real surf.
Monday, August 3rd, is similar. Clean morning with a 1ft WSW swell, 9-second period, and a light cross-offshore breeze from the ESE. Again, the energy is low (30). It’s surfable for a beginner, but that’s about it.
After that, it’s a long, dry spell. From Tuesday, August 4th, all the way through to Saturday, August 15th, every single session is rated as poor surf conditions. The swell never gets above 2ft, the periods are short, and the wind is often onshore or cross-onshore. The combined energy readings are in the single digits or low teens. There’s a brief moment on Wednesday, August 12th, with a 1ft WSW swell and a 9-second period, with glassy conditions in the afternoon, but the energy is only 15. It’s a tiny, clean wave, but nothing to write home about.
So, the honest truth is there’s no standout here. The best on offer is that tiny, clean glassy period on Sunday, August 2nd, or the clean morning of Monday, August 3rd, but only for the absolute beginner. For anyone else, it’s a long, blank run. The setup is so weak and wind-affected that it’s more interesting for a kite surfer than a paddle surfer. The forecasts can always change, so keep an eye, but for now, it’s a flat spell.
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.
