The Lowdown
Alright, let’s get into it. The forecast is looking bleak for Rest Bay over the next 16 days. There’s hardly any decent swell on the cards, and what is there is pretty weak.
We kick off on Wednesday the 29th of July, and honestly, it's a bit of a write off. A tiny 2ft swell from the west with a short, weak period of 5 seconds. The combined energy is barely a whisper at 15, and it’s blown out with a 12 mph onshore wind. Not worth paddling out for. The water is sitting at 69°, which is about 8° warmer than normal for this time of year - very unusual.
Heading into Thursday, the 30th, it’s more of the same. A meager 2ft to 2ft swell from the west, still short period (5 secs), with cross-onshore winds and energy readings staying in the doldrums (28 to 42). Friday and Saturday look similar; tiny, weak swells and onshore or cross-onshore winds. The energy levels are stuck in the teens and twenties – basically flat. On Sunday the 2nd of August, we get a brief drop in wind, with a light 6 mph breeze and a tiny 1ft west-southwest swell. It looks clean on the Sunday morning, but there’s just no push in the water.
The following week doesn’t give us much hope either. Monday the 3rd of August has clean, offshore winds from the east at 16 mph but the swell is only 1ft from the southwest. The energy at 21 is weak, and a 9 second period for that size isn’t going to do much. From there, it’s tiny dribbles of swell – 0.3ft to 0.7ft – with some clean, glassy moments early on the 6th and clean offshore winds on the 7th and 8th of August, but again, no wave size to speak of.
The best looking days are the 8th and 9th of August, where we finally see consistent offshore to cross-off winds from the east and a bit of a longer period (9 to 10 seconds), but the swell height is still only 0.7ft to 1ft from the west-southwest. The combined energy on the morning of the 9th gets up to 31, which is still very weak. For a spot that’s a beach and point, this setup looks like it might have more potential for kite surfing than paddle surfing given the clean wind and lack of wave height.
The last few days from the 10th to the 13th of August are back to tiny, weak swells with onshore or cross-onshore winds, so it's a flat finish.
There are no standout options in this 16-day window. It’s a long, flat stretch for Rest Bay – a blank run that’s not too unusual for this time of year, but it’s still a tough pill to swallow. Sure, the forecasts can always change, but right now, I’d leave the board in the car.

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.
