Alright, folks, Rusty here. Let's have a look at what Rest Bay has in store for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a tough start. We're looking at a real flat spell. For the first week and a half, from now through to about the 18th of July, there's basically nothing doing. Tiny, weak swell, poor conditions, the whole lot. You’d be better off cleaning the wax off your board than paddling out. It’s a real dry run for anyone itching for a wave.
Now, let's jump ahead to Saturday, the 19th of July. That’s where we finally see a flicker of life. The afternoon looks like the best bet of the whole outlook, and even then, it’s pretty marginal. We've got a WSW swell pushing in around 4ft and a gentle offshore breeze from the ENE keeping things clean. The combined energy is still weak at 95, so it’s not gonna be pumping, but it’s surfable. This is really the only standout window you've got – a small, clean option for a longboard or a fun shape. Just don't expect any barrels.
Before that, on the 18th, the afternoon bumps up to 4ft from the WSW with a clean cross-offshore wind. The energy is only 70, so again, small, but it’s the first time we see something that could be ridden.
Looking further out to the 20th, Monday, the swell picks up a bit more, 4 to 4ft, and the energy climbs to a moderate 147 then 181, but the wind swings onshore and cross-shore, ruining the surface. It’s messy, not worth getting excited about.
The water temperature at Rest Bay is 66°, which is much warmer than normal for this time of year – nearly 7° above average, so the wetsuit can be a little thinner. But with the surf being so small for so long, it’s a tease.
So, to wrap it up: the first ten to twelve days are a write-off. Your one real chance for a session is the afternoon of Saturday, 19th July when the conditions finally line up, albeit for very small surf. Keep an eye on the forecasts, but for now, it’s a waiting game.
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.
