The Lowdown
Alright, Rusty here. Let’s be straight with you – this is a tough one to call. The next 16 days at Rest Bay are looking pretty grim, with no real standouts to get excited about. The forecast is plagued by poor surf conditions across the board, with a whole lot of cross-on and onshore wind messing things up. The main issue is the wind direction and the lack of quality swell. Let’s break it down.
We start off on Monday the 7th with a bit of energy – a 4 ft swell from the WSW, but it’s coming with a 12 mph cross-on from the WNW, creating choppy conditions. The combined energy is moderate at 633, but it’s not doing us any favours with the wind. The water temp is a very unusual 67°F, which is 6°F warmer than normal – that’s a real anomaly for this time of year. The morning session is a write-off, and the afternoon gets worse with a 19 mph onshore wind.
Tuesday the 8th is more of the same rubbish. A 5 ft swell but the wind is all over the place – cross-shore in the morning, then a fresh cross-on in the afternoon. Not a sniff of a clean wave.
Wednesday the 9th sees the swell drop to 3 ft and then 2 ft, with energy falling to 109 and 93. Still no clean wind. The cross-shore and cross-on wind just won’t let up.
Thursday the 10th is flat and tiny – 1 ft and 1.0 ft swell with hardly any energy. Don’t bother.
Friday the 11th has a 3 ft swell, but the wind is onshore or light cross-on. The energy picks up to 169 in the morning, but the wind state is unknown, so it’s a gamble. Not worth it.
Saturday the 12th is a real tease. The morning is glassy – a 2 ft swell with a light southerly breeze, but the energy is only 38. The surf is tiny and poor, so even though it’s clean, there’s nothing to ride. The afternoon gets a 12 mph onshore. A classic case of “glassy but flat.”
Sunday the 13th has a 4 ft swell, but it’s a short-period 7 seconds, and the wind is cross-on and onshore, creating choppy, lumpy conditions. Energy is 128, but it’s messy.
From there, it’s a slow decline. The swell sticks around 2 ft to 3 ft through the middle of the week with strong, gusty winds, especially on Tuesday the 15th with 25 mph onshore, and then it just fades away. By the 19th, we’re looking at 1.0 ft waves with next to no energy. The last few days, from the 20th to the 22nd, are basically flat – 0.3 ft to 0.7 ft – with strong winds and no energy to speak of.
So, the honest truth is, there’s nothing here for a surfer over the next 16 days. The forecast is a long, flat, and windy run. Don’t hold your breath. It’s a blank run, but for this area, that’s not too unusual. The forecasts can change, but right now, there’s nothing to recommend. If you’ve got a kite, this might be more interesting than a paddle.
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.
