The Lowdown

Alright folks, it’s Rusty here. Let’s have a look at what’s coming up for Gower at Mewslade Bay.

Honestly, we’ve got a bit of a flat spell on the cards for the next week or so. The first real chance of anything remotely surfable doesn’t show up until Sunday the 9th of August, which leaves us with a gap of about 10 days with no proper recommendations. It’s a tough stretch, but it’s not uncommon for this area.

The swell energy is looking weak for the entire first week, with the combined energy all sitting below 100, which is pretty gutless. Temperatures are a mixed bag; the water is currently sitting at 66°, which is 5° warmer than the long-term average. That’s a notable anomaly, meaning the water is much warmer than usual for this time of year.

Now, for the one standout that’s worth circling. Sunday morning, the 9th of August, we might see a pulse of swell. The forecast shows a 5ft swell from the WSW, with a period of 9 seconds. The combined energy jumps to 511 (moderate wave energy), which is the biggest we’ll see in the whole outlook. The wind is a gentle cross-shore from the WNW, which will keep the surface clean. The wave comment suggests it’s marginal, but it's the best on offer. The swell direction is WSW, which is close to the optimum SW direction for Mewslade Bay. That’s a point to note. However, the period is just under 11 seconds, so it’s not a classic groundswell, but it’ll have a bit of push. The break is exposed and fairly consistent, so there should be some waves. Do keep in mind that the break can get crowded sometimes.

Sunday afternoon is a bit of a write-off, with the wind picking up to 19 mph from the W, creating a lumpy cross-chop.

Monday morning, the 10th, we’ve got a drop back to 4ft, but the wind swings to a light cross-offshore from the NNW, meaning the surface will be clean. The combined energy is 136 (moderate wave energy). It’s a smaller option, but cleaner than anything else.

Tuesday the 11th and beyond, we’re back to small, weak, and poor conditions. The wind is mostly onshore or cross-onshore, and the swell drops right off again.

So, to sum it up: if you can wait, Sunday morning the 9th of August is your best bet. It’s the only window where the swell size and energy line up with a decent wind. It’s not going to be epic, but it’s the only real hope in this 16-day stretch.

Rusty.

Information about the Mewslade Bay Surf forecast

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