Hey, it’s Rusty. So here’s the deal for Mewslade Bay over the next 16 days – nothin’ doing. Zero surf worth mentioning from Monday July 6th all the way through Tuesday July 21st. Swell heights are pathetic – 0.2 to 2ft at best – and the wind is usually cross-on or cross, messing up any chance of a ride. The combined wave energy numbers are all weak, mostly in the teens or low 20s, nothing over about 74. Even on those glassy mornings like Thursday 9th and Friday 10th, you’re looking at maybe 1.0–2ft of limp mush.

Mewslade Bay is normally a fairly consistent intermediate spot that likes a SW groundswell, but this stretch is a total dud. The water is unusually warm – about 66°F, which is 7°F above normal – feels nice for a swim but not for surfing. A run this flat is rare around here, so it’s bound to pick up again. Just not this window. Hang tight.

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.

Mewslade Bay is 25 km (16 miles) from Swansea. If you plan a holiday in Wales - Gower, look for hotels and other accommodation in Swansea. Swansea has rooms for a wide range of budgets as well as car hire and transport links.
