Alright folks, this is Rusty. Let’s be straight with you about Mewslade Bay. I’ve had a good look at the next 16 days, and I’m a bit gutted to say it’s looking like a flat spell for the most part. There’s no real surf to speak of on offer, so we’re in for a long blank run. The first recommendation doesn’t even come in until Friday, July 5th, and even then it’s a struggle.
From the start of the period through to the end, the swell is tiny and the wind is mostly in the wrong direction. The first few days, from July 5th through the 9th, it’s all cross-on to cross-off breezes with waves rarely breaking above 2 ft. The combined energy is weak, barely reaching 74 (74) on the best of those days. The water temperature is about average for the time of year, nothing unusual.
The only real glimmers come on Friday, July 12th, and Saturday, July 13th, when we see a long-period groundswell creeping in from the SW. On the 12th, the swell is a tiny 0.3 ft but with a period of 16 seconds. The wind is clean, cross-off from the east, and the energy is a paltry 15 (15). On the 13th, it’s a similar story: 0.3 ft swell, 20-second period, and clean offshores. The energy is just 20 (20). These are long-period groundswells, so the waves will be more shaped and the sets will be far apart, but honestly, for a beach break like Mewslade, it’s more likely to break straight and be a paddling exercise than anything you’d call a wave.
The spot is fairly consistent when there’s swell, but it’s inconsistent right now because there’s no swell. It’s an exposed break, but the optimum swell direction is SW, and we just don’t get any size from it in this window. It’s a tough one to call, but the truth is, there’s nothing here. Not even a rideable day for a beginner. It looks like a better spot for a picnic than a paddle-out for the next couple of weeks.
Keep your eyes on the charts, but don’t hold your breath. This is a proper blank run for Mewslade.
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.
