Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s break down Mewslade Bay for the next couple of weeks. I’m not gonna sugarcoat it – this is a tough stretch. The forecast shows almost nothing worth paddling out for, so keep your board in the car and your hopes low.
We start Friday 3rd July with a small 3ft swell from the WSW and a 10-second period, but the cross-onshore wind is messing it up. Water temp is 67°, which is much warmer than normal for this time of year – over 7° above average, very unusual. But don’t let that fool ya, because the wave energy is weak (140) and conditions are just plain poor. From that first Friday all the way through to Saturday 18th July, every single session reads as “poor surf conditions” with scores of zero. There are no windows, no hidden gems. It’s a solid 16-day stretch of flat, choppy, or onshore junk.
The only moment that almost looks half-decent is Thursday 9th July around afternoon. We get an offshore breeze from the NE at 3 mph, giving us clean conditions at Mewslade Bay. But the swell is tiny – just 1ft from the west with a 9-second period, and combined energy is a pathetic 14. It’s barely a ripple. If you’re desperate for a float on a foamie, maybe, but don’t paddle out expecting waves.
Over the following days, we see some stronger winds – up to 19 mph from the west on Saturday 11th July afternoon, but it’s cross-onshore and lumpy. Swell heights rarely top 2ft, periods are generally short (5 to 10 seconds), and the direction is mostly WSW to W, which is fine for the break’s exposure, but the winds kill any chance of quality. The energy readings never break into three digits after the first couple of days, hovering in the teens and thirties – that’s weak, weak stuff.
By the second week, the pattern holds. Light rain and onshore winds on Tuesday 14th July bring a tiny 0.3ft swell with a very long 18-second period, but again, the wind and junk conditions ruin it. On Wednesday 15th July morning we get a light cross-shore breeze and 2ft of west swell with a 9-second period, but the cross-onshore picks up in the afternoon.
Nothing in this forecast stands out as a standout. Honestly, there’s no “best on offer” – it’s all poor. If you’re a beginner, the swell stays well under 5ft throughout, so it’s not dangerous, but it’s also not surfable in any meaningful way. This is one of those stretches where the coast just gives you nothing.
Hang in there, mates. Forecasts can always change.
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.
