The Lowdown

Alright folks, Rusty here. Let’s tell it straight: this next sixteen days is a tough one for Mewslade Bay. The whole run is a long, dry spell – we’re talking flat, onshore junk for nearly the first week. There’s nothing to get excited about.

The forecast shows a real gap with no decent surf until the start of August. From Friday the 24th of July right through to the end of the month, it’s tiny, choppy, and cross-on. The 26th of July bumps up a bit, with a 5 ft to 5 ft WNW swell, but the wind is hacking from the WNW at 18 mph, making a lumpy mess. That’s kite-surfing wind, not point-surfing wind. The water temp is a notable 69°F, which is much warmer than normal for this time of year, so you’ll be warm in the water, but that’s the only good thing.

Then, on Saturday the 1st of August, we finally get a window. The morning is the standout. We’ve got a solid 6 ft swell from the WSW, with a 12-second period – that’s a proper groundswell with some energy behind it (748 combined energy). The wind is dead calm, glassy. That’s as good as it gets. This is a rare, solid window of clean surf. The swell direction is right in the sweet spot for Mewslade’s SW exposure. It’s only for the morning, though, as the wind swings onshore by the afternoon. The crowds are described as “sometimes,” so it could get a little busy for that morning session, but it’ll be worth it.

After that, we’re back to onshore chop. The 5th of August sees a bigger 7 ft swell from the WSW, but the period is only 8 seconds – short-period wind swell – and the wind is a 18 mph cross-onshore, making it a lumpy, blown-out mess. That size is only for experts, and even then, the wind will ruin it. The setup is more interesting for kite surfing than paddle surfing.

The Bottom Line: The only true, clear standout is the morning of Saturday the 1st of August. Get on it early. The rest of the window is a write-off.

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.
