The Lowdown
Alright folks, Rusty here. Let's have a look at what we've got for Mewslade Bay over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough one. The whole 16-day window is a write-off for decent surf. There isn't a single recommendation in the forecast that’s worth paddling out for. From Thursday the 30th of July all the way through to Friday the 14th of August, every single session gets tagged as “poor surf conditions” with a score of zero. That’s a long, flat stretch.
The biggest problem is that there’s hardly any swell energy to speak of. The combined energy numbers are all tiny – most are under 30, and a few barely crack 40 (like 40 on Saturday the 1st of August morning). The waves themselves are tiny, mostly between 0.7ft and 3ft, and a lot of the time the wind is either cross or onshore, messing up what little bump there is. Even when the wind goes light or cross-offshore, like on the morning of Sunday the 2nd of August, the waves are only 1ft – not enough to get excited about.
Now, if you’re just desperate to get wet, there is a little glimmer on Wednesday morning the 12th of August. The wind is a clean cross-offshore from the NNW at 16 mph, and the swell is around 2ft from the WNW with a combined energy of 27. The period is short though, only 4 seconds, which means it’s just wind chop. It’ll be clean looking, but don’t expect any real power or shape. It’s a beach break, so with that short period and tiny size, it’s barely surfable.
The water temperature is sitting at a very unusual 68°F, which is about 8°F warmer than the long-term average for this time of year. You won’t need a thick wetsuit, that’s for sure.
Honestly, for this stretch, I’d leave the boards at home. The setup is so small and weak that if you’re really jonesing for a session, you’d be better off looking at a different spot, because Mewslade just isn’t offering anything.
Rusty.

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.
