The Lowdown
Alright, Rusty here again. Let's talk about Mewslade Bay in feet and degrees. It's going to be a quiet couple of weeks, I won't sugarcoat it.
We've got a big stretch of time coming up where you'll be lucky to find a wave worth paddling for. Starting now and running through the first week of August, it's pretty flat. The water temp is just normal for this time of year, nothing to write home about. With next to no swell and wind coming from all angles, it's just a glassy but empty ocean.
The only real glimmer of hope comes on Monday, August 3rd. A little pulse of energy rolls in – about 3ft from the WSW with a period of 9 seconds. The combined energy is still weak at 68, but it's something. The morning session looks the cleanest with a light east wind. You'll get a few small, rideable waves, but it's strictly a small-wave board day. The afternoon gets a bit messy with a cross-shore wind from the WNW. That's your one and only chance for a while.
After that, it's back to the doldrums. From the afternoon of the 3rd right through, the waves shrink back down to a foot or less. We get a couple of glassy afternoons, like on the 4th of August, but with waves at just 1ft, it's barely a bump. This flatness is the story of the whole second week, from the 6th all the way to the 13th of August. The swell just vanishes – we're talking ankle-biters at 0.5ft. The wind turns offshore and clean at times, but you need water to surf. It's just a long, flat, quiet spell. Not much else to say, I'm afraid.
Rusty, signing off.

A general guide to surfing at Mewslade Bay can be found by selecting the local surf guide option on the grey menu.

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.
