Alright folks, Rusty here. Let’s have a look at what’s on the table for Mewslade Bay over the next couple of weeks.
Well, I gotta be straight with you – this is a tough one. The whole 16-day window is a bit of a write-off, to be honest. We’ve got a solid run of "poor surf conditions" across every single session. There’s no build-up, no pulse of real energy coming through that’s going to turn this place on. It’s just flat, or near enough, with tiny little waves that won’t give you anything to work with.
The first real opportunity doesn’t even feel like an opportunity. Tuesday the 7th is kicking things off with a tiny 1ft swell from the WSW, but that cross-shore and cross-on wind is just going to make it a choppy, messy affair. That 66° water temp is a huge talking point though – that’s a full 7° warmer than usual for this time of year. You could almost be in the tropics with that anomaly, but the surf just isn’t there to enjoy it.
The pattern stays the same all through the first week. A few mornings, like Thursday the 9th morning, we get a brief moment of glassy conditions, but with only 1ft of weak swell (combined energy of just 29), and a short period of 10 seconds, it’s barely a ripple. The best you can hope for is a tiny little waist-high slosh on a clean face.
Now, toward the end of the window, around Saturday the 18th afternoon, we actually get another glassy spell – zero wind, calm conditions. The swell is still pitiful though: 1ft from the SW with a period of just 7 seconds. The energy is tiny (26). So, it’s beautiful water, but no push behind it. Sunday the 19th morning is the same story: dead calm, glassy, but only 1ft from the WSW.
Honestly, the most notable thing in this whole forecast is the water temperature anomaly. That’s the real headline, not the surf. For actual waves, you’re better off finding a different hobby for a week or two. There is no standout, there is no best on offer. It’s a waiting game.
Stay patient.
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.
