The Lowdown
Alright, Rusty here. Let’s break down what’s coming for Wamberal Beach.
Water temp is about 64°F, which is roughly 1°F cooler than average for this time of year. Nothing wild, just a little nippy, so you’ll want a good wetsuit.
The first week and a half is pretty flat. There’s a long stretch of small, weak swell with combined energy readings mostly under 100 (weak wave energy), and the wind is often a hassle. There are a few glassy moments, like Wednesday morning the 19th with 2ft of ESE swell and a 10-second period, but the waves are just too ordinary to get excited about. The energy is only 181 (moderate wave energy). Not worth your time.
The big one shows up on Sunday the 30th of August. That morning, we’ve got a solid 8ft swell from the SSE, with a very long period of 18 seconds – that’s proper groundswell. The combined energy is a massive 5494 (very strong wave energy). The wind is light and cross-off from the SSW, keeping it clean. This is for experts only; 8ft with that kind of power is serious. The long period means it’ll be fast and powerful, better suited to a reef or point, but Wamberal is a beach break so it might be a bit straight and dumpy. Still, this is the standout.
The next morning, Monday the 31st of August, is also a good one. The swell drops to 6ft from the SSE, still a solid 12-second period, and the wind is glassy – dead calm. Combined energy is 915 (strong wave energy). That’s a much more manageable size for a strong crew, and with glassy conditions, it’ll be clean and fun. The morning is the pick.
Tuesday the 1st of September morning has a smaller 4ft SSE swell, 10-second period, and glassy conditions with 318 combined energy (moderate wave energy). A decent option for a quieter session, but not the main event.
So to wrap it up: the first week and a half is a dud. The best bets are Sunday the 30th of August morning for the experts, and Monday the 31st of August morning for the strong intermediates. The rest is small, choppy, or just plain ordinary.
Rusty.

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

If you surf the same spot (Wamberal Beach) 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 Wamberal Beach 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.
