The Lowdown
Alright folks, Rusty here. Let’s break down the next 16 days for this patch of coast. I’ve gotta be straight with you – it’s a grim outlook. We’re looking at a long, dry spell with barely a ripple on offer.
Honestly, there’s not a single standout session in the whole window. The first real chance of any wave energy doesn’t show until Tuesday morning, July 21st, but even then it’s barely a pulse. We’re talking about a 2 ft swell from the SE with a short period of 7 seconds, and combined wave energy is a weak 27. The wind is a cross-off from the East at 15 mph, which keeps the surface clean, but that swell is just too small and weak to get excited about. It’s a beginner-only day at best, and even then, it’s a struggle.
For the rest of the period, it’s a total write-off. The forecast shows days and days of nothing – zero swell energy. There are a few tiny blips later on, like a 3 ft ESE swell on Thursday afternoon, July 23rd, but with a 7-second period, it’s gutless. The wind stays in that cross-off zone, mostly from the East or ENE, blowing at 15 to 22 mph, which is a fresh breeze. It keeps the ocean looking clean, but there’s nothing to ride.
The water temperature sits at 83°F, which is about 0.5°F above normal for this time of year, so it’s average – you won’t need a wetsuit.
Because this is a sheltered reef break that rarely breaks, it’s not a surprise to see a blank run like this. It’s pretty normal for the area. With such a long gap of no surf, and the tiny, weak swells we do get, the setup honestly looks more interesting for kite surfing than paddle surfing. You’d be better off leaving the board at home.
Rusty.

Information about the Thunder Surf forecast
The above surf forecast table for Thunder provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Thunder can be found by selecting the local surf guide option on the grey menu. Our Thunder 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 (Thunder) 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 Thunder 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.
