Table - best surf conditions forecast for Thunder over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this one’s a tough read. We’re looking at a full 16-day window, and honestly, there’s barely a ripple to get excited about. The whole forecast period is a long, flat spell with no real swell to speak of. The only wave we ever see is a tiny 0.3 ft SE swell on the very last day, and it’s barely a blip. The rest of the time, the combined energy is sitting at 0 – that’s as dead as it gets.
The only spot on the map is Thunder, a sheltered reef break that rarely breaks at the best of times. It’s an intermediate-level wave, but with no swell, it’s just not happening. The water temperature is sitting at 83°, which is about average for the time of year, so that’s not the problem.
We’ll run through the dates, but it’s a short story. Starting Wednesday, July 8th, right through to Wednesday, July 23rd, it’s the same story: flat. Day after day of cross-off winds – mostly from the E or ENE at 15 to 22 mph – and a sky that can’t make up its mind between clear, cloudy, or the odd risk of a thunderstorm. There’s zero surf. The tables are clean, but because there’s no wave, “clean” doesn’t mean a thing. The only standout here is how long this dry spell goes on.
Come Thursday, July 23rd afternoon, we finally see a pulse: that 0.3 ft SE swell, with a period of 8 seconds and combined energy of just 3. That’s so weak it’s basically a lake ripple. The wind is ENE around 16 mph, so it’s cross-off. For a break that’s rare to break and this sheltered, it’s not going to produce anything rideable for a paddle surfer. If you’re a kite surfer, maybe, just maybe, you could get a skid on that, but for a surfboard? Forget it.
So, the honest truth: there are no good surf options in the entire 16-day window. This is a total blank run. For a spot like Thunder, which is rarely consistent anyway, this kind of dead stretch is more normal than you’d hope. It’s a bummer, but sometimes the ocean just takes a holiday. Keep your board waxed, because forecasts can change, but right now, don’t hold your breath.
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.
