Table - best surf conditions forecast for Thunder over the next 16 days.
Alright, this is Rusty. Let me level with you right off the bat: the next two weeks at Thunder (located in a very sheltered nook of its region) are looking grim. For a spot that rarely breaks and has a history of being super fickle, the next 16 days are pretty much a write-off. The ocean is just not playing ball.
Looking at the pattern, from Saturday the 11th of July right through to Wednesday the 23rd of July, there’s simply no swell to speak of. That’s a solid twelve-day gap with no recommendations. The water temperature is sitting at 82°F with an anomaly of 0.36°F, so it’s about average for the time of year—warm, but that’s about all it’s got going for it. The wind is hanging in from the ENE and E, solid cross-off at 16 to 22 mph the whole way through. It’s clean enough, but there’s nothing to ride. If you paddle out, you’ll just be floating.
Things get interesting on the 24th of July, Friday afternoon. Suddenly we see a solid 8 ft swell from the ESE with a period of 9 seconds. The combined energy is huge at (1159), which is strong, but that’s a mixed bag. For a reef break like Thunder, that size combined with a short period is going to be a bit of a mess. It’s marginal and the tide likely won’t help. That’s expert-level size, so if you’re a beginner, stay well away. Also, with crowds listed as “sometimes,” you might have a few heads out, but the quality will be rough.
Saturday the 25th and Sunday the 26th of July are back to weak, tiny waves (0.3 ft from the SE) and poor conditions. The 26th has a period of just 8 seconds, which is short and weak.
So, if I had to pick the one and only standout in this entire 16-day window—and it’s a weak one—it’s that Friday afternoon on the 24th of July. It’s the only day with any real size and energy, but with the short period and the cross-off wind at 16 mph, don’t expect perfection. It’s more one for the experienced crew who are desperate. For everyone else, this is a long, flat stretch. It’s normal for an area when a break is this inconsistent.
Stay tuned, forecasts change, but right now? Not much happening.
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.
