The Lowdown
Alright, Rusty here. Let's be straight with you—this one's a tough read. We're looking at Thunder, a sheltered reef that rarely breaks, and over the next 16 days, it just isn't cooperating. The whole period's a write-off for surf. The forecast shows nothing but poor surf conditions from August 26th right through to September 10th. The swell's tiny, barely a ripple, with heights mostly between 0.7 ft and 3.6 ft out of the southeast, and the combined energy barely gets a pulse—hitting only 171 at its peak on the 31st of August afternoon. That's weak, mate. The wind's hammering out of the east at 15-22 mph practically the whole time, keeping things cross-offshore and messy. A few afternoons, like the 29th of August, show offshore flow, but with next-to-no swell, it's a flat, glassy lake with nothing to ride.
This break is inconsistent at the best of times, and this 16-day window is a complete blank run. For this sheltered spot, that's not unusual—it can stay quiet for long stretches. Honestly, with the combination of tiny swell, poor quality, and steady easterly breeze, this setup looks more interesting for kite surfing than paddle surfing. Don't hold your breath. Keep an eye on the charts—things can change.

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.
