The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks. Straight up, I gotta be honest with ya – it’s a bleak picture. The only spot on the radar is Thunder, a rarely-breaks reef setup, and even that has almost nothing going for it. We're looking at a long, dry spell, so if you've got a kite, that might be your best bet.
First up, Wednesday the 29th. We've got a tiny pulse of 0.7ft from the ESE, period a short 8 seconds. Combined energy is a weak 7, barely a ripple. The water is sitting at 84°, which is pretty much average for this time of year. Wind is howling out of the east at 22 mph, cross-offshore, which cleans it up but that tiny swell won't stand a chance. It's marked as poor surf, and honestly, for a paddle surfer, there's nothing here.
That little blip disappears immediately. From Thursday the 30th all the way through to Thursday the 13th of August, there is not a single recommendable wave. Most days show zero combined energy, and the few that show a little bump – like Friday afternoon the 31st with a 2ft swell (combined energy 57) or the 3ft on Saturday morning August 1st (combined energy 91) – are all still rated as poor surf conditions. The wind stays relentless from the east, mostly 16 to 22 mph, keeping the surface clean but the wave quality is just not there for this sheltered reef. The swell direction from the SE and period around 7-8 seconds is weak and disorganised.
The biggest we see is a 3ft ESE swell on the afternoon of Friday the 7th of August, with combined energy climbing to 114 – that's moderate juice. But it's still a short 7-second period, the wind is a moderate 16 mph cross-offshore, and the call is “poor surf conditions.” It’s just not coming together at Thunder.
So, the outlook is rough. Thunder hardly ever breaks as it is, and even in this 16-day window, there's virtually no quality on offer. If you're desperate to get wet, maybe a bigger swell day down the line might kick up something rideable, but for now, it’s a clean, blown-out blank. Don't hold your breath.

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.
