The Lowdown
Alright, I’ll be straight with you – the next couple of weeks look pretty dead.
The first surf worth mentioning is on July 20th, but it’s a dud. The water temp is 28° – about normal for the season – but the waves just aren’t there.
The only spot in the forecast is Thunder, a reef that “rarely breaks.” It’s sheltered and likes swell from the ENE, but almost every day from July 20th to August 4th has cross-off winds out of the east at 15 to 19 mph. The combined swell energy never tops 71 (weak), and the biggest wave is just 3 ft on July 26th Sunday afternoon, with a short 8-second period.
Every single reading says “poor surf conditions.” The swell never gets above 3 ft, the period rarely hits 9 seconds, and the wind never turns offshore. For a reef that rarely breaks, this is a total bust.
If you’re thinking of surfing, don’t bother. This setup is so weak and wind-blown it’s better suited for kite surfing. The waves are tiny, the wind is constant, and the break is inconsistent. It’s not unusual for this area to go quiet like this, and this is one of those quiet spells.
Nothing to get excited about. No standout days. Just a 16-day stretch of flatness. Forecasts can change, but right now? Not a chance.

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.
