The Lowdown
Alright, mate, let’s boil it down. Looking ahead 16 days, Thunder gets a zero across the board. The first week is a total washout – no swell, and the wind is ripping from the ENE at 22–25 mph. No wave energy directed here.
Friday 14th through Sunday 17th: forget it. Flat calm surfaces but nothing to surf. Monday 18th shows a tiny 0.6ft SE swell, but period is only 8 seconds, combined energy is weak (54), and it’s still a zero score. That pattern hangs around – 0.6ft to 0.9ft, 8-second period, all rated poor. The combined energy gets into moderate territory on Thursday 20th (122) and again on Monday 24th (155), but still a zero.
This reef hardly ever breaks, and it wants ENE swell – all we’re getting is SE. Wind stays mostly cross-offshore from the E, so it’s clean, but the waves are wrong. The only possible standout energy-wise is Monday 24th with 0.9ft at 8 seconds and 155 combined energy, but it’s still a zero.
No good options here. This spot is known for long quiet spells, so this is normal. Forecasts can flip, but as it sits, there’s nothing to ride.

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.
