Table - best surf conditions forecast for Thunder over the next 16 days.
The Lowdown
Alright, let’s talk surf. The outlook for the next 16 days is pretty flat, to be honest. The only break on the map is Thunder, and it’s a reef that rarely breaks, sheltered from most swell. Water temperature is about what you’d expect for this time of year, nothing wild.
We kick off on Wednesday, July 15, with a tiny 0.3ft wave from the southeast, but it’s got a long 13-second period. The energy is weak (7), and the wind is a cross-off breeze out of the east at 15 mph. Clean, but you’d be hard-pressed to catch anything.
Thursday, July 16, sees a slight bump to 1ft in the morning and 2ft in the afternoon, both from the east-southeast, but the period drops to 7-8 seconds. Energy is still low (28 and 41). Wind stays moderate cross-off.
From Friday, July 17, through Monday, July 20, it’s totally flat. No swell, just clean water and fresh cross-off winds. A four-day gap of nothing.
Tuesday, July 21, a 0.7ft wave shows up in the morning from the east-southeast (8 seconds, 7 energy), but it’s gone by the afternoon. Wednesday, July 22, brings a 1ft wave in the morning and 2ft in the afternoon, both from the southeast, short period, low energy.
Thursday, July 23, has a 2ft wave in the morning from the southeast (8 seconds, 51 energy) with a risk of thunderstorms, then the afternoon goes flat. Friday, July 24, offers a 2ft wave from the east-southeast in the morning (8 seconds, 41 energy) and a 2ft wave from the southeast in the afternoon (8 seconds, 30 energy). Still poor.
The weekend of July 25 and 26 is tiny, with 1ft to 2ft waves, short period, low energy. Then another flat spell from Monday, July 27, through Tuesday morning, July 28, before a few more 1ft pulses from the east-southeast on Tuesday afternoon through Wednesday, July 29. By Thursday, July 30, it’s flat again.
Thunder is a rare-breaks reef, and this whole 16-day window is a long run of tiny waves and zeros. There’s no standout. The best you’ll see is the afternoon of Thursday, July 23, with a 2ft wave and 51 energy, but it’s still poor. For a proper surf, you’re out of luck. This kind of quiet stretch is pretty normal for the area.
Hang in there, and keep an eye on the forecast – things can turn around.

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.
