The Lowdown
Alright, let’s have a look at what we’ve got coming up. The next few days are pretty average, but there’s a window that’s gonna make it all worthwhile.
Right now, we’re in a bit of a flat spell. The forecast kicks off with H-Reef on the 6th and 7th of September, but I wouldn’t even bother paddling out. It’s got size—around 8 ft to 8 ft—but it’s messy. Cross-shore wind from the east at 16 mph, and the wave comment just says “marginal surf” with scores of 1. It’s one of those where you’re better off waiting. The combined energy is up there, around 1550-1600 (strong), but it’s not clean enough to enjoy. No standouts there.
Then we hit the 8th of September. Now this is what we’ve been waiting for. Tuesday morning at H-Reef is the clear highlight. The wind swings to a light SSE at 3 mph, going cross-offshore, and that’s gonna leave the surface glassy and clean. Swell drops a bit to 6 ft from the ENE with an 11-second period (decent groundswell), and the combined energy is still moderate to strong at 1018. The wave comment says “excellent surf conditions for experienced surfers.” That’s because at 6 ft, it’s pushing into the bigger range, but for those who know what they’re doing, it’s gonna be firing. The swell direction (ENE) is pretty close to the optimum NNE, so it’ll wrap in nicely. Tuesday afternoon is also good with a 6 ft, clean, and a light breeze, but the morning is the pick.
After that, it’s back to average. From Wednesday the 9th through to the end of the outlook, it’s mostly poor surf conditions. Swell drops right off, periods get short and choppy, and the wind stays cross or cross-on. There’s a brief uptick on the 11th with 5 ft and a 12-second period, but the wind is still cross at 12 mph, so it’s just not worth it. The energy drops to moderate or weak, and the comments say “poor” or “marginal.” It’s a long stretch of nothing special.
So, if you’re looking for the one true standout, it’s Tuesday 8th September morning at H-Reef. Clean, solid groundswell, good direction, and light offshore wind. That’s your window. After that, you’re waiting a long time.

Information about the H-Reef Surf forecast
The above surf forecast table for H-Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at H-Reef can be found by selecting the local surf guide option on the grey menu. Our H-Reef 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 (H-Reef) 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 H-Reef 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.
