The Lowdown
Alright, Rusty here. Let's break down what's headed our way for the next couple of weeks. Gotta be honest, it's a bit of a waiting game with a whole lot of chop in between.
The big problem is the wind. For almost the entire first week and a half, we're looking at a steady easterly breeze blowing at 15 to 30 km/h, creating a constant cross-shore mess on H-Reef. The swell does come up, but the quality is just not there. We're seeing moderate wave energy, with values mostly between 100 and 800, but it's all being ruined by the bump.
Starting Monday afternoon, September 14th, we've got small, weak swell around 2 ft from the NE, but it's cross-on and choppy. That's the story for the next ten days. Even when the swell builds to 6 ft by Thursday, September 17th, and climbs further to over 8 ft by Tuesday, September 22nd, with wave energy hitting a strong 1171, that wind doesn't let up. The water temp is around 80°F, which is about what you'd expect for this time of year, so nothing unusual there.
The one bright spot, and the only real standout, looks to be around Tuesday, September 29th. Finally, the wind drops off. On Tuesday morning, we're down to a light 10 km/h breeze from the east, and by the afternoon it swings to a light ESE cross-off. That means clean, workable conditions. The swell will be around 5 ft from the NNE, right in the sweet spot for H-Reef, with a short period of 8 seconds and a moderate wave energy of 495 to 543. It won't be pumping, but it'll be the cleanest surf of the entire 16-day window. Just be aware, H-Reef is a reef break, so with that shorter period it might be a little tricky, but that clean afternoon wind is your best bet.
So yeah, there's a long stretch of bumpy, frustrating surf ahead. But if you can be patient, Tuesday, September 29th is the day to circle. It's a way off, so don't book the time off just yet, but that's the one session with potential.

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.
