The Lowdown

Alright, let’s break down what’s happening at H-Reef. The first week and a bit is a real bummer – persistent cross-shore winds and junk conditions just about every day. There’s swell, but the wind’s screwing it up. Poor surf all the way through to the start of September.

The first chance of anything decent is the morning of Wednesday the 2nd of September. Swell at 6ft from the ENE, period of 8 seconds, and combined energy at 515 (moderate). But it’s still cross-shore with a cross-chop – marginal at best. The afternoon picks up to 7ft, but same story.

The swell builds through Thursday the 3rd of September: 7ft in the morning from the E with a 10-second period, and energy jumps to 1006 (strong). The afternoon gets a real push – 8ft, a 13-second period (groundswell), and energy at 1702 (very strong). But again, the wind is cross-shore and the surface is chopped up. Just marginal.

Friday the 4th of September sees the swell peak around 8ft from the E, 12-second period, and energy at 1738 (very strong). But the afternoon goes cross-onshore and choppy – no good. The whole run is a write-off because of the wind.

The one and only standout is the morning of Thursday the 10th of September. The wind flips to a light S at 12 mph, going offshore, and the swell drops to a more workable 7ft from the NE with a 10-second period. Energy is at 823 (strong), and the forecast is calling for “very good surf conditions.” That’s the cleanest window of the whole outlook. With a southerly offshore and the NE swell lining up with the optimum NNE direction, this is your day. It’s over 5ft, so it’s not for beginners, but it’s still within reach for intermediate surfers. The afternoon holds with a cross-offshore from the ESE at 9 mph and clean surf, though the swell drops a little to 6ft.

After that, it’s back to cross-shore winds and dropping swell into the second week, and the surf fades to nothing by the 12th of September. So if you’re looking for a wave, you’re waiting until the 10th of September. That Thursday morning is the one to pencil in. The water temp is 80°F, which is about average for the time of year. It’s a long way out, so take it with a grain of salt, but as it stands, that’s your best shot.

Rusty.

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.
