The Lowdown
Alright, Rusty here again. Let’s run through the same outlook for H-Reef but in feet and miles per hour.
Water temp is about 80°, right where it should be for this time of year.
The first week, from August 26th through September 1st, is nothing but poor surf. The wind is cross-shore, blowing 12 to 16 mph, and the swell is short period, around 7 seconds, from the east. The combined energy is weak to moderate, between 182 and 442. The reef isn’t getting what it needs. It’s all chop and cross-chop.
Things get slightly better from September 2nd into the morning of September 5th. The swell comes up a bit, with wave heights around 5 to 6 feet, period stretching to 9 to 10 seconds, and combined energy climbing into the 400s to 600s. The wind stays cross-shore, around 9 to 12 mph, so it’s still not clean, but there’s more energy in the water. Just barely marginal.
Then, from September 6th on, it drops off again. Wave heights fall to 4 to 5 feet, energy drops to the 300s, and the wind picks up. By September 8th and 9th, we’ve got rain showers and a fresh breeze up to 18 mph, making the surface lumpy. The only glimmer is on September 10th afternoon, when the swell direction swings to the northeast, period hits 11 seconds, and energy jumps to 590. But it’s still marginal, and there’s a risk of thunderstorms.
The best single moment? Wednesday morning, September 2nd. Swell around 6 feet from the east-northeast, period 9 seconds, energy 579. Wind is a moderate cross-shore. For an advanced reef break, that’s your best bet, but it’s still not classic.
Bottom line: the next 16 days are mostly flat and poor. Long gaps with no good surf. If you’re a die-hard, maybe that September 2nd morning gives you a couple of waves. Otherwise, leave the board in the car.
Rusty, out.

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.
