The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what’s ahead for H-Reef. It’s a tricky outlook, to be honest. We’re looking at a solid 16-day window, but the first week and a bit is a write-off for any quality surfing. We’ve got a lot of wind and messy conditions making it hard to find a clean wave.
The real story is the arrival of a decent swell late in the second week. The water temp is about average for the time of year, so nothing wild there.
We start off on Friday, 14 August with a clean-looking sky but a stiff cross-shore wind from the ENE at 15 mph. The swell is already there, around 7 ft to 8 ft, but it’s a messy, short-period E swell (9-11 seconds). The wave energy is moderate at 799 but jumps to a strong 1515 by the afternoon. Don’t be fooled by the numbers – the wind is trashing it. The surf quality is poor, and it’s not going to be a good session. If you’re an expert, you might find something, but it’s not for the faint of heart.
Through the weekend, Saturday, 15 August and Sunday, 16 August, the wind ramps up even more, with gusts hitting 25 mph out of the E. The swell gets bigger, topping out at 12 ft with a very strong wave energy of 3025. This is big, powerful, and messy. It’s only for serious experts, and even then, the conditions are more suited to a kite than a paddle. The period is still short for the size, so it’s just a lot of lumpy, choppy water. Sunday morning offers a bit of a reprieve as the wind shifts to a cross-off from the ESE at 19 mph, which cleans things up a little, but the swell is still 12 ft. It’s a marginal call.
The beginning of the following week, Monday 17 August through to Thursday 21 August, sees the swell drop steadily. The wind stays a cross-shore from the E or ENE, but it’s lighter, around 9-12 mph. The wave energy drops to 123-238, which is weak. The swell is small, around 3 ft to 5 ft, and still short-period. It’s just not worth the paddle. The surf quality is consistently poor.
There’s a lull in the action for several days after that. The 22nd through the 26th of August offers nothing but small, weak, and wind-affected waves. The wind remains a persistent cross-shore. The surf quality is rated as poor or marginal at best. It’s a quiet stretch.
Now, here’s the one to watch. We finish the window with a pulse. Thursday, 27 August morning shows a building 8 ft E swell with a 9-second period, pushing moderate wave energy at 845. The wind is still cross-shore from the E at 15 mph, so it’s not perfect, but the energy is there. The real standout is Friday, 28 August. The morning session shows a 10 ft swell from the E with a 10-second period, and the wave energy is strong at 1715. The wind is lighter, from the ENE at 12 mph, but still cross-shore. It’s a marginal forecast, but if it cleans up, this is the best window for a paddle. The 10 ft size is expert territory, but the longer period (10 seconds) means better-shaped waves and more energy. The direction is a touch off the optimum for H-Reef (which likes NNE), but it’s the best we’ve got.
Saturday, 29 August morning closes the window with a smaller 5 ft NE swell, 8-second period, and a lighter ENE breeze at 9 mph. The energy is moderate at 647. It’s a marginal call, but a much more manageable size.
Highlight: The standout is the Friday, 28 August morning session. The 10 ft E swell with strong energy is the biggest, most powerful event of the forecast. The lighter wind makes it a better bet than the earlier big swells, but it’s still a cross-shore, so don’t expect perfection. For those who can handle the size, it’s the only real moment of quality on offer.
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.
