The Lowdown
Alright folks, Rusty here. Let's take a look at what's on offer for H-Reef over this stretch.
Honestly, it’s a tough run for the next fortnight or so for H-Reef. The start of the period is a write-off. We’ve got a couple of weeks with nothing but poor surf conditions and no real chance of a decent wave. The wind is mostly cross or cross-onshore from the east, and it’s never light enough to clean things up. For the first week and a half, the swell is small and weak, often under 3 ft, and what little energy there is gets chopped up. It’s a frustrating gap if you're keen for a paddle.
Things start to look a little more interesting around Thursday the 27th of August. That’s when we see the swell bump up. On the 28th, you’re looking at a solid 8 ft of easterly swell, with a period of 9 seconds. The combined wave energy is strong, hitting around 1211 (strong to very strong) on Friday morning. But here’s the catch – the wind is still cross-shore from the ENE at 12-15 mph, keeping things lumpy. The surf forecast notes it as "marginal," which is fair. It’s not clean, but for the experienced crew, there’ll be some size and push. Given the swell is over 8 ft, this is strictly for the experts only. The optimum swell direction for H-Reef is from the NNE, so that east swell is a bit off-angle, but at this size, it’ll still wrap in.
The real standout, if you can wait, is Monday the 31st of August. We’ve got a long-period groundswell rolling in – 7 ft from the east with a period of 13 seconds. That’s a very long period, which means proper energy and well-shaped waves. The combined energy is pumping at 1685 (very strong). The wind finally drops to a gentle breeze, just 9 mph from the ENE, and it’s cross-shore. That will give you manageable, slight cross-chop, which is about as good as you’re going to get here in this window. For a reef setup like H-Reef, that long-period swell will be fantastic, with long lines and plenty of power. It’s a promising outlook, but given it’s over a week away, don’t nail your plans to it just yet. Crowds are *sometimes* a thing here, so with this kind of quality on the horizon, expect some company.
Stay salty.

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.
