The Lowdown
G’day, Rusty here. Look, I’m gonna be straight with you – the next couple of weeks are a bit of a mixed bag for H-Reef. We’ve got some size coming, but the wind is mostly a pain. It’s not a write-off, but you’ll need to pick your moments. The water temp is sitting at 80°, which is about average for this time of year, so don’t stress about a wetsuit.
Right now, through to the end of August and into the first few days of September, we’re seeing a stubborn cross-shore breeze from the ENE, mostly around 12 to 16 mph. That’s putting a real chop on the surface. Swell heights are bouncing between 4 ft and 6 ft, with short, weak periods of just 7 to 8 seconds, and the energy is moderate at best – think values like 207 up to 504 on the energy scale. The surf quality is simply poor. Don’t get too excited yet.
Things start to change on Tuesday, 1st of September. The swell picks up a notch, hitting 6 ft from the ENE, and the wave energy climbs into strong territory at 504. But the cross-shore wind is still there, and the reports say “marginal surf forecast or questionable tide conditions.” It’s a tease, not a goer.
Now, the real stand out – and the only one I’d mark on your calendar – is Thursday morning, 3rd of September. We get a solid 7 ft swell coming from the E, and the period stretches out to 11 seconds. That’s a proper groundswell. The energy is very strong at 1076. The wind is still cross from the ENE at 12 mph, which isn’t perfect, but it’s manageable. The reports call it “marginal,” but given the size and the longer period, this is the best looking window for a paddle. Short period swells are better here; long period can make beach breaks straighten out, but H-Reef being a reef break should handle it. It’s an advanced spot, and it’s fairly consistent when there’s swell. Expect some company though – crowds are noted as “sometimes” here. The swell direction is ENE, right in the ballpark of the optimum NNE for this break, so it’s working.
After that, the swell hangs in the 7 ft to 8 ft range through the first week of September, with periods of 11-12 seconds, so plenty of energy in the water (reading 1330 to 1606). But the wind remains a stubborn cross or cross-onshore, and the reports keep saying “poor surf conditions” or “marginal.” For the bigger days over 8 ft, that’s expert territory only, and with the chop, it’s more of a battle than a treat. If that ENE wind keeps up on the 4th of September afternoon at 16 mph cross-on, this setup looks more interesting for kite surfing than paddle surfing.
We get a brief glimmer on Friday, 11th of September – a window with glassy conditions in the morning thanks to a light SSE breeze, and offshore wind in the afternoon from the S at only 6 mph. The swell is 6 ft to 6 ft from the E, but the period drops back to a weak 7 seconds. It’ll be clean, but it’s not the same quality as that groundswell earlier. That’s a session for a fun little board, not a step-up.
So, the pick of the 16 days is the morning of Thursday, 3rd of September. The rest of the forecast is either choppy, messy, or too big with bad wind. Keep an eye on it, because sometimes a little luck can turn that cross-shore into a smooth one, but as it stands, that Thursday is your best bet.
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.
