The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next 16 days.
Firstly, I gotta be straight with you – the forecast for H-Reef is pretty grim for a long stretch. The first recommendation for decent surf doesn't show up until the morning of Monday, 23rd September, and even then it's only a marginal call. That’s a solid gap of nearly two weeks from the start of the period with nothing worth paddling out for. A lot of poor surf conditions, cross-shore winds, and choppy, messy lineups.
Let’s talk about that one period that might actually get the heart beating a little. The standout window is centered around the morning of Thursday, 24th September. We’ve got a solid 6 ft swell rolling in from ENE, paired with a decent 9-second period. The combined energy of all swells directed here is strong (776), so there’s real power in the water. The wind is light and cross-shore – just a light breeze – which will keep the surface pretty clean with only small crossing wind ripples. That’s a big positive. The waves will be on the bigger side for a reef break like H-Reef, so this is not a day for beginners. Over 5 ft is pushing it for the groms, and with that energy, you’ll need your wits about you. It’s an advanced spot anyway, so that suits the crew who paddle out there.
The water temperature is sitting at a very warm 80°F, which is bang on average for this time of year – no weird anomalies here, just your usual tropical bath water.
The only other sniff of something rideable is the morning of Wednesday, 23rd September, with a 8 ft swell from E (870 energy), but the wind is cross-onshore which kills the quality. The afternoon of the 24th also shows some marginal potential with the same 7 ft ENE swell (783 energy) but a gentle cross-shore breeze and risk of thunderstorms. It’s there if you’re desperate, but the Thursday morning window is the one to aim for.
Honestly, for H-Reef, it’s a lot of waiting. The first week and a half is a write-off. Keep an eye on the forecasts though – these things can shift. But if you’re locking in a date, make it the morning of Thursday, 24th September. That’s the only true standout in this whole 16-day run.
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.
