The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got H-Reef on the radar, and I’ll be real with you – the first week and a half is a bit of a write-off. The swell is coming in from the ENE and E, but it’s a short, choppy period with cross-shore winds that just won’t let the place clean up. The reef is exposed, but the conditions are making it a mess. Moderate cross-chop and lumpy stuff is all we’re seeing. The combined wave energy is moderate, but it’s not doing you any favors with the crummy wind. Water temp is sitting at 80°F with a normal anomaly of -0.5°F, so that’s about average for this time of year – nothing to complain about there.
We’re looking at a solid gap of no good surf from Wednesday, September 9th, all the way through to the morning of Sunday, September 20th. That’s a long dry spell. The swell climbs a bit, with some 6 ft to 7 ft, but the wind stays cross and the period is short (7-8 seconds). Not worth paddling out.
Now, hold on to your board. The real standout kicks off on Monday, September 21st. We’ve got a proper groundswell arriving. The swell direction is from the E, and the period jumps to 14 seconds – that’s very long period energy. The combined wave energy shoots up to 1097, which is strong. The swell is 4 ft in the morning, but it’s paired with a moderate cross-shore breeze. The afternoon bumps up to 8 ft and the energy hits 1998. That’s a lot of juice. The wind is still cross, but with that long period, the reef should handle it. This is a big, powerful swell. For the advanced crew, this is going to be a mission. The break is fairly consistent, but it’s a reef, so you need to know what you’re doing. The optimum swell direction is NNE, and we’re getting E, so it’s not a perfect match, but the sheer size and period will still produce some proper waves. Crowds are possible here – it’s a spot that can get busy when it’s on.
The rest of the week into September 24th keeps the goods coming. Swells hold around 7 ft to 8 ft, with periods dropping from 13 seconds down to 11 seconds. The energy stays strong. The wind stays cross, but it’s manageable. The Thursday morning and afternoon on the 24th have 8 ft and 8 ft swells, with the energy at 1702 and 1756. That’s solid, but it’s getting big – over 8 ft, so this is expert territory only. The quality is still marginal on the scores, but the raw power is there.
If you’re a beginner, stay away from this whole period – it’s too big and too heavy. For the experienced crew, the window from September 21st to the 24th is your best bet. The early part of that window, with the 14-second period, is the real highlight. The waves will have shape and power, but the long period might make it a bit straight at the reef, so you’ll be hunting for the right takeoff. The wind is never truly offshore, but it’s cross, which is workable. The crowds are something to watch for – it’s a spot that sees its share of locals when it’s pumping.
So, to sum it up: the first 12 days are a no-go. Then the 21st through the 24th bring the real deal. The morning of the 21st is the sharpest, most promising call, but it’s a long-range forecast, so keep an eye on it. The swell is big, the energy is huge, and if you’re a competent surfer, you’ll be amped.
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.
