The Lowdown

Alright folks, Rusty here. Let’s get into it for H-Reef. It’s a reef setup, exposed to the swell, and it’s got a nice optimum direction from the north-northeast. The water temp is sitting at 79°, which is about average for the time of year, nothing to write home about.

The next 16 days are a bit of a mixed bag, and I’ll be honest, the first week is a tough one to call good. We’ve got waves, but the wind is a constant problem. The swell shows up around Monday afternoon, July 27th, with a 7 ft swell from the east, but a 12 mph cross-onshore wind from the NE has it looking choppy and messy. The energy is moderate (1724 combined energy), but it’s not the clean stuff we want. The following days up to the 31st see the swell bumping up to 10 ft, but the wind stays cross or cross-on, keeping it lumpy. The period is short, around 8 to 14 seconds, so it’s not got that groundswell push. The best of this first week is probably Tuesday morning, July 28th, with a 10 ft east swell – that’s big, only for the experienced crew, but the wind is still cross-on, so it’s a grind.

Then we hit a dry patch. From Thursday, July 30th, through to August 5th, the forecasts are all scoring zero or one. The swell is still there, 5 ft to 8 ft, but the wind is a relentless cross-shore from the east at 16 to 19 mph. The energy is moderate (336 to 1109), but the conditions are just poor. The period drops to 8 seconds, so it’s windswell junk. Not the place to be.

Things start to look a little more promising around the second week. On August 4th, we see the period jump up to 11 seconds, which is a longer period groundswell. The swell is 5 ft from the east-northeast, but the wind is still cross. The energy is moderate (607). It’s still not perfect, but it’s a better shape. The standout, if I have to pick one, is likely the morning of August 9th. We’ve got a 7 ft swell from the north-east, with a 9-second period and moderate energy (760). The wind is still cross, but the direction is a little better. For a reef break, that north-east swell is a good match for the optimum direction. The crowds are “sometimes” at H-Reef, so you might get a few others out there, but it’s not a circus.

The very end of the window, August 11th, fades out with a small 4 ft swell and poor conditions. The energy drops to 267, so it’s a slow fade.

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.
