The Lowdown
Alright, let’s get into it.
Look, the next week and a half is going to be a bit of a grind for waves at H-Reef. The energy is there, but the wind and the swell direction are just messing things up for us. We’re looking at a long stretch of cross-shore and cross-onshore winds, which is going to keep things chopped up and messy. The swell direction is coming more from the E and ENE, which is a bit off for this spot, and it’s making for some pretty poor surf.
The first real surfable day isn’t until Wednesday the 23rd. That’s when we finally see conditions come together. A bigger swell fills in, and the wind switches to a light ESE cross-offshore. That’s what we need. The morning of the 23rd is your standout – that’s the best this spot is going to see in this whole stretch. We’re talking 10ft of east swell with a 10-second period, and the combined energy is strong (1643). The wind is only 3 mph, which is basically glass. It’s going to be clean and lined up. It won’t be one for beginners – it’s a solid, powerful wave.
The afternoon of the 23rd is still decent, with a 10ft swell but the wind picks up a bit to 9 mph from the ESE, staying cross-offshore. Still clean, but the morning is the pick. This is an advanced reef, and it’s fairly consistent, so if you’ve got the skill, don’t sleep on it.
After that, the winds turn onshore again from the WNW and NW on the 24th, which is no good. There’s still a big 8ft swell running, but with that cross-onshore wind, it's gonna be a mess. The 25th does offer a glimmer – the afternoon shows a glassy wind and a 7ft swell from the east. That could be a fun, more manageable size, but it's not the same quality as the 23rd.
Beyond that, it’s a steady decline back into that cross-shore chop with average energy. It’s a long second week, honestly. The first week is a no-go. The only real window you need to care about is the morning of Wednesday the 23rd.
The water temp on the 15th is 80° and that’s about normal for this time of year, so no surprises there. It’ll feel fine in boardies or a shorty.
Alright, that’s the story. Get on it if you can on the 23rd, it’s the one to chase.

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.
