The Lowdown
Alright, Rusty here. Let’s take a look at what we’ve got for H-Reef over the next sixteen days.
Tell you what, it’s a rough start. The whole first week and a half is just a write-off. We’re looking at a solid ten days of poor surf conditions straight up. The wind is coming in from the E and ENE mostly, 15 to 25 km/h, and it’s cross or cross-on, which is keeping everything chopped up. The waves are there, but the quality is just not happening. From Thursday the 10th right through to Sunday the 20th, the combined swell energy is mostly moderate (432 down to 304), but that’s useless with the wind state. Not one session scores better than a zero. It’s a bad run.
Then, towards the end of the run, we finally see a bit of life. Monday the 21st rolls around and things start to shift. The wind stays cross from the E at 20 km/h, but the swell ticks up a bit. The morning has 6ft from the ENE with a period of 10 seconds, and the combined energy jumps to 525 (moderate wave energy). Still labelled as marginal, but that’s the first sign of hope. The afternoon is a little better: 6ft from the ENE, same 10-second period, energy up to 687. That’s a proper moderate energy. It’s still cross-shore, but there’s a slight cross-chop, not total slop.
Tuesday the 22nd is the standout of the whole outlook. Morning session brings 7ft from the E, a 10-second period, and a solid 897 combined energy. That’s strong wave energy. The wind is cross from the ENE at 20 km/h, so it’s still not glassy, but for H-Reef, that’s a definite improvement. This is for experts though – 7ft is too big for beginners. The swell direction from the east is matching the optimum swell direction from the NNE as best we’ll see. Afternoon is a touch smaller at 7ft, but the wind drops to 15 km/h from the ENE, also cross, so it’s a bit cleaner with a slight cross-chop. Energy is still high at 796 (moderate to strong).
Wednesday the 23rd holds onto some size. Morning has 6ft from the E, 10-second period, 677 energy. Wind is ENE at 15 km/h, cross-on, so it’s a little choppier. Afternoon is the same swell, but the wind turns cross, which cleans it up slightly. Still only marginal, but there’s a wave there.
After that, it fades. Thursday the 24th drops back to poor conditions, and the run into Friday the 25th is back to small and messy. So to be clear, the real window to focus on is Monday the 21st through to Wednesday the 23rd, with Tuesday the 22nd being your best chance for the biggest, most energetic surf of the period. It won’t be perfect, but it’s the best on offer.
Water temp on the morning of the 10th is 79°F with an anomaly of -0.9°F, which is about average for this time of year. So, no surprises in the water temp.
This is only a single break forecast, so no need to switch regions. H-Reef is a reef break, advanced level, fairly consistent, and the optimum swell is from the NNE. You’ll want to keep an eye on the tide if you paddle out, as the notes mention questionable tide conditions on those better days.
Stay patient. The first ten days are a write-off, but there’s a little pulse coming at the end.
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.
