The Lowdown
Alright, let’s talk about H-Reef in feet and miles per hour.
Water temp is about 79°F – right on the money for this time of year. The first chunk of the forecast is a bummer. From today through the end of the month, we’ve got a long stretch of straight-up poor surf. The wind is a moderate side-shore breeze, 15 to 16 mph, and the swell is short-period, mostly 6 to 8 seconds. The combined energy is weak to moderate (283 to 493). It’s a cross-chop mess.
On the 26th of July, Sunday, the swell period jumps to 14 seconds – that’s groundswell. The energy gets strong (850 to 1569). But the swell is only 4 ft to 4 ft, and the wind is still a side-shore 16 mph. It’s rated marginal. Not a total loss, but not clean.
The one true standout is the morning of the 29th of July, Wednesday. The swell is 8 ft from the ENE, with a 10-second period, and the energy is strong (1276). The wind is a cross-offshore breeze at 12 mph from the ESE, and it’s described as “clean”. That’s a beautiful thing for a reef break like H-Reef (exposed to NNE). This is for experts only – 8 ft is too big for beginners. That morning window is the session to circle on the calendar.
After that, there’s a small gap, and then a maybe on the 5th of August, Wednesday morning. Swell is 7 ft from the ENE, period 11 seconds, energy strong (1114). The wind is a light cross-onshore, which isn’t ideal, but it’s light enough it might work. It’s a long-range look, so take it with a grain of salt, but it’s a potential for the experienced crew.
The rest of the 16 days is a washout – poor conditions and marginal surf. The first week is a blank, and the second week has a couple of maybe-days. It’s a rough run, but it won’t stay this way forever.

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.
