The Lowdown
Alright crew, Rusty here. Let’s be real with you. This 16-day stretch is a tough one for H-Reef. There’s no perfect day, but there’s a small window that might just be worth the drive.
Water temps are about 80°, which is pretty normal for the season, so no surprises there.
From Wednesday the 12th through Friday the 14th, it’s a write-off. A steady cross-shore wind from the ENE is making a mess of things. The swell is small, around 5ft to 7ft, with a short period (7-9 seconds) and weak energy (225 to 681). The surface is choppy and ugly. Not worth your time.
Saturday the 15th brings a big spike in swell, but it’s a stormy mess. We’re looking at 12ft to 13ft from the E/ENE, with a massive energy jump (3120 to 4589). The wind is a strong breeze from the ENE, still cross-shore, and rain showers are likely. This is expert-only territory, and even then, the conditions are poor. This setup looks more interesting for kite surfing than paddle surfing.
Sunday the 16th is where we get a glimmer of hope. The wind shifts to a lighter ESE cross-off, and the swell drops to a still solid 10ft to 12ft. The wave report says “clean,” which is a huge improvement. The period is still short (8-9 seconds), but that cross-off wind will smooth out the surface. This is the best window. It’s a big swell, so it’s for experienced surfers only, and with energy levels around 1117 to 2232, it’s got some power. The only downside is the risk of thunderstorms.
From Monday the 17th onward, it’s back to the same old story. The swell drops back to 4ft to 6ft, and the wind swings back to a cross-shore ENE or E, with moderate breezes keeping the surface choppy and poor. The energy is low (162 to 493), and the period is short (6-9 seconds). There’s a small bump in energy around the 25th and 27th, but the wind is still cross-shore and conditions are still poor. It’s a long, flat run after that Sunday.
So, bottom line: the only real chance is Sunday the 16th. H-Reef is a reef setup, so it can handle the size, and with that cross-off wind, it’ll be the cleanest it gets. It’s a big, powerful swell (10ft to 12ft from the E), so bring your big wave board and your wits. It’s not perfect, but it’s the best on offer.

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.
