The Lowdown
Righto mate, Rusty here. Let's have a look at what's on the table.
Honestly, it’s a bit of a grim run for the most part. We’ve got a solid 16-day window, but there’s a massive dry spell at the start. From now through to the morning of Saturday the 15th of August, there’s barely a whisper of anything rideable – just a lot of cross-shore wind, choppy faces, and average waves at H-Reef. That’s close to a full week of nothing you’d want to paddle out for.
The first real sign of life shows up on Sunday the 16th of August, but it’s not until Monday the 17th of August that we get a proper standout. Monday morning at H-Reef is the pick of the entire outlook. The wind goes glassy – dead calm, zero wind – and the swell cleans up nicely. You’ve got a 7ft east-northeast groundswell rolling in with a solid 10-second period. That longer period means better shaped waves, more energy behind 'em, and longer lulls between sets, making the paddle out a bit easier. The combined wave energy hits 801 (moderate to strong), so there’s some real push. It’s a reef break exposed to swell, and the optimum direction from the north-northeast is bang on. Swell direction is northeast, so it’s working well. This is for advanced surfers, and it’s fairly consistent. You might have to share the lineup though – crowds are possible here.
After that, things drop off pretty quick. By Tuesday the 18th of August, the swell fades right back down to under 3ft and the cross-shore wind returns. The rest of the fortnight looks pretty bleak – persistent cross-shore winds in the 12 to 19 mph range, short-period windswell, and poor surf conditions with weak wave energy (mostly under 300 in the combined energy reading). It’s a long stretch of nothing special.
So here’s the bottom line: don't get excited for the next week. If you’re an experienced surfer and you can wait, Monday the 17th of August is your day at H-Reef. Get in before the morning glass-off disappears. After that, it’s back to watching the forecast and hoping something changes.

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.
