The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Right off the bat, I gotta be straight with you: the next two weeks are looking pretty average for H-Reef. This is a reef break that’s fairly consistent and exposed, with an optimum swell from the NNE. The problem is, we’ve got a persistent cross-shore wind from the ENE and E that’s messing up the surface, and the energy is just not lining up right. The water temp is about average for this time of year, so no surprises there.
We start off on Friday morning, August 7th, with swell at 2ft from the NE, period of 7 seconds – that’s short-period wind swell, weak energy (86). The wind is cross, 12 mph, and it’s choppy. Not worth paddling out. Friday afternoon and Saturday bump up a bit, swell hits 4ft to 5ft from the ENE and E, but the period stays short at 7 seconds, and the energy climbs to 146 and 224. Still, the cross-shore wind keeps it messy.
Sunday, August 9th, sees a bit more size: 6ft from the E, 8-second period, energy jumps to 391. That’s moderate energy now, but the wind is still cross at 16 mph, so the surface is lumpy. The score is zero for a reason. This pattern continues right through the week and into the next. Monday and Tuesday, swell holds around 5ft to 6ft, energy between 252 and 429, but it’s all cross-shore chop. No clean conditions.
The second week isn’t looking any better. By Saturday, August 15th, swell builds to 7ft from the ENE, 8-second period, energy hits 588. But the wind is 16 to 19 mph cross-shore, and the forecast says “poor surf conditions.” A 7ft swell with that much onshore wind is more of a washing machine than a wave. For advanced guys only, and even then, it’s a struggle.
There’s a tiny glimmer on Monday, August 17th, when the morning session gets a “marginal” rating (score of 1) – swell 7ft from the ENE, 8-second period, energy 742. The wind drops to 12 mph cross-shore. Still not clean, but if you’re desperate, it’s the closest thing to a wave all week. By Tuesday, August 18th, it’s back to poor.
The last few days, from August 19th to 22nd, the swell drops to 4ft to 6ft, period stays short, and the wind lightens a bit but turns cross-on from the NE and ENE. The energy is moderate (296 to 451), but the wind direction is onshore – it’s going to be choppy and weak.
Honestly, there’s no standout session in this whole 16-day window. The best of a bad bunch is probably Monday, August 17th, early, when the swell is 7ft with moderate energy (742) and the wind is just cross, not full onshore. But don’t expect clean faces – it’s going to be lumpy, and that reef can be unforgiving when it’s messy. If you’re an advanced surfer with a shortboard and low expectations, you might snag a few. For everyone else, leave the board at home.
This is Rusty, signing off.

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.
