The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a tricky 16-day window ahead, with only one real standout that’s worth paddling out for. The rest of the run is a bit of a write-off, so we’ll keep it tight.

The only break that’s offering anything decent is H-Reef. It’s an advanced reef setup, and it’s *fairly consistent*. The first few days are a mess. Saturday the 5th through Monday the 7th are dropping a dishwater 7ft to 8ft swell from the ENE, but the wind is a cross-shore mess with a cross-chop. The swell energy is pumping—1663 to 1847 (moderate to strong wave energy)—but the quality is just not there. It’s a textbook case of lots of energy but no shape. Forget it.

Now, Tuesday the 8th is the one. Morning session at H-Reef is looking clean. The swell drops to 6ft from the ENE, period is 11 seconds, and the wind goes light and cross-offshore. That’s the magic combo. The combined energy is 1089 (moderate wave energy), and the conditions are described as excellent for experienced surfers. This is the standout. The swell direction is ENE, and the optimum swell for this reef is from the NNE, so it’s a touch off, but with that clean wind and solid groundswell, it’s going to be fun. The water temp anomaly is about average for this time of year, so nothing weird to report. Be aware, crowds are *sometimes* around here, so you might have a few others in the lineup.

After that morning session on Tuesday, it goes downhill fast. Tuesday afternoon the swell drops to 6ft and the wind goes back to a cross chop, scoring a 1. Then from Wednesday the 9th all the way through to Sunday the 20th, it’s a long stretch of poor surf. The swell hangs around 3ft to 7ft, but the period drops to 7 or 8 seconds, the wind is either cross or cross-onshore, and the combined energy falls to 300–500 (weak wave energy). The comments say “poor surf conditions” over and over. There’s a 12-day gap of nothing worth riding here. If you’re a kite surfer, some of that cross-shore wind with a bit of swell might look interesting, but for paddle surfing, it’s a no-go.

So, bottom line: if you’re an experienced surfer, get on H-Reef on the morning of Tuesday the 8th. That’s your window. Otherwise, put the board away for a while.

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.
