The Lowdown
Alright folks, Rusty here. Let's talk about what's happening at H-Reef over the next couple of weeks.
Straight up, the outlook for this reef break is a bit of a heartbreaker. For the first week and a half, we've got a real struggle on our hands. The wind is mostly a moderate cross-shore breeze, coming out of the east-northeast or east, and it's just not playing ball. Combined energy values for most of this period are moderate, sitting between 109 and 959, but the surf quality is repeatedly described as poor. The swell is mostly between 3ft and 5ft from the ENE, but the wind is just chopping it up, creating a cross-chop that's ruining the face. This spot needs that optimum NNE direction to really fire, and it's not getting it. We're looking at a long, frustrating stretch from Saturday the 12th right through to around Thursday the 24th of September where there's just nothing good to recommend.
Now, for those of you who can wait, there is a light at the end of the tunnel. The standout of the whole period looks to be the last few days, specifically the morning of Friday the 25th of September. The swell is still a moderate 5ft from the east with a 10-second period, but for the first time, we get a clean, cross-offshore breeze from the east-southeast at 9 mph. This is a huge deal. The combined energy is up at 512, and while it's not massive, the wind will give you those clean, workable faces that make H-Reef so special. The water temperature is sitting around 80°F, which is pretty normal for this time of year, so the slight anomaly isn't something to worry about.
The afternoon of the 25th will hold similar, though the energy drops a touch to 494. This is your window. It's far enough out that we can't lock it in, but the ingredients are there for a proper session. The rest of the forecast into the 27th fades back into marginal conditions with the cross-shore wind returning. So, if you've got patience, hold out for that final Friday.
Rusty.

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.
