The Lowdown
Alright folks, Rusty here. Let's talk about what's happening at H-Reef.
Look, the next couple of weeks are a bit of a mixed bag for us. We've got some serious pulse of energy coming through, but the wind is going to be a pain in the neck for a while. You're gonna have to be patient and pick your windows carefully, because there are definitely some clean sessions on the horizon.
The week kicks off on a rough note. Tuesday the 1st through to Thursday the 3rd, we're looking at a solid but messy swell, around 6ft to 8ft from the ENE, but it's being hammered by a fresh 15-19 mph cross-shore breeze. The combined wave energy is moderate to strong (449-747), but with that wind, the surface is a lumpy, choppy mess. It's a total write-off for a proper surf. We move into the weekend, and things get more interesting but stay marginal. The swell really kicks in from Friday the 4th through Sunday the 6th, with a long-period groundswell from the ENE (14 seconds!) pushing waves up to 8ft. The combined energy is huge, hitting four digits (999 up to 2212), so there's power in the water. But the wind is still a cross-shore or cross-onshore breeze, keeping things choppy. That long period is great for a reef like H-Reef, but the winds are just ruining the party.
Then we hit a bit of a lull around Tuesday the 8th, with the swell dropping right off to 3ft. Not much to get excited about there.
Now, here’s where I get a bit excited. The real standout is looking like Sunday the 13th of September. We've got a clean 8ft to 8ft groundswell rolling in from the ENE (period of 10-11 seconds), so the combined energy is still strong (1159-1218). But the wind... oh boy. The morning has a light 3 mph cross-onshore, but the afternoon on Sunday the 13th is going to be glassy. That’s right, a flat calm surface. For a reef break like H-Reef that is exposed to the NNE, this is your best chance at some flawless, groomed lines. The swell is a touch bigger (8ft) for the experts on Monday the 14th, but the wind is back to a light cross-shore. Sunday the 13th afternoon is the one to circle on the calendar.
After that, the swell fades again into a poor state for the 15th and 16th.
So to wrap it up: don't bother this week. The wind is the enemy. The best bet in the whole 16-day window is the afternoon of Sunday the 13th. Mark it. Go get some glassy, long-period waves at H-Reef. The setup is right.
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.
