The Lowdown
Alright, Rusty here. Let's break down what's in store.
Alright, folks, it's a bit of a mixed bag on the horizon. We're looking at a solid 16-day window, but the first week or so is going to be a real tease. The waves are there, but the wind is just not cooperating. We've got a persistent cross-shore breeze blowing from the east and east-northeast that's just chopping everything up. It's not going to be pretty. The water is sitting at a warm 80°F right now, which is pretty much spot on for this time of year, so at least you won't be freezing while you're getting frustrated.
Things kick off on Saturday, the 29th of August, with some chest-high waves around 5 ft, but that 12-16 mph cross-shore wind is going to make it a tough, bumpy session. The energy is weak, only about 375 (combined energy of all swells directed here). This same story basically repeats itself day after day through the first week. The swell bumps up a little, but the wind stays on it, making it a real grind. The best you can hope for is a "marginal" call, but nothing worth getting excited about.
Now, if you're a patient surfer, you might want to keep an eye on Thursday, the 3rd of September. The swell direction swings around to the ESE, and the period jumps to a nice 12 seconds, which is a proper groundswell. The energy also jumps up to 845, which is a decent bump. The problem is that the wind is still cross-onshore, which will put a bit of a chop on it. It's a tease, but it's the first sign of something better.
The real standout, and I mean the *only* standout in this whole run, is Thursday, the 10th of September. The wind finally drops to a gentle breeze at 9 mph from the ENE. It's still cross-shore, but it's much lighter, which should clean things up a lot. The swell is a solid 7 ft from the ENE, and the energy is moderate at 583. This is your best bet for a session that doesn't feel like a washing machine. It's not perfect, but it's the closest we're going to get.
Everyone else is pretty much a write-off for the first week. The forecast energy does get into the strong range on the 5th and 6th of September, with readings of 1918 and 2980, but the swell is big and messy, and the wind is howling at 22 mph. That's a recipe for a washing machine, not a surf session. It's more of a kite-surfing setup than a paddle-surfing one.
So, to sum it up: the first week is a battle against the wind. The second week has some promise, but it's a long way out. The clear winner is Thursday, the 10th of September. Mark it down and hope the forecast holds.
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.
