The Lowdown
Alright crew, Rusty here, switching to feet and Fahrenheit for you.
It’s a slow start for H-Reef. From Monday the 10th through Thursday the 13th, the wind is blowing cross-shore at 12 mph, and the swell is tiny and weak. The water temp is about average for the season. The combined wave energy is low (around 128 to 335), and the surf is just poor. Not worth paddling out.
Friday the 14th morning shows a bit more life, with swell hitting 7 ft from the east, but conditions are still marginal with a cross-shore breeze. The energy picks up to moderate (637), but the quality isn’t there. Friday afternoon falls apart again.
Saturday the 15th brings a big increase to 12 ft from the east, but the wind is onshore and choppy at 12 mph, with rain showers. The energy is very strong (4653), but it’s messy. This looks better for a kite than a surfboard.
The standout is Sunday the 16th. The morning has a massive 18 ft swell from the east-northeast, but the wind is howling cross-onshore at 18 mph with a risk of thunderstorms. The energy is extreme (18112). But the afternoon is the real deal — the wind shifts to the southwest at 12 mph, turning cross-offshore, and the swell holds at 20 ft. The conditions clean up, and the energy is still insane (11658). This is an expert-only session at the reef. If you’ve got the stones, Sunday afternoon is your best bet.
Monday the 17th morning is another gem. The wind goes dead calm, glassy, and the swell is a solid 10 ft from the ENE. The energy is strong (1421), and conditions are excellent for experienced surfers. That glassy morning will be perfect. The afternoon stays clean with a light cross-offshore breeze and 8 ft waves.
From Tuesday the 18th through Tuesday the 25th, it’s back to small and weak. Swell drops to 3 ft to 6 ft, the wind is cross-shore, and the energy is low to moderate. There’s a marginal uptick on the 25th morning with 6 ft and a bit more energy (526), but it’s nothing special.
So, the first week is a wash. Your best chances are Sunday the 16th afternoon and Monday the 17th morning. That’s the juice.
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.
