The Lowdown
G’day, Rusty here, with a look at the waves ahead for H-Reef. The water temp is sitting at 79°F – that’s pretty much average for this time of year, so no wetsuit worries.
Alright, let’s be straight up: the first week and a half is a tough slog. From Tuesday the 21st right through to Friday the 24th, it’s all cross-shore wind and messy, poor surf. We’re talking waist-high windswell, short period around 7 seconds, and the energy is weak to moderate (229 to 430). Not worth paddling out for.
Saturday the 25th stays average – a bit more size, around 6ft, but still cross-shore and the energy kicks up a notch (570), but the rating’s still marginal. The wind is still a problem. Sunday the 26th is when things get interesting. The swell jumps to 5-6ft from the east, but the period hits 16 seconds – that’s proper groundswell. The energy is strong (1551 to 1829). The wind is still cross-shore though, so while there’s power, it’s not clean. A big groundswell with that kind of period can make H-Reef a bit too straight, especially with the wind on it.
Monday the 27th and Tuesday the 28th keep that energy up (1369 to 1598), swell around 6ft, period easing from 14 to 13 seconds. Wind is gentle cross-shore or cross-onshore, so there’s a slight chop. It’s still marginal.
The standout window starts to shape up from Wednesday the 29th of July through to Thursday the 30th. Swell holds at 6ft to 7ft from the east-northeast, period around 10-12 seconds. The energy is still strong (604 to 1425). The wind gets lighter, especially on the 30th morning with a slight air and light cross-onshore breeze. That’s your best bet for a session – the swell is solid, the period is good, and the wind is almost glassy. The cross-onshore is light, so it’ll be lined up. This is the pick of the outlook.
After that, Friday the 31st and Saturday the 1st of August drop right off – tiny 2ft to 3ft, long period but no power (276 to 491). Sunday the 2nd has a bit of a spike to 6ft but with short 8-second period and cross-shore wind – messy again.
Then Monday the 3rd to Wednesday the 5th of August brings back some decent groundswell, 4ft to 7ft, period 12 to 16 seconds, energy moderate to strong (1089 to 1282). Wind is lighter, mostly gentle cross-shore, so the waves will have shape but the wind will still put a bit of texture on it. Not a standout, but worth a look if you’re keen.
So, if you’re picking your moment, Thursday the 30th of July morning is the one to circle. Solid east-northeast swell around 6ft, a decent 10-second period, and the lightest wind of the whole run. That’s the cleanest H-Reef will get.
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.
