The Lowdown
Alright, Rusty here again. Let's talk in feet and miles per hour, because the story is the same – just a different ruler.
The next sixteen days are a real bummer. There's a long, dry gap with no decent surf to speak of right from the start.
From Monday, July 20th through the end of the month, the wind is all cross-shore or cross-onshore, never clean. The swell is small, with wave heights around 3 to 4 feet, and the period is short, mostly 7 to 8 seconds – just weak, gutless waves. The combined energy is in the low hundreds, barely a whisper. Water temp is 79°F, which is normal for the time of year, but that's the only thing that's normal.
There's a tease on Wednesday, July 22nd, with a 5-foot swell and a 12-second period, but the wind is still messing it up. The same story repeats: a bump in energy on the 25th, but it's cross-shore and choppy. The real frustration comes on Sunday, July 26th. The energy hits 1950, with a 6-foot swell and a 16-second period – that's a proper groundswell. But the wind is cross-onshore, and the surface is ruined. The morning is just "marginal", the afternoon is a total write-off.
The waves get bigger, up to 7 feet, but the wind never drops out of the cross or cross-onshore quadrant. A few days later, on the 29th, the wind turns offshore, but the swell is already dropping. It's a string of almosts and could-have-beens.
H-Reef is a reef break, a consistent spot for advanced surfers, but it's being hammered by bad wind. The energy numbers are high, but the quality is zero. Honestly, with the persistent cross-shore wind and the building swell, this stretch looks more interesting for kite surfing than for paddle surfing. A real shame.
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.
