The Lowdown
Alright, this is Rusty, and I’m looking at what we’ve got for the next 16 days. Honestly, it’s a tough stretch.
The overall pattern is grim. The wind is relentless out of the east and east-northeast, and for Shek O (Hong Kong), that means cross-on or onshore conditions almost the entire run. The water temp is sitting at about 83°F right now, which is average for the time of year, with no real anomaly to get excited about.
We start off with nothing. The first half of the period is a write-off. From Wednesday the 16th right through to about the 25th, the swell is tiny, the wind is wrong, and every surf window is classed as poor. The wave energy stays weak, often in the double digits – like on the 21st it’s down to 17 (weak energy). There’s a solid 9-day gap here with nothing worth paddling out for.
The best of what’s on offer – and I use that term loosely – shows up near the end of the month. On the 29th of September, we get a slight change. The wind swings to the west-southwest in the morning and afternoon, turning cross-offshore, and the conditions go clean. But the swell is barely there at 0.3 ft from the east, with periods around 10 seconds. The energy is almost nothing – 5 in the morning and 4 in the afternoon (weak energy). So while it’ll look pretty and clean, you won’t be catching much. This is really only a standout if you are desperate for a glassy paddle and no waves.
Into the 1st of October, we see a bump. Swell comes up a bit to 3 ft from the east, but it’s short-period stuff at 5-6 seconds, and the wind cranks back onshore from the east-northeast at 16-19 mph. The wave energy gets to 62 (still weak to low-moderate), but with that lumpy cross-on wind, it’s going to be messy. No standouts here for quality surfing.
Basically, this is a blank run for the area. If you’re a kite surfer, the stronger east winds on the 30th of September (25 mph) and the choppy conditions might offer something, but for traditional paddle surfing? Leave the board at home. Forecasts can change, but right now there’s no real reason to get hopeful.
Rusty.

Information about the Shek O Surf forecast
The above surf forecast table for Shek O provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shek O can be found by selecting the local surf guide option on the grey menu. Our Shek O 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 (Shek O) 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 Shek O 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.
