The Lowdown
Alright, Rusty here again, same story, just in feet and miles for you. Shek O has been a drought for surf, and it’s gonna stay that way for a good week and a half. Water temp’s about 85°F, right where it should be for July.
Starting Tuesday, July 28th, easterlies are blowin’ 12 mph in the morning, cranking to 22 mph in the arvo. Swell’s a tiny 3 ft to 5 ft, period a weak 6 seconds. Combined energy is low at 61 to 115. Onshore trash. Don’t bother.
Wednesday the 29th: same easterly wind at 19–22 mph, swell hits 6 ft but still 6-second period. Energy climbs to 230, but it’s lumpy and blown. No good.
Thursday the 30th drops to 2 ft to 3 ft, period 5 seconds, wind shifts but stays messy. Friday the 31st and Saturday August 1st: onshore easterlies over 12 mph, weak swell—nothing.
Sunday August 2nd morning goes glassy—wind zero—and there’s a 4 ft SSE swell, period 5 seconds. Energy only 81. “Surfable but ordinary.” If you’re desperate, that glassy hour might give you a few rides.
Monday the 3rd through Saturday the 8th is almost flat. Swell barely hits 1 ft, some long-period lines at 17 seconds on the 3rd arvo but only 0.3 ft—a ripple. Glassy mornings but no wave to ride.
Sunday August 9th late arvo: 5 ft east swell, 6-second period, light cross-off wind, energy 160. “Surfable but ordinary.” Still short period—fat and meh.
Monday the 10th and Tuesday the 11th: easterly breezes, small cross-onshore chop, 2 ft to 3 ft. Weak.
The only real standout is Wednesday August 12th. Morning goes glassy, and we get a proper pulse: 7 ft east swell, 8-second period. Energy hits 939—solid power. “Expect very good surf conditions.” That’s your window. Remember it’s two weeks out, so promising but not locked. Afternoon on the 12th gets a light cross-shore breeze at 9 mph, swell bumps to 8 ft, period 9 seconds, energy 1041—still surfable, but the morning is the best. At 8 ft, it’s expert territory.
If I had to call it: Wednesday morning, August 12th, at Shek O—east swell around 7 ft, glassy, good quality. That’s the one.
Rusty out.

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.
