The Lowdown
Alright, let’s get into it. I’m looking at the forecast for Jacks Point over the next couple of weeks, and I’ll be straight with you—it’s a pretty quiet run. There’s nothing massive on the horizon, but there are a few windows where the conditions line up enough to get a fun session in.
The water temperature is sitting around 49° right now, which is about 0.9° warmer than the long-term average for this time of year. So it’s a touch on the mild side, but nothing too wild.
The first real standout is shaping up for Wednesday morning, August 19th. We’ve got a clean, offshore breeze from the WNW at 6 mph, with swell coming in from the SE at 4 ft and a long period of 15 seconds. That’s proper groundswell energy, and combined wave energy is moderate (556). Jacks Point is a reef setup, so that long period should wrap in nicely. The wind is offshore, which means glassy faces and good shape. This is the best session on offer—if you can only get out once, make it this one.
Tuesday afternoon, August 18th, has a bit more size—6 ft from the SSE with a 10-second period—but the wind is a fresh cross-off at 19 mph, so it’s going to be a bit lumpy. Combined energy is strong (597), but the conditions are only marginal. That one’s more for the experienced crew if you’re after a bit of push.
The rest of the first week is mostly small, clean, and ordinary. Saturday morning, August 15th, has 2 ft from the east with a 7-second period and a cross-off wind, but it’s weak (60) and the period is short, so not much to write home about. Sunday morning, August 16th, has a long 16-second period on 1 ft, but the swell is tiny and the energy is moderate (122). Clean, but you’ll be scratching for every wave.
After the 19th, the surf drops right off. From the 22nd of August through to the end of the month, we’re looking at tiny swell—most days under 1 ft—with periods all over the place. The wind is often light or cross-onshore, and the combined energy is weak (mostly under 100). There are a few glassy mornings, like the 22nd and 27th, but the swell is just too small to do anything with. That’s a solid week or more of flat to near-flat conditions.
Bottom line: the standout is Wednesday morning, August 19th. Get on it while it’s clean. The rest is a waiting game.

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