The Lowdown
Alright, I’ve looked over the charts for your area, and I’m not gonna sugarcoat it – this is a pretty grim stretch for Surfside Jetty. The next couple of weeks are looking like a tough slog, with very little to get excited about. Most days are served up with weak, messy swell and the wind just doesn’t seem to want to play nice.
Let’s start with the pattern. The forecast period is basically a long, dry spell of small, poor-quality surf. The combined wave energy is weak, dipping into the double digits like 83 on the 22nd and only occasionally reaching a modest 343 on the 16th. The swell is tiny, mostly around 1 ft to 3 ft, and it’s coming from the SSW or SW, which is not the best direction for this spot. The period is long, between 13 and 19 seconds, but with such little height, that long period just means long waits between limp waves.
The water temperature is about average for this time of year, so no complaints there.
The first real standout, if you can call it that, is the morning of Monday the 24th. The wind goes glassy, with a light breeze from the west at 5 km/h. That’s the only window of clean conditions we see. The swell is a tiny 1 ft from the SW, with a period of 18 seconds. The combined energy is 231, which is still weak. It’s surfable, but you’ll be working hard for little reward. The rest of that day, and the days around it, are plagued by cross-onshore winds and choppy, crummy waves.
After that, the pattern doesn’t really improve. Late in the month, around the 29th and 30th, we see the swell bump up a touch to 3 ft, still from the SSW, but the wind is either onshore or cross-onshore, keeping the quality poor. The combined energy climbs to 360 on the morning of the 29th, but it’s all wasted by the wind.
Honestly, the whole period is a write-off for decent waves. The sets are inconsistent, the power is low, and the conditions are just not cooperating. If you’ve got a kite, this might be more interesting than a surfboard, because the wind is blowing consistently, but for paddle surfing, it’s a real bummer. The forecasts can always change, but right now, I’d give this one a miss.

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