Table - best surf conditions forecast for Right and Left Side over the next 16 days.
Alright folks, Rusty here. Let’s get into it.
Right off the bat, we’ve got a bit of a tricky window. The surf at Right and Left Side is a classic reef setup, and it’s not the most consistent place. It’s also too small for a lot of the next week, so we’re looking at a bit of a wait before things get interesting.
The good news starts on Saturday afternoon, the 11th. We’ve got a solid 7ft swell from the WNW, but the wind is a messy cross-shore from the NE at 16 mph. The water is sitting at 84°, which is pretty much average for this time of year. The energy is pumping with a reading of 1574, but that wind will chop it up. It’s a bit of a looker, not a standout.
Sunday the 12th is where it gets cleaner. The morning shows a 5ft WNW swell (972 energy) with a cross-offshore breeze from the east at 12 mph. That’s a proper clean window. Then the afternoon turns even better: 5ft from the west, 13-second period, and a clean offshore wind from the ESE at 12 mph. The energy is 994, and the comment says “expect very good surf conditions.” This is the best on offer for the first week. The reef will handle that long period groundswell nicely.
After that, Monday the 13th drops off a bit. 4ft in the morning with a light S wind, clean but smaller. The afternoon is only 3ft. Tuesday the 14th is glassy but tiny, 3ft and 2ft. The energy plummets to around 170. It’s surfable, but you’ll be on a longboard, and it’s not worth planning a session around.
From Wednesday the 15th through to the 23rd, it’s a massive gap. The swell is either flat, tiny, or the wind is howling cross-shore. There’s a stormy pattern with risk of thunderstorms and poor conditions. The energy drops into single digits and low double digits. It’s a real blank run. The only blip is on the 21st afternoon when a 6ft W swell appears (550 energy), but the wind is a fresh cross-shore at 19 mph, which makes it messy and poor for a reef. Not worth it.
Now, hold on. The end of the window shows a glimmer. Thursday the 24th morning: a 5ft W swell (414 energy) with a light cross-offshore breeze from the south at 6 mph. That’s clean again. The period is 10 seconds, so it’s a decent groundswell. This is your second standout, but it’s a week and a half away, so take it with a grain of salt. The afternoon gets a bit more cross-shore and drops to 5ft. The 25th and 26th are small and windy again.
So, the real highlight is Sunday the 12th afternoon. That offshore wind and the 5ft west swell on the reef will be clean and fun. The energy is solid, and the direction suits the break. The other worthwhile session is the morning of the 24th, but that’s a long way off. For the rest, it’s a waiting game.
Rusty out.

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