G'day, I'm Rusty. Let's have a look at what's on the card for Right and Left Side.

Right, so the next week to ten days is the only time worth talking about, then it all goes quiet for a stretch. The highlight window is from Thursday the 9th of July right through to Monday the 13th. After that, the surf drops away into nearly nothing for days.

Let’s talk about the standout. Thursday the 9th of July morning at Right and Left Side is the pick of the bunch. We’ve got a solid 6ft swell pouring in from the WNW with a long 13-second period, and the wind is a glassy light NE breeze at just 3 mph, staying nice and cross-off. The water temperature is sitting at 85°, which is about average for this time of year. The combined wave energy is a solid moderate at 1249 (moderate wave energy). This is clean, lined-up reef surf for the experienced crew, and it’s the best you’ll see.

Thursday afternoon holds up with 6ft WNW swell and silky light N winds, but it's a touch cross-on, so not as perfect as the morning session. Still a good call.

Friday the 10th of July morning brings a bigger pulse at 8ft from the west with that long 14-second period, but the NE wind is up to 9 mph and cross-shore. It’s got a lot of energy with 2601 (moderate wave energy) directed here, but the wind will put a bit of chop on it. This is solid, powerful stuff only for the experienced – over 8ft is expert territory. The afternoon is similar but with a bit less size.

Saturday the 11th and Sunday the 12th are a mixed bag. Saturday is blown out with onshore wind and choppy conditions. Sunday the 12th bounces back nicely: the afternoon session has 6ft WNW swell, a light 9 mph SSW cross-off breeze, and clean conditions. The energy is 1511 (moderate wave energy). That’s another excellent window for the crew who know the reef.

Monday the 13th of July still offers clean 5ft WNW swell with cross-off winds, but the energy drops to 923 (moderate wave energy). It’s good, but not as punchy as the previous days.

Now, the bad news: from Tuesday the 14th of July, the swell just tanks. We’re looking at tiny 2ft to 1ft windswell with poor onshore or cross-shore breezes for days. There's a flat spell from the 14th through to the 17th of July where the score is zero. Don’t even bother.

Things try to pick up again on Saturday the 18th of July with some clean 3ft NNE groundswell, 12-second period, and light cross-off winds. The energy is around 499 (weak wave energy). It’s small but clean – a Sunday cruiser for the loggers. That carries into Sunday the 19th of July morning, but by the afternoon a strong 25 mph SW wind messes it up.

Then Monday the 20th of July afternoon throws a surprise: a sudden 8ft W swell with 10-second period and 1165 (moderate wave energy) but the wind is a screaming 22 mph cross-off – that’s a kite-surfing setup if ever I saw one. Not for paddling.

After that, the forecast fades back into small, messy, onshore junk right through to the 23rd of July. The consistent run is short and focused: get out on Thursday the 9th through Monday the 13th of July, especially the Thursday morning glass-off. After that, it’s a long wait.

Stay safe, Rusty.

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.
