Alright, this is Rusty coming to you live from Right and Left Side. We’ve got a bit of a mixed bag on our hands, so let’s break it down.

First up, the water temp is sitting at a warm 85°, which is pretty much spot on for this time of year. Nothing wild there.

We kick things off on Thursday morning, July 9th. It’s glassy, dead calm, with a solid 6 ft swell rolling in from the WNW at a nice 13-second period. The combined energy is pumping at (1269), so there’s a lot of power behind it. The reef is breaking clean, and for experienced surfers, this is the standout session of the whole run. The wind is zero, the waves are groomed, and it’s just you and the ocean. The only downside? This spot is inconsistent, so when it turns on, you’ve gotta be on it. Crowds are possible.

Thursday afternoon sees a light cross breeze come up, and the quality drops a notch. Still the same 6 ft swell, but the surface gets a little bumpy. It’s surfable, but morning was the time.

Friday morning, July 10th, the swell bumps up to 8 ft from the W, with a period of 14 seconds. The energy is strong (2442). But the wind is cross-shore at 15 km/h, and it’s putting a cross-chop on the face. That’s a lot of power with a messy surface – this one is for the experienced crew only. The swell is getting big, and the cross wind makes it a handful. The afternoon is similar, with a bit more wind.

Saturday, July 11th, the swell drops a little to 7 ft, period still 14 seconds, but the cross-shore wind picks up to 25 km/h. It’s choppy, and the quality is marginal. This is not the day to paddle out unless you’re looking for a battle.

By Sunday morning, July 12th, we’ve got a risk of thunderstorms, but the wind switches to a cross-offshore from the E at 20 km/h. The swell is 6 ft, period 14 seconds, and the energy is still strong (1441). The surface cleans up nicely, and this is a good second option for the weekend. The afternoon is smaller at 4 ft, but still clean.

Monday, July 13th, is a real bright spot. Early morning, the wind goes offshore from the SE at 20 km/h, and the swell is a clean 4 ft from the WNW at 14 seconds. The energy is moderate (615), but the offshore wind is grooming it perfectly. It’s a gentle, clean, and very surfable morning. The afternoon holds similar with a lighter 15 km/h offshore. This is a solid session for a weekday.

Then things go quiet. From Tuesday, July 14th, through to the end of the third week of July, we get a long stretch of small, weak, and windy conditions. The swell drops to 1 ft – 3 ft, the wind is strong and cross or cross-off, and the energy numbers drop into the double digits. There’s a lot of days with risk of thunderstorms and strong breezes. It’s pretty much a write-off for paddle surfing. The setup with the strong cross winds and low swell might actually be more interesting for kite surfing than a traditional surf.

We do see a pulse returning on the 22nd of July, Wednesday morning, with a 6 ft swell from the W at 10 seconds. The energy is moderate (608), and the wind is cross-offshore from the ENE. It’s clean, but the period is short, so the waves won’t have that long-period grunt. The afternoon is a bit smaller at 5 ft, but still clean. It’s a promising signal for the end of the month, but it’s a long way out, so keep an eye on it.

The standout is Thursday morning, July 9th. Glassy, 6 ft WNW swell, 13-second period, and the reef is working perfectly. That’s the one you don’t miss.

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.

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.
