The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way.

We’ve got a messy start this week, but don’t write it off just yet. The first real chance to get wet isn’t until Friday morning, the 31st of July. Before that, the swell is too big and the wind is a disaster. Tuesday the 28th has a massive 12 ft to 15 ft WSW swell with a near gale cross-shore, so that’s a hard pass. Wednesday morning the 29th sees a 16 ft SW swell and strong cross-onshore wind – way too big for this break and choppy as hell. Thursday the 30th is smaller at around 8 ft, but the wind is still cross-shore and the conditions are marginal.

The first real standout is Friday morning, July 31st at Rivoli Bay. The swell drops to a clean 6 ft from the SW, with a period of 12 seconds and gentle cross-offshore wind. The water is sitting at 57°, which is about average for the time of year – nothing unusual there. The combined wave energy is moderate at 1197. It’s a clean, manageable size for intermediates, and the offshore wind will put a nice face on the waves. This is the one to aim for if you can get out of work.

Then Friday afternoon gets even better – the swell settles to 5 ft from the SW, period bumps to 13 seconds, and the wind drops to a light 6 mph cross-offshore. The energy is still moderate at 1449, and conditions are described as clean. This is a solid window for experienced surfers to have a ball.

Saturday, August 1st brings a fresh offshore wind with a 7 ft SW groundswell (17-second period) in the morning. The energy is up to 3248, so there’s definitely some push. The wind is moderate offshore, so it’ll be clean. The afternoon gets a bigger 10 ft SW swell (18 seconds) with a fresh offshore breeze – that’s edging into expert territory, but if you’ve got the skill, it’ll be a ripper.

Monday, August 3rd is another highlight. The morning has a 12 ft SW swell (14 seconds) with a light offshore breeze, which is too big for beginners, but strong intermediate and expert surfers will find plenty of power. The afternoon glass off with a 10 ft SW swell and light cross-offshore wind is a real treat.

Tuesday, August 4th is a dream day – the morning offers 7 ft SW swell with a gentle cross-offshore breeze, and the afternoon goes completely glassy with the same swell size. The energy is moderate at 3174, and the wave quality is excellent. That afternoon glass-off is about as good as it gets.

Wednesday, August 5th afternoon has a 10 ft SW groundswell (17 seconds) with a light offshore wind – clean and powerful. Thursday, August 6th is a bit smaller at 5 ft to 6 ft, but with moderate offshore winds, it’s a great option for a fun session without the crowd.

Friday, August 7th is a weird one – a 4 ft SW swell with a very long 22-second period. That’s super long-period groundswell, and at a beach break, it might break a bit straight. Still, it’s clean and offshore, so worth a look.

Saturday, August 8th morning has a 7 ft SW swell with an 18-second period and moderate offshore wind – solid and clean.

After that, Sunday the 9th and Monday the 10th are a write-off again with strong onshore winds and big, messy swell. The next good window comes back on Tuesday, August 11th morning – a 6 ft SW swell with a light cross-offshore breeze and clean conditions. That’s a nice way to end the run.

The absolute best on offer is Tuesday afternoon, August 4th – glassy conditions, 7 ft SW swell, and excellent quality. That’s the session to circle on the calendar.

Rusty.

Information about the Rivoli Bay Surf forecast

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