The Lowdown
Alright, Rusty here. First off, let’s be straight with you – this outlook for Ricks Reef is a bit of a mixed bag. We’ve got a solid stretch of consistent swell, but the wind is gonna be a real headache for most of it. The water temp is sitting at about 85°F, which is pretty much spot on for this time of year, nothing unusual there.
The action kicks off Saturday the 8th of August. We’re looking at a 7ft swell from the west, with a 10-second period. The combined energy is moderate at 1013. But honestly, the wind is a messy cross-shore from the southwest at 16 mph, chopping it up. The forecast is calling it marginal, and I’d agree – it’s not a day to get excited about.
Sunday the 9th and Monday the 10th are more of the same, really. The swell bumps up to 8ft, still from the west, and the energy climbs a bit (1312 on Sunday morning). But that fresh cross-shore wind (19 mph) is just going to keep the surface lumpy and cross-chop. It’s surfable, but it’s work, not fun. By Monday afternoon, the wind turns cross-onshore, and the quality drops right off.
Tuesday the 11th is when it gets a bit chunky. The swell hits 8ft from the west, period stretches to 11 seconds, and the combined energy is a strong 1512. That’s a lot of power for a reef break. But the wind is straight cross-onshore, making it a lumpy, choppy mess. This is firmly in the “experts only” territory if you’re even considering it, and honestly, the conditions are so poor it’s a hard pass for paddle surfing. If you’re into kites, the setup might look more interesting with that strong wind and solid swell.
We drift through the rest of the week with the swell staying around the 7ft to 8ft mark, but the wind stays stubbornly cross or cross-onshore. The energy dips a bit mid-week, but it’s still moderate. There’s really no stand-out window until we get a change.
Now, hold on to your board, because the best of the whole forecast is a true standout. On Tuesday the 18th of August, things go glassy. We’ve got a 5ft west swell, 9-second period, and the wind goes offshore from the ESE at 3 mph in the morning, then goes glassy in the afternoon. The combined energy is moderate at 452. This is clean. This is the one. The wave comment says “expect good surf conditions,” and I’m telling you, that Tuesday is your target. The swell is a bit smaller by Wednesday the 19th (4ft), but with glassy conditions and a light offshore in the morning, it’s still a great little session for the more experienced crew, as the reef will be working nicely.
After that, the swell drops off a cliff. By Thursday the 20th, we’re down to 2ft, and the energy is weak (92). The rest of the 16-day window is a write-off with tiny, weak waves and strong, messy winds. There’s a big gap of poor conditions from the 20th right through to the end.
So, to sum it up: the first week is a grind with onshore winds and a lot of water moving around. The clear highlight is that Tuesday the 18th and Wednesday the 19th – that’s when you want to be out there. It’s not a huge swell, but it’s clean, and that’s worth its weight in gold at Ricks Reef. Keep an eye on the calendar and don’t bother with the rest.
Rusty.

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