The Lowdown
Alright, Rusty here, let’s look at what’s shaping up for Sunset Left.
Honestly, the next week and a half are a bit of a grind. We’ve got persistent moderate cross-shore and cross-onshore winds messing up the surface, and the swell is choppy and inconsistent. The water’s sitting at 80°F, which is pretty much bang on average for this time of year, so no surprises there.
We start Wednesday morning, July 22, with a 4ft SSW swell, but it’s coming in with a 16 mph SE cross-breeze, so it’s a messy, choppy affair. That pattern sticks around through the rest of July and into the first few days of August. Afternoon sessions on Friday, July 24, and Tuesday, July 28, are barely worth a mention – just marginal surf with questionable tide conditions and lumpy cross-chop.
The real story is the second week. From Saturday, August 1, things start to look more promising. The wind drops right off to a light breeze, and we start seeing some proper groundswell. Sunday morning, August 2, has a 5ft SW swell with a 16-second period and light offshore wind – that’s clean. The wave energy is ramping up strong, hitting 1306 (moderate to strong). By Wednesday afternoon, August 5, we’re looking at a standout: a solid 7ft SW swell, 18-second period, glassy conditions with light cross-onshore breeze, and the combined energy is a massive 3159 (very strong). That’s the pick of the whole forecast. This is a long-period groundswell, so it’ll be breaking a bit straight on the beach, but for a reef setup like Sunset Left, it’s going to unload nicely. This is advanced territory at that size, and it gets even bigger Thursday morning, August 6, with 8ft swell and 3263 energy – that’s expert-only stuff.
So, if you can wait, the first week of August is where it’s at. The first week and a half are a write-off, but hang in there.
Rusty.

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