The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
We’re looking at a pretty grim run at Cap Sim overall. The water is running way colder than usual for this time of year, a solid 4° colder than normal, so that’s going to be a shock to the system right off the bat. The first few days are a write-off with strong, cross-off winds and messy, marginal surf. Honestly, the first real chance for a surf doesn't show up until Friday afternoon, 4th September. That’s a full week of waiting.
Friday afternoon sees a moderate offshore breeze setting in, cleaning up a 5ft swell from the north. The period is short at 7 seconds, so it’ll be a bit weak and wonky, but it’s the first decent window. The combined energy is moderate at 231. It’s not a standout, but it’s a start.
Saturday morning, 5th September, is a better bet. The wind is still offshore from the NE at 15 mph, keeping things clean. The swell holds at 5ft from the NNW, with a similar short period. The combined energy pushes up to 323 (moderate). This is probably the most reasonable session for a confident surfer, but it’s not going to be a classic.
Then we get to Sunday morning, 6th September. The wind drops to glassy, and the swell drops to 3ft from the north. Period is still short at 7 seconds. The energy is 252 (moderate). This is your best chance for a proper relaxing, clean surf. It’s small, but clean. No crowds to worry about here, but the break is inconsistent, so you’ll be sitting and waiting. It’s a beautiful morning for a paddle.
After that, it goes quiet again. The swell picks up a bit on Monday 7th and Tuesday 8th, but the wind is too strong and cross-off, making it a mess. The long period swell (11-13 seconds) that shows up doesn’t help because the direction is off and the wind is ruining it. Not worth the effort.
The second week is a total bust. Wind is howling, mostly strong to near-gale force, and the swell is tiny or blown out. There’s nothing to recommend. It’s a long, dry spell.
So, to wrap it up: The standout is the glassy Sunday morning, 6th September. It’s small, but it’s clean. The second best is the offshore Saturday morning, 5th September, for a bit more size. Other than that, it’s a waiting game.
Rusty.

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