The Lowdown
Alright folks, Rusty here. Let's cut straight to it. We’ve got one spot firing, and it’s a long, consistent run of quality swell.
The whole 16-day window is dominated by solid, clean surf at Racetrack. This advanced reef and point break is exposed to the swell and the setup looks prime. We kick off right away, no waiting around.
Monday afternoon (7th September) starts us off with a clean 7ft SSW swell. The offshore wind is holding and the wave energy is already strong at (1695). The water temp is 79°, which is about average for this time of year, so the spring suit is fine.
The pattern locks in through the first week. Tuesday (8th) and Wednesday (9th) see the swell holding 6ft to 8ft from the SSW, with cross-off breezes keeping things clean. Energy is building into strong territory, hitting (3469) on Tuesday afternoon. This is quality, powerful groundswell, with periods stretching from 13 to 18 seconds. That long period (over 11 seconds) means proper energy and more defined sets, perfect for a reef setup like Racetrack.
Thursday 10th and Friday 11th keep the goods coming. We’re looking at 7ft to 6ft SSW to SW groundswell, and the wind turns offshore again. The surf stays clean and consistent. The combined wave energy is still at strong levels, around (2022) on Friday morning.
The second weekend, Saturday 12th and Sunday 13th, the swell dips slightly but stays rideable at 5ft to 7ft. Offshore winds are forecast for Saturday, making for a beautiful morning session. Expect a bit more crowd factor here, as Racetrack is marked as ‘always’ busy, but that’s the price of consistency.
From Monday 14th through the following Friday 18th, it’s more of the same classic run. Moderate offshore winds from the ESE and SE, with swell holding steady between 6ft and 7ft from the SSW to SW. The wave energy continues to be strong, with figures like (2301) on Friday morning. The wind is a gentle offshore breeze, resulting in glassy conditions.
Now, the real standout is Sunday 20th September. That’s the day to circle on your calendar. The morning session is looking absolutely pumping: a solid 10ft SW groundswell with a 16-second period. The combined wave energy rockets to (3990). This is big, powerful, and clean with gentle offshore wind. This is expert territory, though – over 8ft is for experienced surfers only at a spot like this.
The run finally starts to ease off by Tuesday 22nd September, dropping back to 5ft to 6ft SSW swell with lighter energy (1077). It’s still surfable, but you can feel it winding down.
Overall, if you’re an advanced surfer, this is a dream forecast. One break, consistent swell, mostly clean winds, and a serious power day on the 20th. It tends not to stay this good for long, so get on it.
Rusty.

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