The Lowdown
G’day, Rusty here. Looking at Racetrack, we’ve got a proper run of swell on the cards, no doubt. It starts a little average, but the ocean’s just building up its energy.
The first few days, Monday the 14th and Tuesday the 15th, have some decent height, around 2-1.8m, but the energy is only moderate (1494-1520) and the call is “marginal.” It’s not bad, but nothing to write home about. Clean with the offshore, sure, but you’re not going to be screaming.
From Wednesday the 16th through the following Saturday, it settles into a more consistent rhythm. Swell heights hover between 1.3m and 1.8m, and while it dips, the quality is better – “excellent” or “very good” calls. The winds are mostly offshore or cross-offshore, keeping things tidy. It’s good, consistent surf for the experienced crew.
But the real juice starts kicking in on Sunday the 20th. The swell jumps back to 2-2.1m, the period is a solid 16 seconds, and the energy pushes up to 2080. That’s a big step up in power, and with light offshore winds, that’s the clear standout of the first half. Proper, solid waves.
The following week is where things get serious. From Wednesday the 23rd onwards, we’re looking at consistent 2-2.1m surf with strong energy readings (2156 on the 23rd). The period is long and powerful. But the real beast is Monday the 28th. We’re talking 2.5m of SSW groundswell with an 18-second period, and the energy meter just pegs at 4835. That is a very strong, powerful swell. It’s a world-class wave for experts only. Tuesday the 29th is still solid at 2.2m with 2541 energy.
So, two distinct chapters: a fun, workable first week and a powerful, more sizable second week. The standout days are clearly Sunday the 20th and Monday the 28th. That Monday is the big one, but it’s not for the faint-hearted.
Keep an eye on it, and be ready.
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.
