The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Floreat groyne. We’ve got a real mixed bag over the next couple of weeks, with some solid groundswell windows but plenty of wind to dodge.
The opening act kicks off on Wednesday the 12th with a pulse of WSW swell just under 6 ft, but a 9 mph cross-shore wind from the SSW is going to put a bit of chop on it. The water’s sitting at 63°, which is a bit colder than normal for this time of year. It’s a marginal session, not the best start.
Things look up on Thursday morning the 13th though. The swell pushes up to 6 ft from the WSW, with a 16-second period, bringing proper groundswell energy. The wind goes glassy off the land from the ENE at just 3 mph. That’s clean, lined-up surf. The combined energy is strong at 1787, and this is the standout window for the week. It’s a bit meaty for beginners though, over that 5 ft mark.
Friday the 14th keeps the good times rolling. The morning sees a 7 ft WSW swell, 16-second period, with a light cross-offshore breeze. The afternoon is the real gem: glassy conditions with the wind dropping to 3 mph from the SSE, and the swell easing slightly to 6 ft. The water's still that same bracing temperature. This is the pick of the week for clean, groomed waves.
Saturday the 15th drops off a bit. The swell is still 6 ft, but the wind picks up from the NE at 12 mph in the morning, making it a cross-offshore. The afternoon goes cross-on, which is a no-go for clean faces. Sunday the 16th is a similar story – decent 6 ft to 7 ft swell, but a moderate 12-15 mph cross-offshore wind keeps it from being perfect. It’s surfable but not the best.
Then things get wild. Monday the 17th turns into a write-off. Morning winds are a strong 19 mph cross-onshore, and by the afternoon a 31 mph onshore gale from the WSW arrives with a massive 12 ft swell. That’s a full-on washing machine, only for the crazy ones. The combined energy hits 5970 – that’s serious power. The swell keeps building into Tuesday the 18th, with 12 ft sets, but it’s just too big for this spot. The wind is onshore again, making it a mess.
We get a bit of a lull, then there’s a promising long-range standout on Saturday the 22nd. The morning has a 8 ft WSW swell, 14-second period, and a glassy cross-offshore breeze from the SSE at just 3 mph. The combined energy is 2698, strong and clean. This is worth keeping an eye on, but it’s a week and a half away, so don’t book the day off yet. The rest of the second week is a mixed bag of onshore winds and messy conditions, with the swell fading back to 3 ft to 6 ft by the 27th.
Overall, you want to be on the water Thursday morning the 13th or Friday afternoon the 14th. The 22nd is the real long-range hope, but treat it as a promising rumour until we get closer.
Stay frothy, Rusty.

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