The Lowdown
Alright surfers, Rusty here. Let’s break down what Floreat groyne has in store over the next couple of weeks. It’s a mixed bag, but there are windows worth chasing.
Right now we’ve got a big 10ft WSW groundswell hitting on Friday (4th), but the cross-onshore wind is ruining it. The energy is through the roof (3354), which means power, but it’s lumpy and messy. That’s a pass for me unless you’re kiting.
Through Saturday, the swell drops but the wind stays onshore, so the quality stays low.
The big turn is Monday (7th). The wind goes offshore and clean all day. Morning sees a clean 8ft WSW swell with a very long 16-second period, and combined energy is 2888. That’s proper groundswell with great shape, but it’ll be steep and powerful – better for experienced surfers. The water is a bit colder than average at 64°, so suit up. This is the standout of the first week.
Tuesday (8th) afternoon is also excellent – offshore breeze, 8ft swell, moderate wind, clean faces. Crowds are possible, but it’ll be worth sharing a few waves.
Second week brings some chaos. Sunday (13th) throws up a massive 13-15ft swell, but the wind is howling onshore. That’s too big and blown out for surfing – a kite-only day.
Tuesday (15th) morning is another gem. A clean 8ft WSW swell with light offshore wind and blue sky. That’s a proper dawn patrol session for confident surfers.
Wednesday (16th) morning is much smaller at 4ft but glassy with offshore wind – longboard heaven.
Then the swell picks up again Thursday (17th) but the wind turns cross-onshore, so the quality drops. By Saturday (19th), a near-gale westerly blows everything out. Don’t bother.
Best call: Monday (7th) for the best quality big waves, and Tuesday (15th) for a solid backup. Mark the calendar.
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. If you surf the same spot (Floreat groyne) 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 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.
