The Lowdown
G’day, Rusty here. Floreat groyne’s the only spot on the radar, and it’s got a real mix of clean windows and wild, blown-out days. The water’s sitting at 17° which is a touch cooler than usual for this time of year. That long-period groundswell from the WSW is pumping in some serious energy—we’re talking 3681 (strong) on Tuesday afternoon, but the wind is a messy cross, making it more of a close-out session for the experienced crew. Wednesday morning, the 12th, is where it’s at: glassy conditions, 7ft swell from the WSW at 14 seconds, and the energy’s dropped to 1670 (moderate). That’s a proper window for experienced surfers to get some clean, lined-up waves on the groyne. Thursday morning the 13th holds the same standard—clean 6ft with a cross-off breeze and energy at 1787 (moderate). Friday the 14th is a standout with two clean sessions: morning sees 7ft and 1904 (moderate) energy with a light cross-off, and afternoon keeps it going with 6ft and 1766 (moderate) energy. That’s as good as it gets for the week—two tidy sessions in a row. Saturday the 15th drops off with a cross-on wind and only 994 (weak) energy by the arvo. Sunday the 16th morning is messy, but the afternoon bounces back with 7ft, 2084 (moderate) energy, and clean conditions—another solid hit for experienced surfers. Monday the 17th is a write-off with onshore wind, and Tuesday the 18th sees 8ft onshore slop. The following Friday the 21st is a rain-swept mess with 19 mph cross-shore winds. Then, a light at the end: Saturday the 22nd morning delivers 8ft, 3277 (strong) energy, clean with a cross-off breeze—that’s the best of the second week, but it’s a long way out, so keep an eye on it. Wednesday the 26th morning brings a glassy 5ft with 1097 (moderate) energy, small but clean for a fun morning. All in all, the clear winners are Wednesday the 12th morning and Saturday the 22nd morning. Crowds can show up here sometimes, so pick your window.

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.
