The Lowdown

Alright, let me talk you through what’s coming up for our local stretch. It’s gonna be a wild ride, and you’ve gotta pick your moments.

We’ve got a massive pulse of energy rolling in, but the problem is, it’s going to be way too big for this spot for a couple of days. Tuesday the 18th sees a serious 12 ft swell from the west-southwest, with a very long 16-second period. The combined energy is enormous (6079). This is expert-only territory if you’re brave, but honestly, it’s probably just going to be a washing machine. The water is sitting at 63°, which is a bit colder than we’d expect for this time of year.

Wednesday the 19th is still messy with a 8 ft to 10 ft swell and onshore winds. The surf is poor, and the wind is junk. Best to give it a miss.

Now, Thursday the 20th morning is the standout window. The swell drops to a still-chunky 8 ft from the west-southwest, but the wind goes glassy with a light southeast breeze. The combined energy is strong (3594), and it’s going to be clean for the experienced crew. This is your best chance to get some proper waves without the wind messing it up. Crowds are possible here, so get in early.

Friday the 21st morning is also worth a look with a 7 ft west-southwest swell and light offshore east winds. Clean conditions, but the energy drops a bit (2049). Still good for a session if you’re keen.

Saturday the 22nd morning has a 6 ft swell and clean conditions with a light cross-offshore breeze. This is still good for experienced surfers, but it’s not as powerful.

From Sunday the 23rd through to the end of the month, it’s a real mixed bag with onshore winds and choppy, messy conditions. The swell drops off and the quality tanks. You’ll have a few mornings like Monday the 24th with clean conditions on a 6 ft swell, but the wind shifts onshore by afternoon. Tuesday the 25th gets real nasty with a strong onshore breeze up to 28 mph – that’s kite-surfing weather, not paddle surfing.

Into the first week of September, things start to look a little more promising. Tuesday the 1st of September morning brings a clean 7 ft west-southwest swell with light cross-offshore winds – another good session for the experienced surfer. The confidence is higher for the near-term calls, so keep an eye on that one.

Overall, if you’re looking for the best of the bunch, it’s Thursday the 20th morning with that glassy, clean 8 ft swell. Second best is Friday the 21st morning. After that, you’re waiting on windows that are more marginal until the start of September.

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.
