The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
We’ve got a bit of a slow start, but some real quality is building towards the end of the first week and into the second. The first few days are a bit messy with onshore winds, but we’ll see some clean windows open up.
Friday 11th September is a write-off, to be honest. A clean 3ft WSW groundswell (19 seconds) is rolling in with a moderate 12 mph cross-offshore breeze, giving it a clean look, but the wave comment says it’s marginal. The afternoon turns cross-on and choppy with a 4ft swell. The combined energy is still strong (1345 and 1599), but the wind just isn’t playing the game.
Saturday 12th and Sunday 13th are pretty poor. The swell builds to 6ft-7ft on Saturday, but it’s a messy cross-on or onshore wind from the WSW, making for choppy, poor surf. The energy is high (1791-2758), but it’s not for paddling.
Monday 14th September is where we start to see a change. The morning brings a clean 7ft groundswell from the WSW (14 seconds) with a light 6 mph offshore breeze from the East. This is clean, solid surf. The comments say "excellent surf conditions for experienced surfers" – and that’s exactly right. The wave energy is strong (1969). This is a standout for the week. The afternoon gets a bit messy with a strong cross-shore, so get in early.
Tuesday 15th September is another cracker. Morning session with a 7ft WSW swell and a gentle 9 mph offshore breeze from the ENE. The conditions are clean and the surf is solid. Another top pick for the experienced surfer. The combined energy is still strong (1704).
Wednesday 16th and Thursday 17th see the swell drop off and the wind turns onshore again, leaving us with choppy, small surf. Not worth the paddle.
Friday 18th September is a no-go. The wind kicks up to 22 mph, making it a lumpy, fresh mess. The swell is there but the quality is gone.
Saturday 19th September brings a massive pulse. A 13ft-15ft swell from the WNW, but it’s too big for this break. The wave energy is extremely strong (3913-4589). This is expert-only territory, and even then, the onshore wind will make it a beast. For the average surfer, this is a day to watch from the beach.
Sunday 20th sees the swell drop back to 6ft-6ft, but the wind is cross-on, leaving it choppy and marginal.
Monday 21st September is the absolute standout of the entire forecast. The morning is a dream: a 10ft groundswell from the WSW (15 seconds) with glassy conditions. The combined energy is massive (3866), and the conditions are described as "excellent surf for experienced surfers". This is the best window we have. The afternoon gets a bit of a cross-on breeze, but the morning glass is the one to chase.
Tuesday 22nd September is still very good. A 8ft WSW swell with a clean 16 mph offshore breeze from the ESE. The surf is solid and clean. Another great option for the experienced surfer.
Wednesday 23rd to Friday 25th September the swell drops to 3ft-5ft, but the wind stays offshore from the East. The surf will be clean and small, perfect for a log or a fun board. The energy is moderate (485-1362), but the conditions are good.
Saturday 26th September ends the run with a small, clean 4ft swell and light cross-offshore winds. A nice way to finish.
So, to wrap it up: the best surf on offer is the Monday 14th September morning and the Monday 21st September morning. The 21st has the biggest, glassiest conditions and is the true standout. The Tuesday 15th and Tuesday 22nd mornings are also excellent, clean options. The rest of the period is a mix of small, clean waves or big, messy ones.
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.
