The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks are a bit of a mixed bag. The reef at White Plains Beach copped a run of marginal conditions through the middle of the month, but there’s a proper payoff coming right at the back end if you’ve got the patience.
Right now, Monday the 14th is flat and weak – just 1ft of southwest groundswell with 24-second period on offer, but the combined energy is only 163, which is weak. Clean enough with a cross-off breeze, but honestly, ‘poor surf conditions’ sums it up. Tuesday through to Friday the 18th stays small – 2ft to 4ft – with the same southwest direction. The wind hangs in as cross or cross-off, so the surface stays clean, but the energy is only moderate at best. The 4ft showing on Friday morning has stronger energy (1075), but it’s lumpy and cross-chop, so not really surfable for a good time.
Over the weekend and start of the following week, it’s much of the same – small, clean, but uninspiring. A touch more size on Wednesday the 23rd, with 6ft to 6ft of short-period east swell (11 to 10 seconds) – that’s getting up there, but still only marginal due to the chop. Thursday the 24th morning is weaker and shorter-period again.
Now here’s where it gets interesting. The standout for the whole period is the last few days of September. Friday the 25th rolls in with 3ft of south-southwest groundswell, period stretching to 15 seconds, and combined energy sitting at 553 to 565 – moderate and building. The wind goes gentle cross-off, and the report says “expect very good surf conditions.” That’s a winner.
Then Saturday the 26th – that’s the one. Still 3ft from the SSW, period 15 seconds, but the wind turns glassy. Dead calm, clean, perfect. Combined energy is 521. This is the best of the lot: consistent, clean, accessible for beginners since it’s under 5ft, and that long period will wrap nicely onto the reef. It’ll be worth paddling out early. Crowds are possible here, so get in before the rush.
Sunday the 27th afternoon also looks good: light offshore from the north-northeast, 3ft, 15-second SSW groundswell, and a solid 642 energy rating. Clean lines again.
Monday the 28th morning steps it up a notch – 3ft from the SSW, period up to 18 seconds, and the combined energy jumps to 964. That glassy wind is still there. This is proper, long-period groundswell with some punch. Again, clean as a whistle. Tuesday the 29th keeps the same vibe: 3ft, 16-second period, glassy, clean.
Water temp is sitting at 81°, about 0.7° above normal for this time of year – no big anomaly, just your usual warm tropical bath.
So, take it from me: the first week and a half is skippable. Focus on Friday 25th, but the real jewel is Saturday 26th and Monday 28th. Those are your days.
Rusty out.

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