The Lowdown
Alright folks, Rusty here. Let's take a long look at what Big Beach has on offer for the next couple of weeks. It’s gonna be a quiet spell with a few bumps in the road, so don't go expecting any fire just yet.
The overall pattern is one of fading swell and small, weak surf. We kick things off with a few waves, but nothing that’s going to have you calling in sick. The water temperature is sitting at 81°, which is pretty much spot on for this time of year—no surprises there.
We start the run on Sunday, September 6th. The afternoon sees a 5ft SW swell, with a 12-second period. The combined energy is moderate at 827, but winds are a cross-off E at 12 mph. It’s surfable, but the forecast calls it marginal. That's our starter.
Monday the 7th is a bit of a mixed bag. The morning drops to 3ft, but the period jumps to a very long 17 seconds from the SSW. That’s a proper groundswell, but with only a moderate energy reading of 1019, it’ll be slow and fat at a beach break like this. The afternoon picks up again to 5ft at 12 seconds (1429 energy), but the wind is still cross-off. It's clean, but nothing is firing.
Tuesday the 8th is a write-off. The wind swings cross-on, and the swell gets a bit lumpy and choppy. Not worth a paddle.
Wednesday the 9th drops right down. We're looking at 3ft from the SSW with a 14-second period in the morning (404 energy) and clean conditions under a cross-off ESE breeze. It’s small but clean—could be a fun log session for the absolute beginner crew.
From Thursday the 10th through to the end of the first week and into the second, it gets tiny. We’re talking 1ft to 2ft of swell for days. The energy drops right off into the double and low triple digits. The conditions stay clean, often with light or even glassy winds, and on Monday the 14th, the morning is glassy with a NE breeze. But there’s just no swell to work with. This is a long, flat gap.
The standout window for the whole forecast is the period starting Monday, September 14th, through to Wednesday, September 16th. The morning of the 14th is flat, but the afternoon sees a 2ft SW swell with a massive 22-second period. The energy jumps to 278. It’s tiny, but that period is insane. It’ll be super clean, and the sets will be super long between. Tuesday the 15th is slightly better with 2ft, and Wednesday the 16th peaks at 3ft. For this whole quiet stretch, that’s the best on offer.
If you had to pick one, I’d say the Wednesday, September 16th, morning session at Big Beach (Maui). You’ve got 3ft from the SSW, a long 18-second period, clean conditions with a light ESE breeze, and a moderate combined energy of 439. It’s small, but it’s the most consistent wave in an otherwise flat run. Don’t expect barrels, just clean little runners for a longboard.
After that, the surf tries to build a little towards the final weekend of the 19th and 20th, but it’s still hovering around the 3ft to 3ft mark. The energy picks back up into the moderate range (around 500-600), but it’s still marginal. It’s not a total blank, but it’s close.
So there you have it. A quiet two weeks, with a small but clean window mid-month being the best you're going to get. Keep an eye on it—forecasts can change.
Rusty.

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