Sunset Beach Geraldron Surf Forecast and Surf Report

Alright folks, Rusty here and I’ve been digging into the charts for Geraldton. We’ve got a 16-day window with one main spot on the radar: Sunset Beach Geraldron – a beach and reef set-up that’s fairly consistent.

The water’s sitting right around average for this time of year, 67°F, so no surprises on the temp front.

To be real with you, the first few days are a bit of a slog. Through Friday and into the weekend, the swell is rolling in around 4ft to 6ft from the WSW, but the wind is mostly cross-on or onshore. The wave energy is moderate (1075 to 1889), so there’s push, but the quality is hurt by choppy conditions. The best of this first block is going to be Sunday afternoon, where a light cross-off shore breeze from the S cleans things up with 6ft SW swell at a solid 15 seconds. That’s a runner for a go-out, but it’s still marginal.

Monday the 14th and Tuesday the 15th actually see the swell bump up to 7ft - 8ft, but the wind stays messy – clean Monday afternoon with a strong 19 mph cross-off, but that’s fresh breeze and it’ll blow the top off. The swell period is 14 seconds, so there’s decent shape, but honestly, it’s a "wait for the better session" kind of window. The energy is strong (up to 2216) but the winds aren’t cooperating for perfection.

Then we hit a flat spot from Wednesday the 16th through Thursday the 17th. Swell drops right off to 4ft - 4ft and the energy plummets (down to 546). Onshore winds mean it’s a write-off.

Things slowly pick up again on Friday the 18th. The swell gets back to 6ft to 8ft, but again, cross-onshore wind keeps it lumpy. Not a standout.

Now, the real standout is going to be Sunday the 20th of September. The forecast is pumping a big 12ft SW swell with a very long 19-second period. The wave energy is massive (9627). The problem? It’s too big for this break – the finder says as much. This is expert territory only, and at a beach-and-reef set up with a very long period, it’s gonna be an unruly beast. If you’re an absolute charger, it’s on, but for 99% of us, it’s a spectator day.

After that big pulse, Monday the 21st drops back to a more manageable 8ft from the SW at 15 seconds, but the wind is cross-onshore again. Nothing really clean until Tuesday the 22nd of September. That morning shapes up as the best pure surf of the whole run. You’ve got 8ft SW groundswell, 16-second period, light cross-off wind from the S, and clean conditions. The energy is strong at 3476, and it’s excellent for experienced surfers. It’s a Monday, so crowds might be less of an issue, but weekends can get busy here.

After that, the swells hang around 7ft to 8ft through the end of the run with periods staying in the 13-20 second range. Thursday the 24th looks promising as another long-period (20 seconds) clean morning, and Friday the 25th kicks off with clean 8ft SW swell too.

So, the two standouts in this 16-day outlook: Sunday the 20th for the sheer size if you’re an expert, and Tuesday the 22nd of September for the best all-round quality with clean conditions and a solid size.

Rusty out.
