Cox Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s look at what’s shaping up for Cox Bay.

The water temp is sitting at 15°, which is bang on normal for this time of year—nothing to worry about there.

We’ve got a pretty quiet start to the period. The first few days are small and choppy. Saturday morning (29th August) has a tiny 2ft swell from the SSW with a slight cross-on breeze, but it’s a marginal one with weak energy (474). Saturday afternoon is a write-off – onshore wind and poor conditions. Sunday morning (30th) is where it starts to perk up a bit: 3ft, clean cross-off wind, and a 17 second period groundswell that’ll give the waves a bit of push. The combined energy is moderate (511). That’s a fun little window for a longboard or a fish.

Sunday afternoon also stays clean, but the swell backs off a fraction. Monday (31st) and Tuesday (1st September) are mixed—some clean windows, but the swell is still small and inconsistent. The period dips to 14 seconds by Tuesday, losing some grunt.

Then Wednesday (2nd) sees a bump in size: 5ft to 5ft from the west, but the period drops to 8–10 seconds – that’s short-period windswell, less shape. The energy picks up to 610 by Wednesday arvo, but the wind is cross-on, so it’s a bit messy. Thursday (3rd) afternoon is a standout: glassy conditions, 4ft west swell, and clean faces. That’s one to pencil in.

Friday (4th) has a weird spike – 2ft from the SW but with an 18-second period and energy of 649 – that’s a long-period groundswell, but it’s tiny and the wind is onshore, so don’t get too excited. Saturday (5th) afternoon looks glassy again with 3ft from the SSW and decent energy (553). That’s another clean, fun session.

Now, the real standout is Tuesday, 8th September. Morning has 6ft from the west with a clean cross-off breeze and big energy (1026). That’s a solid, powerful swell for experienced surfers. But the absolute gem is Tuesday afternoon: glassy, 7ft west swell, 11-second period, and energy through the roof at 1357. That’s a proper session – excellent conditions, but it’s pushing into expert-only territory size-wise. The west swell direction is a good match for Cox Bay’s exposure. It’s a beach and point setup, so that long-period groundswell might hold up well on the point if the tide cooperates.

After that, Wednesday (9th) drops off fast with onshore wind, and the rest of the second week fades into small, choppy, or onshore conditions. There’s a brief glassy window on Thursday morning (10th) with 3ft, and another on Friday morning (11th) with 3ft from the SW and a 17-second period – clean but small. The last few days are a write-off with strong onshore winds.

Bottom line: the best bet is definitely Tuesday 8th September – the afternoon glass-off with 7ft west swell is the standout. Second pick is Saturday 5th September afternoon for a smaller, clean session.
