Cox Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about Cox Bay in feet and miles per hour.

We’ve got a slow start, but there’s a real gem waiting for us mid-week next week. The first few days are pretty marginal, with small swell and tricky winds, so don’t rush for your wetsuit just yet. Things pick up towards the end of the first week and into the second, but you’ll need to pick your windows carefully as the wind can get messy.

Tuesday 15th September kicks off with a glassy morning—dead calm, slight air—and a tiny 1ft swell out of the southwest with a very long period of 17 seconds. The energy is moderate (243). This is a great little window for a longboard or a funboard. It's clean, but tiny.

Wednesday 16th and Thursday 17th see a bump in size to around 3ft to 5ft, but the swell is from the WNW and period drops to a short 7-8 seconds. The wind is cross or cross-onshore at about 6 mph, so it’s going to be a bit bumpy. Not worth paddling out for unless you’re desperate.

Friday 18th September morning is a standout for this early period. It’s small at 1ft, but the swell is a long-period 21 seconds from the southwest, and the wind is a clean cross-offshore breeze at 6 mph. The combined energy is moderate (383), and conditions are clean. For a small-wave session on a log, this is your best bet until next week.

After that, we hit a dry spell. Saturday 19th through Monday 21st blow up with onshore winds. Sunday the 20th sees swell build to 2ft but it’s onshore and ugly. Monday the 21st gets messy with a 7ft to 8ft swell from the west, but the wind is a stiff cross-onshore breeze at 15-22 mph. The energy is very strong (over 2000), but it’s choppy and lumpy. This is more of a kite-surfing setup than a paddle session.

Now for the real highlight. Tuesday 22nd September morning is a nice recovery. The swell drops to 5ft from the west with a moderate 10-second period. The wind is a clean cross-offshore from the SSE at 6 mph, giving us clean conditions. The energy is moderate (887). This is a solid, fun day.

BUT the standout of the entire forecast is Wednesday 23rd September morning. Get ready. The swell is a solid 6ft from the west, with a nice 11-second period. The wind is glassy—absolutely dead calm from the WSW at 6 mph. This is excellent surf for experienced surfers. The wave energy is strong (1137), and you’re looking at clean, powerful, lined-up waves at Cox Bay. This is the one to circle on your calendar. The water temp is about average for the time of year, so don’t expect any surprises there.

After that, Thursday 24th gets a bit chunky again with a 8ft swell, but wind turns onshore, making it choppy. Friday 25th is a write-off with strong onshore winds at 15-22 mph and a massive 12ft swell—that’s expert-only territory and it’s going to be a mess.

The following weekend, Saturday 26th and Sunday 27th September, sees the swell back down to a manageable 3ft to 4ft with clean, light winds at 6 mph. Good for a relaxed session. The very end of the month, from Monday 28th to Wednesday 30th, has a series of small, glassy mornings with 2ft to 3ft swell. Nice and clean for a quiet, fun surf if you’ve got a longboard.

Bottom line: if you’re picking one session, make it Wednesday 23rd morning. It’s clean, powerful, and glassy—that’s the one. The rest is small or windy.

Rusty.
