The Lowdown
Alright, Rusty here again, same outlook but in feet and miles per hour for you.
First real surf we see is on Thursday 10th September. There’s a 4 ft NW swell, energy is 311, and the morning has a nice light offshore breeze from the ESE at 6 mph, keeping things clean. Water temp is 74°, way warmer than usual for this time of year. The afternoon goes cross-onshore from the NW and chops out.
Friday 11th September is small, only about 2 ft from the NW, but the morning is glassy – barely any wind from the N at 3 mph. It’s clean but tiny, energy is only 83. Afternoon gets bumpy.
Saturday 12th September is the same story: 2 ft NW swell, glassy in the morning, choppy by afternoon. Sunday 13th September morning picks up to 4 ft with a 13-second period from the NW, energy at 545 (moderate). Wind is offshore from the WSW at 6 mph – clean lines for the reef. Afternoon gets a bit messy.
The pick of the first week is Monday 14th September morning. Dead calm wind from the SSW at 0 mph, glassy as it gets, with a 4 ft NW groundswell at 11 seconds. Energy at 399, so there’s some push. Perfect conditions.
Then we hit a quiet patch from Tuesday 15th through Thursday 17th – small, weak, onshore junk.
Friday 18th September morning bounces back with glassy E wind at 3 mph, 3 ft NW swell. Clean fun. Saturday 19th September morning is also clean with a light offshore E breeze, 4 ft NW swell.
The big standout is Sunday 20th September morning. 7 ft NW swell, period 9 seconds, energy at 680 (strong). Wind is NE at 3 mph, glassy. That’s too big for beginners but pumping for everyone else. Afternoon hits 10 ft and cross-onshore – expert only.
Monday 21st September is huge – 12 ft NW with 10 to 13-second periods. Energy is 2262 and 3459 (very strong). Expert-only, with onshore wind making it a mess.
Wednesday 23rd September morning is glassy, 7 ft NW at 11 seconds, energy 1004 (strong). Good for experienced surfers, too big for beginners.
Thursday 24th September morning is a weird one – 3 ft NW with a 17-second period. Dead calm NE wind, glassy, but that long period will make it wall up nicely on the reef. Special small session.
Friday 25th September sees 7 ft NW swells but with onshore wind, so it’s rough and challenging.
Overall, the standout is Sunday 20th September morning for the size and clean wind. Backup is Monday 14th September morning for perfect glass. The second week looks promising but less certain, with a lot of big, windy swell.
