Table - best surf conditions forecast for Castlepoint - The Gap over the next 16 days.
Alright mate, let’s talk about Castlepoint – The Gap in proper units.
The first few days are a total bust. Cross-shore wind, lumpy chop – no reason to get wet. You’re sitting through a dry spell until Sunday the 12th.
That Sunday morning finally shows some promise. It’s glassy with a light offshore from the WNW, and a small 3ft swell rolling in from the SSW. That’s a long-period groundswell around 13 seconds, so it’s got some push to it, but it might wall up a bit on a beach break. The water’s about 55°, which is normal for this time of year.
The session you want is Saturday the 18th of July. That morning is firing. Offshore wind from the WNW at just 6 mph, with a clean 6ft south swell. The energy is pumping, and the call is "expect very good surf conditions". That’s your morning. Expect a few others will have the same idea, though.
Sunday the 19th is a monster – a near 10ft south swell with a gale blowing. That’s a hard pass for paddling, maybe give the kite a service. The following week settles down. The 21st and 22nd see solid 8ft clean waves on the Tuesday afternoon and Wednesday morning, but when it pushes over 8ft, that’s expert-only.
The last few days of the run, the 23rd through 25th, drop off to 5ft or less, with some clean mornings worth a look before the wind gets messy.
The standout remains Saturday 18th morning. Clean glass, solid 6ft, offshore wind. Get it.
