The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way.
Honestly, for the next week and a half, it's a bit of a bust. We've got a long, flat spell ahead. From now through to the morning of September 4th, there's just no surf worth paddling out for at Slip Point. The water is sitting at a very unusual 53°F, which is 6°F colder than normal for this time of year, so that's a shock to the system if you do go for a dip.
A glimmer of hope finally shows up on the morning of Friday, September 4th. We'll see a pulse of new swell arrive, coming from the WNW. The waves will be a small 3ft with a period of 8 seconds, and the combined swell energy will be moderate at (120). What really makes this a standout is the wind. We'll have a crisp ESE breeze blowing at 16 mph, which is clean offshore. Conditions will be clean right through into the afternoon, with the wind easing slightly but still holding offshore.
The following morning, Saturday, September 5th, the swell drops back to 2ft but the wind is still favorable. A moderate offshore breeze of 12 mph from the ESE will keep things clean. It's not big, but with that wind, it will be rideable.
Given the persistent onshore and cross-onshore winds we see for the rest of the period, that window on the 4th and 5th is your best bet. Stick to those early sessions. This is a place for advanced surfers on its best days, so beginners should steer clear even when it's small.
Rusty.
