The Lowdown
Alright folks, let's be straight with you. The next couple of weeks are looking pretty bleak. We've got a long stretch of tiny, weak surf ahead, and it's going to take a while before anything worth paddling out for shows up.
Right now, the energy is just not there. The combined swell energy is sitting in the doldrums, with values like 27 and 42 (weak), and the swell is a short-period, wind-driven 2ft to 2ft. It's just messy and gutless. The wind is cross and cross-on, so it's not even clean. You're looking at a week of this, honestly. Through the 12th, we're seeing those weak numbers (24, 14, 16), with the swell barely scraping 2ft. There's a day or two with a bit of offshore breeze, like Saturday afternoon the 8th, but it's still just 2ft of short-period slop. Not worth the wetsuit.
The first real change comes around the 15th and 16th. The swell direction swings around to the east, and we finally see some size, but it's still not good. The energy picks up to 96 and 106 (moderate), and the swell gets to 4ft, but the period is still short – only 5 or 6 seconds. That's just wind chop. It's going to be lumpy and hard to surf. The wind is onshore and cross-onshore, so it's going to be a battle. This is when the conditions might start looking more interesting for the kite crew than the paddle crew.
The standout, if you can call it that, is the 17th. The swell is 4ft, but the period is still only 6 seconds, and the energy jumps to 200 (moderate). The wind is cross-onshore, so it'll be a bit lumpy, but there might be some fun, punchy waves if you can find a bank. It's not a classic, but it's the biggest surf we've got on offer. The 18th is a step down, with 3ft and shorter period.
After that, it fades back into the gutter. The 19th and 20th see the swell drop back to 2ft with a touch more period (8 seconds), but the energy is still weak (43, 51). The 19th morning is glassy, so it could be clean, but it's just not enough to get excited about.
So, what's the call? The best of a bad bunch is the 17th. It's got the most size and energy, but it's not clean and the period is short. Look for a protected bank or a spot that handles wind swell. Other than that, it's a lot of flat, small, and bumpy days. For a beginner, even the 4ft – 4ft days might be a bit much, but the rest of the time you're just fighting for ankle-biters. Hang loose, and maybe work on your paddling.
