The Lowdown
Alright, Rusty here. Let’s see what’s cookin’ for the local stretch.
Honestly, the next week and a half is a pretty flat and quiet affair – a lot of small, weak surf with wonky winds and barely enough push to get you excited. The combined swell energy hangs around weak to moderate (36 to 165), and most of that is messy, short-period windswell (4 to 6 seconds). For the first 10 days, you’re looking at a lot of cross-on or choppy conditions, with only a few clean windows that still have tiny waves. The water’s sitting at 64°F – a touch warmer than usual for this time of year, so that’s a nice bonus if you’re paddling out in a spring suit.
Thursday morning the 20th offers *surfable waves but very ordinary conditions* with 3 ft of NE swell and a clean, cross-off breeze, but it’s still weak (combined energy 70). Monday the 24th morning goes glassy with a bit of south swell (10 second period) but only 1 ft – more of a longboard chill session. Wednesday the 26th morning is another glassy moment with 2 ft and a period of 8 seconds (combined energy 65). These are okay for a quick knee-paddle, but nothing to write home about.
Now, the real standout – and it’s worth the wait – comes in on Sunday the 30th. This is where it gets interesting. Morning brings a glassy, dead-calm session with 7 ft of south-southeast groundswell rolling in at a very long 14 seconds. Combined energy is a strong 1636. This is *excellent surf conditions for experienced surfers* – well overhead, powerful, and clean. The period is long, so this swell will love a bank or a river mouth like Moruya Rivermouth, though it might run a bit straight on the beach. Still, this is the best bet of the whole 16 days. The Saturday afternoon before it (29th) shows 6 ft of the same swell starting to fill in, but with a cross-on breeze, so the Sunday morning glass is the one to circle on your calendar.
Monday the 31st drops back a bit, with 4 ft of SSE swell but the north-northeast wind starts to spoil it.
So, in a nutshell: a long, flat first 10 days with only tiny, marginal windows, then a solid pulse of clean, expert-level south groundswell arrives on Sunday the 30th morning. That’s the one.
Rusty.
