The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Narrabeen-Alley Rights over the next couple of weeks.
Straight up, we’ve got a bit of a dry spell to start. That first window on Wednesday the 22nd of July is our only real chance for a surf for a good long while. We kick off the forecast period with a clean 4ft swell from the ENE, with a period of 10 seconds and a combined wave energy of 269. The morning has a light offshore breeze, and then it goes completely glassy by the afternoon. That’s your window, folks – it’s not huge, but it’ll be clean and workable. This is the standout of the whole run. The water temp is about average for this time of year, so a decent 3/2 wetsuit will do you fine.
That’s it for the good stuff for a while, I’m afraid. After Wednesday, we slide into a long, flat spell. From Thursday the 23rd of July all the way through to late August, the swell drops away to nothing – we’re looking at tiny 0.7ft to 1ft lumps with weak energy readings between 6 and 81. It’s a solid two-week stretch of flatness, with wind that’s mostly cross or onshore. Not much to get excited about.
We get a little blip right near the end. On the 4th of August (Tuesday morning), the swell bumps up to 6ft from the SSE, with a short period of 7 seconds. That’s a heap of weak, junky energy reading 337, and it’s a beach break, so that short-period stuff will be all over the place. Tuesday afternoon cleans up a bit, but by Wednesday the 5th of August, we’ve got a 5ft SE swell with a morning offshore, going glassy in the arvo. That Wednesday is the second best day, but we’re still a long way out, so keep an eye on it. Anything over 8ft is expert-only, but this 5ft is just on the edge for beginners – you might want to sit that one out if you’re new.
Overall, it’s a pretty lean outlook. That one Wednesday the 22nd is your best bet by far. The rest is flat or marginal. For the beach-and-reef setup here, those stronger, short-period SE days could be more appealing for kite surfers than paddle surfers.
Rusty.
