The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for Udo Shrine.
Honestly, it’s a bit of a tough outlook for the next two and a half weeks. We’ve got a big gap at the start with nothing to get excited about until Tuesday the 15th. The water temperature is sitting right around 82°, which is pretty much normal for this time of year, so no surprises there.
The first real glimmer of hope comes on Tuesday, September 15th, in the morning. We’ve got some clean, glassy conditions with a 4ft swell coming out of the ESE. The combined energy is moderate, sitting at (376), and while the period is short at 9 seconds, the glassy wind is the big winner here. That’ll make for clean, fun little surf on the reef. This is your best bet in the whole period—small and clean, but very surfable.
After that, things go downhill fast. The wind gets onshore and the surf gets messy. There’s a massive pulse of energy later in the week (September 20-22), with swell jumping to 16-20ft and combined energy shooting up to over 10,000 (10063-14325). That sounds huge, but with brutal onshore winds from the NE and ENE (22-50 mph), it’s going to be a complete washout. That kind of size and wind is more for the kite crew than paddle surfers. The period on the 20th is a very long 15 seconds, which at a reef setup could offer some shape, but the wind will ruin it.
We get a brief cleanup on the 23rd with a cross-offshore WNW wind and a small 3ft swell, but the energy is weak (129) and it’s still marked as poor. After that, into the last few days of September, it’s all tiny, weak, and onshore. Nothing to plan a session around.
So, to wrap it up: the standout is without a doubt Tuesday morning, September 15. It’s not big, but it’ll be clean and fun at Udo Shrine. For the rest, you’re better off waiting for a change in the forecast.
Stay salty,
Rusty
