The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Udo Shrine. To be straight with you, the next week and a half is looking pretty grim. We’ve got a lot of wind and rain messing things up, so you’ll want to be patient. The first real window of opportunity doesn’t open up until Friday the 11th, and even then it’s just a small, clean window. The real standout is shaping up for Wednesday the 16th, which is the one to circle on the calendar.
For the next few days, it’s a write-off. Thursday the 4th kicks off with a thumping 10 ft SSE swell, but it’s crossed up by a 12 mph SE wind, making it choppy and messy. The energy is wild (2609), but the conditions are a no-go. By Friday the 5th, the swell crashes down to 3 ft, and we’re stuck with a strong 25 mph NNE cross-onshore wind. That’s just brutal. This pattern of onshore wind and small, weak swell (energy dropping to as low as 24) continues right through until Wednesday the 10th. The water temp is about average for this time of year.
We finally get a break in the weather late on Thursday the 10th. The wind swings to the SSW, blowing cross-offshore, which cleans things up. The swell is a modest 3 ft from the SE, with moderate energy (256). This is just a teaser, though.
Friday the 11th is decent. The morning sees a 4 ft E swell with a very short period of 6 seconds, but light 3 mph SSW cross-offshore winds keep it clean. Energy is moderate (233). The afternoon is even cleaner with a clear sky and a 3 ft SSE swell. It’s not big, but it’s rideable and clean. This is the first real surfable day.
Saturday the 12th and Sunday the 13th get ruined by the NE wind returning, blowing cross-on and onshore, making a mess of the 4 ft to 7 ft swell. The 7 ft on Sunday is too big for beginners, and paired with the onshore wind, it’s just a washing machine.
Now, here’s the one you want. Wednesday the 16th morning. The wind goes glassy. Light, from the west, barely a breath. The swell is a clean 4 ft from the east, with a 9-second period, and energy is moderate (397). This is the best of the whole forecast. The afternoon stays clean with a light S cross-offshore breeze. This is the standout.
After that, we fade out. Thursday the 17th has a 3 ft E swell, but the wind is light and cross-onshore, and the period is a long 12 seconds, which can make for a straight wall at a reef break like this. By Saturday the 19th, it’s all over with a tiny 0.7 ft SSE swell and barely any energy (3).
So, to sum it up: the first week is a total loss. The best chance for a surf is the morning of Wednesday the 16th, with those glassy conditions and a clean 4 ft east swell. Friday the 11th is a decent backup for a clean, small wave session. Don’t get your hopes up for anything else.
Rusty.
