The Lowdown
Alright, Rusty here. Let’s talk about Spanish Bay-South Moss.
It’s a bit of a slow start for the next couple of weeks, to be honest. We’ve got some swell, but the wind and the quality are just not playing ball. The first real push of energy comes on the 19th, but it’s a frustrating one. We’ve got a 2 ft swell from the SW with a really long 17-second period, which is great for a point break, but the cross-on wind from the West is going to leave it choppy and messy. The water is sitting at 57°, which is actually a touch cooler than average for this time of year, so you’ll want a decent suit.
The pattern stays pretty similar through the 20th and 21st. The swell stays small, around 2 ft to 3 ft, and the wind, while light, is mostly cross-on. The combined swell energy is moderate (423 to 665), but it’s not translating into clean waves. There are a few mornings on the 22nd and 23rd where the wind goes offshore from the NW, but the swell is still small and the period drops, so the waves are a bit weak.
Now, the real standout is the period from the 25th of July right through the start of August. The swell size jumps up, and the energy numbers get big. On the 25th, we see a 3 ft swell from the SSW with a 21-second period, and the combined energy hits 1269. That’s strong. The wind is offshore from the NW on the morning, which is perfect. This is the best bet. The wave quality is still marked as marginal, but the ingredients are there for a clean, lined-up wave at this spot. The crowd factor is listed as "sometimes", so you might have a few others out, but it’s not going to be a circus.
The 27th and 28th see the swell build even more. On the 28th, we’re looking at a 7 ft swell from the NW, but the period drops to a short 9 seconds. For a beach break, that’s going to be a bit crumbly and hard to handle. At 8 ft on the afternoon of the 28th, it’s going to be big and punchy, only for the experts. The wind is offshore, but the short period makes it a bit of a washing machine.
The 29th to the 31st of July keeps the size up, around 5 ft to 7 ft, but the period stays short (9 seconds) and the wind goes cross-on. The energy is high (1209 to 1273), but the quality is poor. For a beach-and-reef setup like this, it’s really only going to look good for the kites.
Come the 1st and 2nd of August, the swell drops back to 4 ft to 4 ft, and the period picks up to 12-14 seconds. The wind is offshore on the 2nd morning, which is a nice, clean end to the run. The energy is moderate (590 to 612), so it’s a good, cruisy session for an intermediate surfer.
The best on offer is the morning of the 25th of July. If you can get out then, you’ll have the best mix of good size, a long period, and clean offshore wind. The 27th and 28th are big, but only for the hardcore crew.
Rusty.
