The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Trez Hir. It's a spot that doesn't fire all that often, so when it does, you've gotta be on it.
The first bit of the outlook is pretty slim pickings. From now through the end of August, there's small, weak swell and the wind is either cross or messy, keeping the quality low. It's a quiet start.
Monday the 31st of August, though, is where things get interesting. The morning session is the real standout. We've got a solid 8ft swell rolling in from the west with a 10-second period, combined energy of 1370, which is a proper push. The wind is blowing offshore from the WNW at 12 mph, keeping the face clean and lined up. The forecast says it's excellent for experienced surfers, and at that size, it's no place for beginners. With the break being rare, to get it this good is a real treat.
The energy drops off for the early part of September, with nothing worth paddling out for until the morning of Saturday the 5th of September. That's the other big highlight. We get another 8ft west swell, this time with a longer 12-second period (1953 in the energy department), and the wind goes glassy from the NNW at 3 mph. Expect clean, powerful lines. Again, this is expert territory. The long period means the sets will hold up well on the reef, but can be a bit tricky on the shorebreak. It's a short window of glory before the wind and swell turn a bit lumpy again on Sunday.
So, to put it simply: the two mornings to circle are Monday the 31st of August and Saturday the 5th of September. That's your very best bet for a clean, strong swell with the right wind. For the rest of the 16-day window, there are small, average, or just messy days, although the occasional 7ft+ wave might show up with a cross-off wind. But honestly, the standouts are those two mornings.
Rusty.
