The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got at the Siletz River mouth at Taft.
First thing you'll notice: the water is a chilly 53°F – that's a whopping 6°F colder than the average for this time of year. You're definitely gonna want a thick, hooded wetsuit and maybe some booties. The issue is this is a river mouth, so it really needs clean conditions to be any good. For the next couple weeks, we've got mostly cross-onshore breezes and choppy, messy surf.
The combined swell energy is mostly in the weak to moderate range. Thursday, August 20th, shows a bit of a bump with the energy hitting moderate and we see a clean 4ft swell from the WNW with an 11-second period. The wind is light in the morning, but it's still cross-onshore. It's surfable, but not that perfect glass.
Friday the 21st has a tiny 2ft from the SSW with a longer period, but the swell's just too small. Saturday the 22nd the wind kicks in and it gets choppy again. Honestly, from the 22nd until the 28th it’s pretty bleak. Mostly poor to marginal surf forecasts, with messy winds and short-period junk.
The one genuinely good moment is Saturday, August 29th. The afternoon is forecast to be glassy – that's a huge deal for a river mouth. The swell is only a small 2ft from the SW with a 14-second period, and the energy is weak. But with glassy conditions and that long-period groundswell wrapping in, it could be a fun little session. It won't be big, but it'll be clean.
So, if you're hanging on for a wave, the best bet by far is that glassy window on the afternoon of August 29th. The rest is pretty quiet.
Rusty.
