The Lowdown
Alright folks, Rusty here with a look at the upcoming swell window. Straight up, this is a tough one to call. The 16-day forecast for Portreath Beach is mostly a story of waiting for a break in the weather, but there are a couple of moments that are worth getting the wax out for.
For the first week, from now through the 3rd of September, it’s a write-off. We’ve got a constant stream of strong cross-shore and onshore winds ruining whatever swell there is. The water temp is running about average for this time of year, so no surprises there, but the quality is just shocking. On Saturday the 29th, there’s a massive boost in energy with a combined swell energy reading of (1615) and waves pushing 10ft from the WSW, but it’s being hammered by a strong cross-shore breeze that’s making it a messy, lumpy mess. That setup is more interesting for kite surfing than paddle surfing. After that, the wind stays cranky and the waves are just poor.
Now, here’s the glimmer. We finally get a break in the action on the morning of Friday the 4th of September. The wind drops to nothing – total glassy conditions, calm as can be. We’re looking at a clean 5ft W swell with a 10-second period. That’s a bit of a long period for a beach break, so it might be a touch straight, but when it’s that clean you take what you can get. The combined swell energy is a moderate (476). It’s not huge, but it’s the standout of the entire period. This is your window.
Don’t get too excited for the weekend after that, as the wind swings back onshore and it gets lumpy again.
Then, looking way out, there’s a promising but less certain call for Monday the 7th of September. The forecast has a very solid 12ft W swell rolling through with a 10-second period and clean cross-offshore winds from the SW in the morning. The combined energy is pumping at (2318). However, that’s big surf – over 8ft – so it’s strictly for experienced surfers who know Portreath well. It might also be too big for the break to handle properly. Keep an eye on it, but don’t hold your breath.
So, to sum it up: the best bet by far is the glassy, clean 5ft swell on the morning of Friday the 4th. The rest is a waiting game with a big, expert-only possibility on the 7th.
Rusty.
