Sandy Mouth Surf Forecast and Surf Report

Alright, listen up, it's Rusty. Let's break down the next couple of weeks for our local surf.

First thing's first, the start is flat. Real flat. We're looking at a few days of nothing but ankle-biters, so don't be in a rush to wax up. It's a slow burner, but it does get going later.

The first real glimmer of hope is on Wednesday, August 12th. Sandy Mouth starts to show a little pulse. The morning's a washout, but by the afternoon the wind is light and cross-offshore, which will clean things up nicely. The swell is a tiny 0.7m from the west with a 10-second period, and the combined energy is a weak 88. It's surfable, but it's a "get the rust off" session, not a "call in sick" one.

Moving into Thursday, August 13th, the swell picks up a bit to 0.9m from the west, with a longer 11-second period. That longer period means more grunt and better shape. The combined energy hits 185 (moderate), and the morning has light north winds. It's a step up, but still not the main event.

The big talk of the town is the Monday, August 17th to Tuesday, August 18th window. Monday afternoon sees the swell building to 1.2m, but it's accompanied by a fresh 30 km/h cross-onshore wind, making it lumpy. The energy is 226 (moderate to strong). It's a sign of things to come, but not a great session.

Now, Tuesday, August 18th, is the one that gets your blood pumping. The swell jumps to 2.1m in the morning and 2.3m in the afternoon from the west-northwest. The combined energy screams in at 578 to 708 (strong to very strong wave energy). But here's the rub: the wind is a steady 15 km/h cross-onshore. The morning is "fairly choppy," and the afternoon is "poor." It's a classic case of a ton of water moving but messy conditions. For Sandy Mouth, a beach break, this much swell with a short period and onshore wind is going to be a messy, powerful beast. It's strictly for the experts, and even then, it'll be a battle. It's a big, loud, but messy day.

Our best bet for a clean, fun session might actually be the following Thursday, August 20th. The swell has dropped back to a tiny 0.5m to 0.6m from the west, with weak energy. The absolute winner here is the wind: a light 10 km/h offshore breeze from the east-northeast. That means glassy, clean conditions. That little 0.5m wave with an 8-second period will be a dream on a longboard, with the offshore wind holding up the face. It's small, but it'll be perfect.

So, to sum it up: the biggest and most powerful day is Tuesday, August 18th, but it's a messy one for experts only. The best bet for a clean, enjoyable surf is the small, offshore morning of Thursday, August 20th. The rest of the time is a mix of small, weak, or blowy days.

Keep an eye on it, things can change, but that's the picture right now.

Rusty.
