Thurso Beach Surf Forecast and Surf Report

Right, grab a coffee, this is a long one. First up, let’s be straight: for a place called Thurso Beach, this is a rough start. For the next few days, it’s mostly a write-off—strong, nasty winds and messy, blown-out surf. But if you’re patient, there are a couple of windows where it cleans right up, and some serious swell on the horizon that, if the wind plays ball, could be the session of the month.

The immediate outlook is grim. Saturday the 5th is a no-go: 25 mph cross-shore wind tearing up a messy 12 ft cross-chop. That’s a hard pass. Sunday the 6th and Monday the 7th see the size drop right back to under 4 ft, but the wind goes offshore. The problem is the swell energy is weak, with readings around 118 to 166, and the period is short, so the waves will be small, weak, and lacking any punch. It’s clean but barely surfable.

Tuesday the 8th is a beast, but not a friendly one. We get a big W swell piling in—12 ft in the morning, 10 ft in the afternoon—with combined energy rocketing up to 4199. That’s a serious amount of power, but the wind is a howling 31 mph near-gale. It’ll be a washing machine. Not for us. Wednesday the 9th is still lumpy and cross-shore.

The first real standout isn’t until Monday the 14th and Tuesday the 15th. Monday afternoon sees a clean 8 ft W swell at 8 seconds with a moderate cross-off breeze. The energy is moderate, around 943. It’s not perfect, but after days of slop, that clean face will feel like a gift.

But the real jewel in this forecast is Tuesday morning, September 15th. This is the one to circle. We’ve got a solid 12 ft WNW groundswell with a moderate offshore wind from the SW. The combined energy is a chunky 2323, and it’s clean. The only caveat is the break itself: Thurso Beach is a fairly exposed beach break, and a long-period swell like this (10 seconds is decent) can sometimes break a bit straight on the sand. But with clean offshore texture and that size, there will be some proper wedges. It’s potentially too big for beginners, but for the rest of you, this is the call.

After that, the swell stays solid through the 16th and 17th, with a 13 ft WNW groundswell on Thursday the 17th showing insane energy readings of 4283. Again, it’s clean, but that size at a beach break is strictly for experts. The cross-off wind will keep it from closing out completely, but you’ll need your wits about you.

Into the final weekend, things drop back down. Friday the 18th morning has a nice 5 ft WNW swell with a light SSE offshore. The energy is 502, which is a healthy moderate level for a clean, fun-sized wave. It’s the perfect finisher—much smaller, but much more user-friendly.

So to sum it up: the first week is a battle against the wind. The winner is Tuesday the 15th morning for big, clean swell. The runner-up is Monday the 14th afternoon for a solid clean session, and Friday the 18th morning for a smaller, cleaner day if you just want some cruisey turns. The water temperature is about average for the time of year.
