The Lowdown
Alright, folks, Rusty here. Let’s break down what’s happening for Scituate Harbor over the next couple of weeks. I’ll be honest with ya – it’s a tough stretch.
We’ve got a long, dry run starting Wednesday, August 5th, all the way through to Monday, August 17th, with nothing but poor surf. That’s nearly two weeks of flat, small, or just messy conditions. The swell is barely a whisper, with a tiny 0.3ft to 2ft from the southeast or east, and the energy is weak – you’re looking at a combined energy figure of just 3 to 11 for most of that period. It’s a real bummer, and it’s pretty normal for this spot to have such a blank run. The water temp is a bit colder than average for this time of year at 65°F, which is a solid 3°F below normal – not a huge shock, but enough to notice on a flat day.
There are a few mornings where the wind goes offshore or cross-off, like Friday morning, August 7th, with a light westerly, and Sunday morning, August 9th, with a nice NW offshore. But with no swell to work with, it’s just a tease. The wind would be perfect for a clean wave, but there’s nothing to ride.
The only glimmer of hope comes right at the tail end of the forecast. On Monday, August 17th, the afternoon finally shows something surfable, but it’s still very ordinary. The swell bumps up to 3ft from the east-northeast, with a short period of 6 seconds and combined energy of 58 – that’s still weak. The wind is a light northeast cross-offshore, so conditions will be clean. It’s not a standout by any stretch, but it’s the best on offer.
Then Tuesday, August 18th, might be the pick of the entire run. The morning shows a 2ft east swell with a 6-second period and energy of 50. The wind is a solid NW offshore at 12 mph, so it’ll be clean. It’s small, but for a spot that’s been dead for weeks, this is the only real chance to get wet. The break is a reef and point setup, so it can handle a bit of east swell, and the offshore wind will be a major plus. Crowds are possible here, so don’t be surprised if a few other desperate souls show up.
After that, it drops back to tiny again. So, the takeaway? If you’re desperate, keep an eye on the morning of Tuesday, August 18th for a small, clean session. Otherwise, it’s a waiting game. Forecasts can change, but right now, it’s a tough one.
Rusty.
