Big Rock Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Big Rock.

This is a tricky stretch ahead for the next couple of weeks. We’re looking at a lot of days where the wind is just working against us, but there are a couple of windows that could be worth paddling out for. The first real shot of the period is a very special one, but then it gets quiet and messy until the back half of the outlook.

The best surf on offer is going to be Wednesday, September 9th. That morning and afternoon, Big Rock is looking like a totally different spot. The swell is a tiny 2ft to 2ft from the SW, but that’s a long-period groundswell at 16 seconds, carrying moderate wave energy (399-416). The key here is the wind: it’s glassy. Absolutely clean, no wind at all. That’s a major positive. The water is sitting at 22°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit. For a spot that’s a reef break and exposed to the W, that kind of calm, glassy condition on a long-period SW swell is a rare treat. Keep your expectations in check on the size, but the quality could be real special. It’s a short window, but it’s the highlight of the entire forecast.

Leading up to that, the weekend and early next week are a write-off. Sunday the 6th kicks off with a 6ft SSW swell but the wind is a 19 mph cross-shore, making a mess of things. The wave energy is very strong (1569), but the wind just ruins it. Monday and Tuesday are similar stories with cross-onshore winds and choppy, poor conditions. Honestly, save your energy for Wednesday.

After that glassy Wednesday, things go downhill again. Thursday the 10th through to the weekend of the 13th-14th is a lot of small, short-period windswell with poor or marginal conditions. The wind stays onshore or cross-shore, and the swell drops below 3ft. Not worth your time.

Now, looking further ahead into the second week, there’s a glimmer of hope around September 18th and 19th. The swell is still tiny (2ft to 3ft), but the period is very long again, pushing 18-19 seconds from the SW. The wave energy is moderate (500-533). The wind is forecast to be light onshore or cross-onshore, which isn’t ideal, but if you’re desperate, the long period might offer some clean lines at this reef. This is a long-range call, so it’s promising but less certain. Don’t get your hopes up too high, but keep an eye on it.

Overall, the first half of September is a test of patience. Wednesday the 9th is the standout. Everything else is a battle with the wind. For a spot like Big Rock that’s fairly consistent, this feels like a prolonged flat spell dictated by bad wind. If the wind swings, the conditions could turn around quickly, but as it stands, pick your moment carefully.

Rusty.
