Big Rock Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell coming in for Big Rock, so let’s break it all down.

The first surf kicks off on Monday the 3rd of August. It’s a bit of a mixed bag to start with a 6ft SW swell, but the wind is blowing cross from the NNW at 15 mph, putting a bit of a chop on the surface. The water’s sitting at 67°F which is a touch warmer than normal for this time of year. The wave energy is moderate (1481). It’s surfable, but it’s not the best we’ll see.

Tuesday the 4th sees a big jump in size. Morning brings a clean 12ft WSW swell with offshore winds from the W at 12 mph. That’s a solid combination, but the wave energy is now strong (6692). The afternoon, however, turns ugly with the wind picking up to 15 mph onshore, so you’ll want to be out first thing.

The standout is Wednesday the 5th of August. We’re looking at a 15ft WSW swell with a 16-second period, which is a long-period groundswell. The wind is light from the S at 6 mph in the morning, creating only a light cross-shore ripple. Wave energy is very strong (10754). This is big, powerful, and clean. It’s a serious swell, over 8ft, so this is for experienced surfers only. The long period will make it punchy, and at a reef break like Big Rock, it’s going to line up nicely. The afternoon is still good with a light cross-onshore breeze. This is the best on offer.

Thursday the 6th is a write-off. Strong cross-onshore winds and a 13ft swell make for messy, choppy conditions. Same story for Friday the 7th – the morning is marginal, but the afternoon brings a 25 mph cross-onshore gale with 13ft swell. Not worth it.

The weekend gets wild. Saturday the 8th has a massive 18ft SW swell, but it’s blown out by a 19 mph cross-onshore wind. The wave energy is enormous (14668), but it’s too big and messy for paddle surfing. This setup looks more interesting for kite surfing. The afternoon is slightly better wind-wise, but still too big.

Sunday the 9th drops back to 13ft SW with offshore winds, which is a decent call, but the wind is moderate. Not a standout, but a solid option.

The following week starts rough. Monday the 10th and Tuesday the 11th are hammered by strong to gale-force winds, with 18ft SW swell on Tuesday. The energy is huge (14719), but the wind is howling. Again, this is kite territory.

Wednesday the 12th looks better. A 18ft SW swell with 16-second period, and the wind is moderate cross-shore. Wave energy is very strong (14709). It’s big and powerful, but cleaner than the days before. Still for experts only.

Thursday the 13th and Friday the 14th are smaller. Friday morning the 14th is a little gem: 6ft SW swell with glassy conditions from the ENE at 3 mph. The wave energy is moderate (2004). This will be clean and fun, but it’s a smaller swell.

Saturday the 15th of August is another promising one. A 10ft SW swell with glassy conditions in the morning and a 16-second period. Wave energy is strong (4085). This is a standout for surfers who can handle the size. The glassy conditions will make it perfect.

The run continues into the 16th and 17th with 8ft WSW swells and clean cross-offshore winds from the NNE. Consistent, clean, and a good size for intermediate to advanced surfers.

The last day on the 18th of August has a 10ft WSW swell, but the wind picks up to a fresh cross-shore, making it lumpy. It’s a fade-out.

So, the clear standout is Wednesday the 5th of August – big, powerful, long-period groundswell with light winds. Second best is Saturday the 15th of August for the glassy morning session on a solid 10ft swell. Get out there for those.

Rusty.
