The Lowdown
Hey, Rusty here. Looks like we’ve got a solid run of surf coming down the pike, but it’s gonna build from small and clean to some real heavy stuff. Let’s break it down.
Black Rocks Jetty (reef) is the only spot in the game. Water temp is sitting at 25°, which is a touch warmer than usual for this time of year – a nice little bonus.
Kicks off Monday morning, August 3rd. Glassy, dead calm, with a 1.2m SW swell at 14 seconds. The combined energy is strong (965). That’s a very good session. Monday afternoon holds up too, glassy again with 1.1m SW swell at 13 seconds (701 energy). Still very good.
Tuesday the 4th drops off. Morning has 0.7m SW swell, glassy, moderate energy (289). Afternoon is similar with a 0.7m S swell. Clean, but small.
Wednesday the 5th is a mixed bag. Morning is glassy, 0.7m SW swell, but the period jumps to 15 seconds – that’s long-period groundswell, energy at 329. Afternoon gets onshore wind, so morning is the call.
Thursday the 6th has cross-onshore wind in the morning, making it marginal. Afternoon cleans up – glassy, 0.9m SW swell at 13 seconds (271 energy). Good small waves.
Friday the 7th is glassy again in the morning, 0.8m SW swell at 12 seconds (250 energy). Then Friday afternoon throws a weird one – tiny 0.5m swell, but with a 22-second period. That’s a very long-period groundswell, energy jumps to 472. At a reef, those long lines will wrap in, but you’ll be waiting between sets.
Saturday the 8th of August is the standout of the first week. Morning is glassy, calm, 1.2m SW swell, 18-second period, strong energy (1008). That’s excellent for experienced surfers. Afternoon stays glassy with 1.4m SW swell, still very good.
Sunday the 9th gets messy with onshore wind. Monday the 10th and Tuesday the 11th have clean cross-offshore winds in the mornings, 1.3m and 1.5m SW swells – very good, but the afternoons get onshore.
Wednesday the 12th of August is another standout. Morning is glassy, calm, 1.6m SW swell at 14 seconds, strong energy (1063). Excellent for experienced surfers. Afternoon is glassy with 1.4m, still very good.
Thursday the 13th jumps to 2.2m, but cross-shore wind makes it bumpy – expert territory. Friday the 14th is better – morning glassy, 1.7m SSW swell at 13 seconds, energy at 1380. Excellent for experienced surfers.
Sunday the 16th of August is a cracker. Morning glassy, 1.8m SW swell, 18-second period, energy at 1925. Afternoon glassy, 1.5m at 18 seconds. Excellent for experienced surfers.
Monday the 17th of August is the biggest – 2.2m SW swell, dead calm, 16-second period, energy at 2413. That’s strong to very strong. Excellent for experts only. Afternoon gets onshore.
Tuesday the 18th of August – morning glassy, 2.4m SSW swell, 15-second period, energy at 2594. Afternoon glassy, 2.2m SW swell. Both are excellent for experienced surfers only.
This spot is very consistent, so there’s always something to ride. Crowds are possible. If you’re a beginner, keep it to the days under 1.5m. Over 2.5m, it’s for the experts.
Rusty.
