The Lowdown
Alright, Rusty here, giving you the rundown on what’s cookin’.
First off, we’ve got a slow start, so don’t paddle out just yet. The first real chance to catch a wave is on Monday morning, July 20th, at Little Austi and Main Beach (a beach and reef setup). The water temp is about 64.6°, which is normal for this time of year, nothing to write home about.
Monday morning is the pick of the first week. You’ve got a clean 6.2ft ENE swell with an 11-second period. The wind is light and offshore from the NW, leaving the surface glassy. The combined energy is moderate (863). It’s not huge, but it’s clean and fun for an intermediate. Expect a few heads out, as it can get crowded here sometimes.
The rest of that week goes flat quick. Tuesday morning still has a clean 4.6ft, but the energy is lower (402). By Wednesday afternoon, the swell is down to 3.3ft, and by Thursday, it’s only 2.3ft with a moderate cross-off breeze. From Friday through the end of the month, we’re in a proper dry spell, with nothing but tiny waves and poor conditions for days. A long gap of no real surf.
Saturday, July 30th is where things start to pick up again. A new swell fills in from the SSE, which is the right direction for this spot. Saturday morning shows a clean 5.2ft swell with an 11-second period and a light cross-off breeze. The energy is moderate (564). This is a solid run.
Monday, August 3rd is the real standout, and it’s a big one. This is over a week out, so keep an eye on it, but it looks promising. We’re looking at a solid 9.8ft SSE groundswell with a very long 13-second period. The combined energy is strong at 2954. That’s a lot of power. The wind is light and cross-off from the WSW. This is going to be a powerful, clean wave, but it’s for experts only at that size. It’s a point break and reef setup, so that long-period swell will line up nicely, but it might be too much for the beach breaks. This is the best on offer.
Short Range ForecastMostly dry. Very mild (max 17°C on Mon morning, min 10°C on Sun night). Wind will be generally light. | Days 4-6 Weather SummaryMostly dry. Warm (max 21°C on Wed morning, min 7°C on Thu night). Wind will be generally light. | ||||||||||||||||||||
