The Lowdown
Alright surfers, Rusty here. Let’s have a look at what’s in store for Balneario Sao Jose.
It’s a pretty quiet start to this forecast window, with not much to get excited about for the first few days. The surf that’s around is small and weak, and the conditions aren't playing ball. We’ll be waiting a bit for things to turn on.
The real action kicks off on Friday morning, 24 July. The swell picks up to a clean-looking 5 ft from the S, and the wind goes dead glassy with a NE breeze at just 3 mph. The wave energy hits a moderate 356, and the forecast is calling for good surf. This is your window. The afternoon stays just as good, with the swell shifting to SSE at 5 ft, a 10-second period, and a flat calm WNW wind. This is the standout of the whole outlook – clean, punchy waves, and the place will be all yours for a proper session.
Saturday 25 July holds onto that quality. Morning glass-off with N wind at 3 mph and 4 ft from the SSE. The energy is still solid at 299. Afternoon goes glassy again with a ESE breeze at 0 mph. Two days of back-to-back clean surf is a treat.
Sunday 26 July starts with a glassy morning, but the swell drops to 2 ft from the S. The period is a very long 14 seconds, which will give the waves some shape but expect longer lulls between sets. The afternoon gets a bit messy with a cross-onshore wind.
From Monday 27 July onward, the swell drops off into the mediocre range. There are a few glimmers, like the Monday morning glass-off with 3 ft from the SE, but the energy is low at 177. The rest of the week is a mix of small, cross-onshore slop and poor conditions.
Looking further out, Monday 3 August morning shows a glimmer of hope with a 3 ft S swell, glassy conditions, and a 219 energy reading. Tuesday 4 August morning also looks promising with a 3 ft SSE swell, glassy NW wind, and a solid 262 energy value. These are far out though, so keep an eye on them but don’t lock in plans yet.
Water temp is sitting at 67°F with no anomaly, so it’s pretty average for this time of year – a bit cool but fine with a spring suit.
This is a beach/pier break, and it’s fairly consistent. Crowds can be a factor here, especially when the surf is good, so get out early on that Friday morning.
Signing off,
Rusty
