Table - best surf conditions forecast for Balneario Sao Jose over the next 16 days.
Alright, Rusty here, talking in feet and degrees now for the imperial crew.
The week ahead starts quiet. First chance to paddle out is Wednesday morning, July 8th, at Balneario Sao Jose. We’re looking at small 3ft surf from the southeast, glassy with a light NNW breeze. Water temp is about 68°, which is right where it should be for this time of year – no surprises.
Thursday, July 9th, stays small with 3ft from the south, glassy again. Just a nice little warm-up.
The real standout of the first week is Saturday morning, July 11th. We get a clean jump to about 4ft from the southeast, with a solid 13-second period – that’s real groundswell energy. The combined energy reads 454, a solid moderate-to-strong push. Wind is dead calm, so expect glassy, clean walls. Swell direction is dead on for this break, and that longer period will mean longer waits between sets, but cleaner, better-shaped waves. That’s your best bet for the first half.
Sunday, July 12th, keeps that energy high at 460, but the waves are smaller, around 3ft. Glassy again in the morning.
Tuesday, July 14th, starts showing some muscle with 5ft from the SSE in the morning, glassy. By the afternoon it’s holding at 5ft, still glassy. The period is shorter though, around 9 seconds, so it’s more of a wind swell feel – fun but not as refined.
Jumping into the second week, Monday morning, July 20th, is a clear highlight. We’ve got 5ft from the east, period at 8 seconds, but it’s blowing clean offshore from the north. The energy is strong at 463. That’s the biggest, cleanest swell of the whole run. Tuesday, July 21st, follows up with 5ft from the ESE with offshore north winds again – another great session.
After that, size fades, dropping to around 4ft by Thursday, July 23rd. Still clean, but smaller.
The two must-hit sessions: Saturday morning, July 11th for the clean groundswell, and Monday morning, July 20th for the biggest, cleanest waves of the period.
Rusty.
