The Lowdown
Right, the only surf option on the table for the next 16 days is Balneario Sao Jose, and honestly, it’s a bit of a mixed bag. You’ve got an exposed beach/pier set-up that’s fairly consistent, and it likes swell from the SE. The water temp feels about average for this time of year, nothing weird going on there.
The best of the lot looks like Thursday 10th. Thursday morning, the swell bumps up to a solid 7ft from the east with a short period of 8 seconds, and the energy’s pumping hard (1051). The wind is glassy, absolute zero, so it’ll be clean as a whistle. That wave energy is strong, but that size and period will make it a bit of a handful – definitely one for the experienced crew only. More manageable but still a good call is Thursday afternoon, with a 6ft east-southeast swell, 9 seconds of period, and a cross-off breeze keeping things tidy.
Before that, the weekend and start of the week are a write-off with onshore winds and rain. Thursday 3rd and Friday 4th have some small windows – Thursday morning had a clean 5ft SSE swell (610), but that’s already in the past. Friday morning looks glassy with a small 3ft SSE swell (287), nice and clean for a longboard or a fish.
Looking further out, there’s a nice little window on Wednesday 9th: both morning and afternoon are glassy. The morning has a weak 3ft SSE swell (356), while the afternoon pumps up a bit to 5ft from the east-southeast with a short period, still glassy (331). That afternoon would be a fun, easy session.
Monday 14th has a weird one – a 2ft swell from the south with a very long 13 second period (451) and a cross-off wind. That long period at a beach break might make it a bit straight, but it’ll be clean.
Honestly, the standout is Thursday 10th for the size and conditions, but it’s for the confident surfer. For the everyman, Wednesday 9th afternoon is the pick for a stress-free glassy wave.
