Alright, Rusty here, let’s talk about the stretch ahead. We’ve got a bit of a slow start, but don’t walk away just yet – there’s some fun stuff lining up, especially if you’ve got a little patience.
Right now, the first few days are pretty average. Sunday morning, the 5th of July, is kicking off with a 5.2ft south swell at 12 seconds, but the wind is cross-on from the south at 3 mph, so it’s a bit messy. The water’s sitting at 68.7°, which is pretty much normal for this time of year, so nothing to get excited about there. The combined energy is moderate (700), but the conditions are just marginal. Monday morning, the 6th, actually looks glassy with a calm wind, but the swell has dropped to 3.9ft from the south, and the energy is down to 461. It’s clean, but small. That’s about as good as it gets for the first week, honestly. There’s a gap of a few days with nothing really worth paddling out for.
Then we hit a real highlight. The morning of Sunday, the 12th of July, is where it’s at. We’ve got a 3.9ft south swell with a 13-second period, and the wind is blowing cross-off from the northwest at 3 mph. That’s clean, glassy conditions, and the combined energy jumps up to 694. This is the best on offer for the whole window. Balneario Sao Jose is a beach/pier setup, and with that long-period groundswell, the waves will have some real shape and energy. It’s a fairly consistent spot, but crowds can be a thing here, so get in early. The afternoon holds a similar vibe with an offshore wind from the north-northwest.
After that, things taper off again. The second week is pretty quiet, with tiny swells and onshore winds for most of it. But keep an eye on the morning of Saturday, the 18th of July – a 5.2ft south swell with a short 7-second period pops up, and it’s glassy. It’s a bit jumbled from the short period, but if you’re desperate for a wave, it’s there. The morning of Sunday, the 19th, also looks clean with a 3.3ft south swell and offshore tendencies.
For the long-range stuff, the 20th of July shows a 4.6ft south-southeast swell with a very long 15-second period, and the combined energy is strong at 956. That’s serious groundswell energy, but it’s a bit of a gamble this far out, and the wind is cross-shore, so don’t book your flights yet.
Overall, if you’ve got one day to make it count, make it Sunday the 12th of July. That’s the standout.
