Alright folks, Rusty here. Let’s have a look at what’s shaping up for Laguna (Os Molhes) over the next couple of weeks.

The first few days are a bit of a write-off, but hang in there. We’ve got a slow start with poor conditions on Thursday the 9th; the wind is all over the place and the waves are small and messy. You’ll be better off waiting. The real action starts to kick off on Friday morning, July 10th. That’s when we finally see some clean conditions with a light offshore wind from the SW. The swell is a tidy 3 ft from the ESE, with a period of 12 seconds – that’s got some decent energy behind it (combined energy of 259). It’s not huge, but it’ll be clean and lined up. If you’re keen, Friday morning is your first real look.

The standout of the whole run, though, is going to be Saturday morning, July 11th. This is the one. We’re looking at glassy conditions, absolutely no wind, and a clean 4 ft swell from the ESE with a 13-second period. The combined energy is pumping at 536, which is a solid moderate energy. The water temp is about average for this time of year – nothing unusual, just your standard winter water. This is a proper morning session; the waves will have shape, power, and that glassy surface is a dream. Get out there early.

Sunday the 12th keeps the good run going, with a morning offshore WSW wind and a 5 ft swell from the SSE, period at 11 seconds. That’s clean and punchy, with combined energy of 837 – that’s a solid push of water. The wind stays favourable through Sunday afternoon too, so you’ve got a full day of options.

Into the next week, things get a bit more mixed. Monday the 13th still has clean offshore wind, but the swell drops back to 3 ft. Tuesday the 14th morning is clean with a cross-offshore breeze and 4 ft swell, but the afternoon turns onshore and messy. Wednesday the 15th and Thursday the 16th are mostly poor – onshore winds and choppy conditions. Not worth paddling out.

Now, there’s a promising little window on Friday the 17th. The morning has a light cross-offshore breeze and 5 ft swell from the ENE, but the period is short at 8 seconds. The afternoon goes glassy, with a 4 ft swell and no wind. It’s not the best quality swell, but it’ll be clean and rideable. Saturday the 18th is messy again.

Looking further ahead, Sunday the 19th morning is glassy with a 4 ft NE swell, but again, short period (8 seconds). The real long-range hope is Monday the 21st and Tuesday the 22nd. Monday the 21st has glassy conditions in the morning with a 5 ft NE swell, and Tuesday the 22nd morning has a gentle offshore SW breeze with the same 5 ft NE swell. That’s the biggest swell of the forecast, and with clean wind, it’ll be a good option for experienced surfers. The combined energy is around 477 – solid moderate. Keep an eye on that one, but remember it’s a week and a half away, so things can change.

After that, the last few days of the outlook look pretty poor again with strong onshore winds and small, messy surf. So, your best bets are Saturday morning July 11th for the glassy, dreamy conditions, and then the Monday/Tuesday of July 21-22 for the bigger, cleaner swell. Don’t waste your energy on the flat days.

Stay stoked,
Rusty
