Guarita Surf Forecast and Surf Report

G’day, it’s Rusty here. Let’s have a look at what’s coming up at Guarita (reef, expert-level).

The next 16 days start quiet, but there’s a proper pulse of energy later on. For a reef setup like this, you wanna keep an eye on the swell direction – this spot works best with easterly swell.

Right now, Friday the 4th of September, there’s tiny 2 ft swell from the SE with a 10-second period. Very weak energy (99) and glassy wind from the SE at 3 mph. The water is 62°F, which is pretty average for this time of year – nothing unusual there. It’s surfable but tiny; not really worth paddling out for.

Saturday the 5th is lackluster. Morning shows 3 ft from the S, 9-second period, cross wind (SSW 6 mph). That’s a light cross-shore with small ripples, and the energy creeps up to moderate levels (227). Afternoon brings 4 ft from the S, still short period (8 sec), and a gentle cross-shore producing some chop. Both sessions are marginal at best.

Sunday the 6th sees a jump. Morning pushes 8 ft from the S, 8-second period, with a cross-offshore wind (SW 16 mph). The combined energy is strong at 1386. This is getting big and powerful, but the short period and size – over 8 ft – mean this is strictly for experienced surfers only. The wind keeps it clean, though. Afternoon drops to 7 ft from the S (10 sec, 727 energy) with a fresh cross-offshore breeze. Still clean, but again, big and demanding.

Monday the 7th morning is the first true standout. Swell drops to a more manageable 5 ft from the SSE, 9-second period, with glassy conditions (N wind 3 mph). Combined energy is moderate (297). This is clean, glassy, and the size is perfect for experienced surfers – good shape on a reef like Guarita. The afternoon turns onshore (E 9 mph) and turns choppy, so that morning window is the one.

Tuesday the 8th through Wednesday the 9th are messy. Swell stays around 3 ft to 4 ft, but cross and onshore winds ruin it. Choppy and poor.

Thursday the 10th offers 2 ft from the S with a very long 16-second period in the morning, dropping to 14 seconds in the afternoon. That’s a long period groundswell, but the size is tiny and it’s onshore wind. Not happening.

Friday the 11th builds back to 5 ft from the E (7 sec) in the morning, then 6 ft from the E (7 sec) in the afternoon. Short period, cross wind, poor conditions. Not recommended.

Saturday the 12th is wind-blasted in the morning with 25 mph SW cross-offshore wind and only 4 ft from the E – that’s a kitesurfing setup. Afternoon improves: 8 ft from the S, 10-second period, clean cross-offshore wind, strong energy (1163). Big and clean, but only for experts.

Sunday the 13th morning bumps to 8 ft from the SE, 11-second period, clean cross-offshore wind (WSW 9 mph). Very strong energy (1526). Excellent for experts. Afternoon goes cross-shore with 16 mph wind and a chop, so morning is the call.

Monday the 14th is the true standout of the whole forecast. Morning delivers 7 ft from the ESE at 12 seconds – that’s a long period groundswell, well-directed for Guarita – with glassy wind (N 3 mph). The energy is strong (1370), and conditions are described as excellent for experienced surfers. This is the session to circle on your calendar. Afternoon turns onshore and drops off, so don’t sleep in.

Tuesday the 15th and Wednesday the 16th fade to small, poor, or marginal. Wednesday morning the 16th has 3 ft from the ESE (11 sec) with glassy wind and good conditions, but it’s small.

Thursday the 17th offers clean, small surf: 3 ft from the ESE (10 sec) with cross-offshore wind (SW 6–9 mph). Good for a longboard or a small-wave craft.

Friday the 18th sees a late push: 4 ft from the S at 12 seconds in the morning, strong energy (1010), clean cross-offshore wind. Afternoon turns cross-shore with chop. A decent option for the more experienced.

Saturday the 19th closes the window with 3 ft–5 ft, cross and onshore winds, poor for the most part.

If I had to pick the real standouts: Monday the 7th morning – glassy, 5 ft SSE, clean – and Monday the 14th morning – 7 ft ESE, glassy, long period, excellent for experts. That second one is the best on offer.

Rusty.
