Guarita Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down the next few weeks at Guarita. It’s a reef break, so we need the right direction and some juice to make it work. Overall, there’s a few moments, but plenty of quiet time too.

We start slow. Wednesday and Thursday mornings, September 9th and 10th, have tiny swell—around 3ft to 3ft from the SSE, short periods, and weak energy (325 to 410). Winds are cross or cross-on. Nothing to get out of bed for. Water temp is just average for the season here.

First flicker of hope comes Friday morning, September 11th. Swell jumps to 5ft from the ENE, short period (8 seconds), but the wind is cross-offshore out of the north at 6 mph, keeping it clean. Energy is moderate (350). It’s a small, clean wave, not a standout, but a step up.

Now, the big moment. Saturday morning, September 12th. Swell hits 8ft from the SSE, period 10 seconds, and the energy jumps to a strong 1057. Wind is cross-offshore from the southwest at 12 mph, and the report says clean. That’s a serious session for experienced surfers—8ft on a reef is no joke. This is your window.

Sunday, September 13th stays big—6ft from the SE in the morning, energy high at 1292, but the wind turns onshore (ESE at 6 mph) and it gets messy. Afternoon is no better.

The following week gets patchy. Monday, September 14th morning is clean with cross-offshore wind and 3ft from the SSE (period 11 seconds, energy 464), but it’s small. After that, Tuesday the 15th through Wednesday the 16th is mostly small (3ft to 4ft), weak energy (268 to 392), and bad wind. Not good.

Thursday, September 17th morning gives 5ft from the SSE, period 13 seconds (long period), energy 864, with cross-shore winds at 9 mph. It’s a decent option, but not a standout. Afternoon is a mess: 18 mph cross-on wind, lumpy.

Friday, September 18th morning is glassy with 3ft from the SSE, period 11 seconds, energy 301. Small, but glassy—great for a fun little session.

From Saturday the 19th, it drops off hard. 2ft, 1ft, energy down to 85. Almost flat. The final week (September 20th to 24th) shows a few pulses of 4ft to 5ft, but all with short periods (6-8 seconds), poor wind (cross-on or onshore), and energy under 500. Bad quality. Kite surfers might enjoy the bumpy windswell more than paddle surfers.

The only true standout is Saturday morning, September 12th. That’s your day. The rest is small, short-period, or wind-affected. There’s a gap of a few days around the 19th-20th where it’s basically flat. Guarita is usually fairly consistent, so this lean stretch is a bit of a bummer.
