Las Gramas Surf Forecast and Surf Report

G’day, Rusty here, your local surf reporter. Let’s get into it. We’ve got a 16-day window for Las Gramas, a sandbar set-up that’s very consistent and exposed to the SW. It’s an intermediate spot, but don’t get too excited just yet—the first week is a bit of a grind with marginal conditions.

The water temp is about average for this time of year, so nothing out of the ordinary there.

The pattern starts off pretty flat and messy. Friday, 31 July, there’s a small SW swell around 3ft with a 12-second period, but the cross-off wind from the south at 12-12 mph keeps it cleanish. The combined swell energy is weak (349) and the score is low—it’s a “marginal” call, not worth paddling for.

Saturday, 1 August, the swell picks up a bit to 5ft from the S, but the period drops to 8 seconds. That’s a short-period windswell, and with cross-shore winds from the SSW at 6-9 mph, it’s going to be choppy. The energy is moderate (532), but the quality is poor.

Sunday, 2 August, through to Tuesday, 5 August, is a stretch of weak SW swells, 2ft to 4ft, with periods between 7 and 13 seconds. Winds are light and cross-shore most days, but the surf is barely there. It’s a real lull. The energy stays low (284 to 720), and the ratings are all “marginal” or “poor.” No good waves on offer.

Now, the first standout is Thursday, 6 August. The morning sees a tiny 3ft SW swell, but check the period—18 seconds! That’s a very long-period groundswell. The wind is almost glassy from the SW at 3 mph, and the energy is moderate (928). The afternoon is when it gets good: cross-off wind from the SSW at 9 mph, clean conditions, and the swell holds at 3ft with a 16-second period. The energy is solid (813). This is the best session of the first week.

Friday, 7 August, is another highlight. The morning delivers 5ft SW swell with a 15-second period, light cross-off wind from the S at 6 mph, and clean conditions. The energy is strong (969). This is a proper swell—long period, clean, and the right direction. The afternoon gets a bit messy with cross-shore wind, but the morning is the pick.

Saturday, 8 August, has a similar setup: 4ft SW swell, 13-second period, light cross-off wind from the S in the morning, clean. Energy is moderate (639). Another good session.

There’s a gap from Sunday, 9 August, to Monday, 10 August, with only marginal surf or poor conditions. Tuesday, 11 August, brings a small S swell at 5ft with an 8-second period, but the energy is strong (1117). Still, it’s short-period and cross-shore wind, so not great.

The second week, from 12 August onward, sees a building trend. Wednesday, 12 August, has a 6ft S swell with a 9-second period, light cross-shore wind, and strong energy (968). Thursday, 13 August, bumps up to 7ft S swell, 10-second period, with cross-shore wind from the SSW at 9 mph. The energy is very strong (1294). This is getting big—over 7ft, so it’s expert territory. The period is short, so it’ll be a bumpy, powerful beach break, not ideal for the average surfer.

Friday, 14 August, holds at 6ft to 6ft, S swell, 10-second period, with light cross-shore wind. Energy is strong (1062 to 1102). Still marginal for quality.

The absolute standout of the entire forecast is Saturday, 15 August. The morning delivers 5ft S swell with a 10-second period, light cross-off wind from the S at 6 mph, and clean conditions. The combined energy is very strong (1070). It’s the only session rated “excellent” for experienced surfers. The wind is offshore, the swell is solid, and the energy is pumping. This is the one to circle on the calendar. Crowds are often an issue at Las Gramas, so with the good conditions, expect company.

Overall, the first week is a write-off except for the 6th and 7th, then the second week builds to a real gem on the 15th. Keep an eye on that one.

Rusty.
