The Lowdown
G’day, Rusty here, and I’ve got to be straight with you—this next stretch at Foz do Lizandro is a tough one. The whole 16-day window is a bit of a write-off, if I’m honest. There’s no standout surf on offer, no day where the stars align. The wind is almost always cross or cross-onshore, and the swell is small and weak. Let’s walk through it.
We start off on Saturday, 1st August, and it’s already a no-go. The swell is a tiny 2ft from the west, with a period of 9 seconds, but the wind is a moderate 16 mph from the north, blowing cross-shore. The combined energy is weak at 139, and the water comment says “poor surf conditions.” The breeze is a moderate cross-shore with a cross-chop. That’s not going to clean up. The water temp is about average for the time of year, nothing unusual to report.
Sunday, 2nd August, is more of the same—2ft swell, cross-onshore wind, weak energy. It’s a flat, choppy mess. Monday, 3rd August, sees a slight bump in the afternoon to 4ft, but the period drops to 8 seconds and the wind is still cross-onshore from the southwest at 12 mph. The combined energy hits 177 (moderate), but the texture is poor. Tuesday, 4th August, has a morning window with a light breeze from the west-northwest at 6 mph, cross-onshore, and a 3ft swell from the west-northwest with a 9-second period. Energy is 132 (moderate), but it’s still “poor surf conditions.” The wind is just light enough to keep it from being a total mess, but the cross-onshore angle is still there.
Wednesday, 5th August, through to Friday, 7th August, is a dead zone. Swell drops to 2ft to 3ft, wind picks up to 19 mph at times, and the energy is weak. The water is getting lumpy with cross-chop. Saturday, 8th August, shows a bit of a pulse—4ft in the morning, 4ft in the afternoon, both from the west with a 9-second period. The combined energy jumps to 205 and 284 (moderate), but the wind is still cross or cross-onshore at 9 to 16 mph. The morning is the better bet with a gentle cross-shore, but it’s still “poor surf conditions.” It’s a tease, really.
From Sunday, 9th August, onwards, it’s a slide into the gutter. Swell drops to 2ft, then 1ft, then 0.7ft by 10th August. Wind is from the north and north-northwest at 16 to 19 mph, creating a lumpy cross-chop. The energy is negligible—18, 39, 62. There’s a little bump on 11th and 12th August with 3ft to 3ft swells and energy around 191 to 237, but the wind is still a moderate cross-shore from the north at 16 mph. The period is 9 to 10 seconds, so it’s not terrible, but the wind angle is never clean. Then from 13th August, the wind goes nuclear—22 to 25 mph from the north and north-northwest, with swell dropping to 0.3ft to 1.0ft. The energy is 10 to 30. That’s kite-surfing territory, not paddling. The long-period swells on 15th and 16th August (20 seconds and 18 seconds) are from the southwest and south-southwest, but they’re only 0.3ft to 0.7ft—useless. The water temp is about average for the time of year.
So, the honest truth: there’s nothing to get excited about here. The whole 16 days is a gap of poor surf, with no standouts. The wind is always wrong, the swell is small, and the energy is low. You’d be better off waiting for the next system or checking another break. The forecast can change, but for now, it’s a flat, choppy mess.
Rusty.
