Table - best surf conditions forecast for Barra da Lagoa over the next 16 days.
Hey, Rusty here for Barra da Lagoa. This spot's great for beginners – fairly consistent but often crowded. Water temp is 63°F, which is a couple degrees cooler than normal, so you'll want a wetsuit.
Over the next couple weeks, it's a mixed story. Tuesday 7 July morning offers some chest‑high SE swell around 4 ft with a 10‑second period, but the cross‑off south wind makes it messy. Combined energy is moderate at 250. Wednesday and Thursday stay small and chopped up – not worth it.
Friday 10 July brings a nicer window. Morning is glassy with a tiny 2 ft ESE swell but a long 14‑second period – groundswell – energy 249. It's clean but small. The afternoon picks up to 3 ft, same long period, cross‑off wind, and energy hits 444 – much more appealing on a longboard.
Saturday 11 July sees the biggest swell: 5 ft ESE, 13‑second period, energy 663. That's got some push, but the cross wind keeps it from being perfect.
The real standout is Sunday morning, 12 July. We get a 4 ft SSE swell with a solid 12‑second period, energy 594, and the wind goes offshore from the WSW – dead glassy. That's your cleanest, most lined‑up surf of the whole 16 days. Expect waist‑to‑chest high waves with good shape. Crowds will be there – it's a Sunday after all – but if you get out early, you'll score.
After Sunday afternoon, it goes downhill. Monday and Tuesday are messy, wind‑affected. From Thursday 16 July onward, the swell drops to under 2 ft with short period and cross‑onshore winds – basically flat or junk. The entire second week is a dud. So mark your calendar for that Sunday morning session – everything else is pretty average.
