Onshore wind. The coast faces east and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.

Satellite (yesterday) 73.8 °F measured 2.6 mi away

The satellite measured 3.6 °F less yesterday than the model gives now: the water is probably colder than the forecast says.

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 79.0 °F by Tuesday 3.

Water warmer than normal for late October (+3.3 °F).

Today’s surf at a glance

The best window, 5:00 am to 9:00 am, has a good size and glassy water, though with a short-period swell. 2:00 pm to 6:00 pm can also work, with a good size, though with a short-period swell.

An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Solunar periods

Today's activity: medium
  • 12:13–2:13 am Major · the moon passes overhead · high activity
  • 12:45–2:45 pm Major · the moon passes underfoot · high activity
  • 6:11–7:11 am Minor · moonset · medium activity
  • 8:21–9:21 pm Minor · moonrise · medium activity

According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

Water depth

Gentle slope

The bottom slopes gently: 16 ft deep 0.35 mi from shore and 33 ft at 0.4 mi.

From the shoreline (2.3 mi from São João da Barra) out to sea, heading east.

How far from shore

  • 16 ft deep0.35 mi
  • 33 ft deep0.4 mi
  • 66 ft deep0.5 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.35 mi): cast far from the beach and fish the high tide, when there is more water close in.
  • Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
  • Diving. Shore diving works here: 33 ft at 0.4 mi and 66 ft at 0.5 mi from shore.

Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
