Tide coefficient 90 for the 3:13 am high tide and 83 for the 2:51 pm high tide. Spring tides. The water rises and falls 3.4 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on September 13 (3.7 ft) and the lowest, on August 12 (-1.2 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above MLWS. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLWS
Tide coefficient and range in October
The biggest tides of the month came from October 25 to 26 (coefficient 108, 4.0 ft range). The smallest, on October 18 (coefficient 20, 1.4 ft).

Where this tide comes from
Prainha has no station of its own, so we use the tide at Ubatuba (TICON-4), 20 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The waves you may find
- Most commonMost common1.2 ft
- Significant2.5 ft
- Highest expectedHighest5.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.2 ft. Before heading out, expect waves of up to 5.2 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces east and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Tuesday 3: 3.7 ft with a period of 7 s, from the east (slight).
Water temperature
Water temperature →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 77.6 °F by Tuesday 3.

The moon in Prainha
Moon phase and position
Today the moon is 226,432 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 12:31–2:31 am Major · the moon passes overhead · high activity
- 1:03–3:03 pm Major · the moon passes underfoot · high activity
- 6:24–7:24 am Minor · moonset · medium activity
- 8:44–9:44 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.
