↑ Rising The tide is rising. 1 h 45 min to high tide at 3:45 am.
Tide coefficient 73 for the 3:45 am high tide and 64 for the 3:19 pm high tide. Average coefficient. The water rises and falls 3.0 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
São Sebastião has no station of its own, so we use the tide at Ubatuba (TICON-4), 26 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.

Your diving day at a glance
The best window, 10:30 am to 12:00 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 5:20 am to 7:10 am, with light wind and weak current. Also good from 2:40 pm to 3:50 pm, with slack water at high tide, light wind and weak current.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.

The moon in São Sebastião
Moon phase and position
Today the moon is 226,718 mi away and looks 32′ 44″ across.
Solunar periods
Today's activity: medium- 1:35–3:35 am Major · the moon passes overhead · high activity
- 2:07–4:07 pm Major · the moon passes underfoot · high activity
- 7:24–8:24 am Minor · moonset · medium activity
- 9:50–10:50 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.
