Where this tide comes from
Alcântara has no station of its own, so we use the tide at Ponta da Madeira (São Luís, TICON-4), 11 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 sea at Alcântara
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.0 ft
- Significant2.0 ft
- Highest expectedHighest4.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.1 ft. Before heading out, expect waves of up to 4.1 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 3.2 ft with a period of 5 s, from the east-northeast (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.
Water warmer than normal for late October (+3.2 °F).

Your diving day at a glance
The best window, 2:30 pm to 3:20 pm, combines slack water at low tide, little swell and weak current, though with moderate wind. Also worth a look from 8:30 am to 9:20 am, with slack water at high tide, little swell and the sun high, though with moderate wind and 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,432 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 12:27–2:27 am Major · the moon passes overhead · high activity
- 12:59–2:59 pm Major · the moon passes underfoot · high activity
- 7:07–8:07 am Minor · moonset · medium activity
- 7:51–8:51 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.
