Where this tide comes from
São Mamede has no station of its own, so we use the tide at Cascais (TICON-4), 15 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.

Wind on the coast and offshore
Cross-shore wind. The coast faces southeast and the wind blows along the shore: drift and current run parallel to the beach.

Waves ease over the next few days. The biggest waves arrive on Thursday 29: 4.9 ft with a period of 13 s, from the west-northwest (moderate).

Your diving day at a glance
The best window, 3:30 pm to 5:30 pm, combines slack water at high tide, light wind and weak current. Also worth a look from 9:30 am to 11:00 am, with slack water at low tide, light wind, weak current and the sun high, though with some swell.
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 226,641 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:03–4:03 am Major · the moon passes overhead · high activity
- 2:36–4:36 pm Major · the moon passes underfoot · high activity
- 10:33–11:33 am Minor · moonset · medium activity
- 7:39–8:39 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
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 470 ft from shore.
From the shoreline (0.5 mi from São Mamede) out to sea, heading south.
How far from shore
- 16 ft deep260 ft
- 33 ft deep470 ft
- 66 ft deep0.3 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 22 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 470 ft and 66 ft at 0.3 mi from shore.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. Right by the shore the bottom may drop even faster than shown.
