Where this tide comes from
Playa de Arra has no tide station nearby: its tide is calculated with the global EOT20 model, from the nearest model cells offshore (the first one 3.3 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.

The waves you may find
- Most commonMost common3.1 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 12 ft. Before heading out, expect waves of up to 12 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces north 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: 6.4 ft with a period of 11 s, from the north-northwest (moderate).

Today’s surf at a glance
The best window, 7:22 am to 11:00 am, has a good size and glassy water.
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.

Your diving day at a glance
The best window, 5:30 pm to 6:20 pm, combines slack water at high tide, light wind and weak current, though with some swell. Also worth a look from 11:50 am to 12:40 pm, 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.

Solunar periods
Today's activity: medium- 2:46–4:46 am Major · the moon passes overhead · high activity

- 11:36 am–12:36 pm Minor · moonset · medium activity
- 8:01–9:01 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.

- 66 ft deep0.75 mi
- 164 ft deep1.8 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 21 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 1,150 ft and 66 ft at 0.75 mi from shore.
Right by the shore the bottom may drop even faster than shown.
