2026 extremes: the highest tide of the year is on September 11 (1.3 ft) and the lowest, on February 3 (-0.3 ft).
Semidiurnal: two high and two low tides a day, of similar height.
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

Where this tide comes from
Sirenuse has no station of its own, so we use the tide at Napoli (TICON-4), 18 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 Sirenuse
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.3 ft
- Significant0.6 ft
- Highest expectedHighest1.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.2 ft. Before heading out, expect waves of up to 1.2 ft.
Wind on the coast and offshore
Offshore wind. The coast faces south and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 3.1 ft with a period of 4 s, from the northwest (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 69.1 °F by Tuesday 3.

Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has light offshore wind, though with barely any waves.
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, 3:00 pm to 5:00 pm, combines slack water at low tide, little swell, light wind and weak current. Also worth a look from 9:40 am to 10:50 am, with slack water at high tide, little swell, light wind and the sun high, though with 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 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:22–2:22 am Major · the moon passes overhead · high activity

- 8:49–9:49 am Minor · moonset · medium activity
- 5:53–6:53 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.

For fishing, swimming and diving

- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
