Where this tide comes from
Sirolo has no station of its own, so we use the tide at Ancona (TICON-4), 8.9 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 Sirolo
Sea stateSea state: slight
The waves you may find
- Most commonMost common0.9 ft
- Significant1.8 ft
- Highest expectedHighest3.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.9 ft. Before heading out, expect waves of up to 3.9 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces east and the wind comes off the land at an angle: calmer water near the shore, and bait and boats 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: 5.5 ft with a period of 6 s, from the northeast (moderate).
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 64.9 °F by Tuesday 3.
Water warmer than normal for late October (+3.0 °F).

Today’s surf at a glance
The best window, 4:00 pm to 5:32 pm, has light offshore wind, though with barely any waves. 6:06 am to 10:00 am can also work, with glassy water, though with a short-period swell.
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, 9:50 am to 11:10 am, combines 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- 12:25–2:25 am Major · the moon passes overhead · high activity
- 12:56–2:56 pm Major · the moon passes underfoot · high activity
- 9:04–10:04 am Minor · moonset · medium activity
- 5:44–6:44 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
Gentle slopeThe bottom slopes gently: 16 ft deep 250 ft from shore and 33 ft at 0.45 mi. Right off the beach it already drops to about 20 ft.
From the shoreline (0.45 mi from Sirolo) out to sea, heading east.
How far from shore
- 16 ft deep250 ft
- 33 ft deep0.45 mi
- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 20 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. 33 ft deep 0.45 mi from shore; 66 ft is far out (beyond 3.1 mi): for deeper dives, go by boat.
Right by the shore the bottom may drop even faster than shown.
