Warm: very pleasant.
- Sun & sunscreen UV 6 · SPF 50
Max UV 6 (high): SPF 50 sunscreen, reapplied every 2 hours.
- Wind 13 mph
Moderate offshore wind (13 mph). Skip the inflatables: offshore wind carries them out to sea.
- Tide & sand 9:12 pm
Low tide at 9:38 am and 9:12 pm: that's when there's the most sand. High tide at 2:26 am and 4:15 pm.
The best window, 1:00 pm to 6:00 pm, brings sunshine, beach weather, a calm sea and water at 78 °F, though with moderate offshore wind. 9:00 am to 12:00 pm can also work, with sunshine, beach weather, a calm sea, water at 78 °F and low tide at 9:38 am, though with moderate offshore wind.
We don't have data on jellyfish, sargassum or beach closures: ask the lifeguard or check with the local beach authority. How it works · The next 7 days

Tides in Marco
Today's high and low tides
- ▲ High tide 2:26 am 3.4 ft · coef. 92
- ▼ Low tide 9:38 am -0.3 ft
- ▲ High tide 4:15 pm 2.4 ft · coef. 88
- ▼ Next low tide 9:12 pm 1.4 ft
↓ Falling The tide is falling. 2 h 22 min to low tide at 9:12 pm.
Tide coefficient 92 for the 2:26 am high tide and 88 for the 4:15 pm high tide. Spring tides. The water rises and falls 3.7 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on November 26 (3.4 ft) and the lowest, on January 3 (-0.9 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 26 to 27 (coefficient 95, 3.6 ft range). The smallest, from October 18 to 19 (coefficient 37, 1.9 ft).

The sea at Marco
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.6 ft
- Highest expectedHighest3.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.3 ft. Before heading out, expect waves of up to 3.3 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces west 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 stay much the same all week. The biggest waves arrive on Wednesday 28: 2.4 ft with a period of 3 s, from the north (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 80.5 °F by Tuesday 3.

- Rising tide (high tide at 4:15 pm)
It’s flat today: almost no waves reach this coast.
Rip current risk tomorrow: low (NWS)

The best window, 2:00 pm to 6:00 pm, 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.
Diving in Marco today
Diving and snorkeling today

- Likely visibility: good. The sea has been calm and there's been little rain. Based on the last 24 hours of data.
- Water at 77.9 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 7:12 pm. Waning gibbous (91%), rising at 8:51 pm: a bright night.
Your diving day at a glance
The best window, 3:10 pm to 4:30 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 8:40 am to 9:30 am, with slack water at low tide, little swell, light wind and weak 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 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:03–4:03 am Major · the moon passes overhead · high activity
- 2:35–4:35 pm Major · the moon passes underfoot · high activity
- 9:47–10:47 am Minor · moonset · medium activity
- 8:21–9:21 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
- Shore fishing. About 11 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- 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. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
