Tides in Matecumbe
Today's high and low tides

- ▼ Low tide 6:19 pm 0.5 ft
↑ Rising The tide is rising. 5 h 9 min to high tide at 12:01 am.
Tide coefficient 90 for the 12:51 pm high tide. Spring tides. The water rises and falls 1.0 ft between the highest high and the lowest low: an average 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 October 29 (1.5 ft) and the lowest, on May 17 (-0.4 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 25 to 27 (coefficient 95, 1.6 ft range). The smallest, from October 18 to 19 (coefficient 35, 0.8 ft).

Where this tide comes from
Tides from the Little Basin station (NOAA), 0.1 mi from Matecumbe. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Key West reference station with the official corrections.

The sea at Matecumbe
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.3 ft
- Significant2.7 ft
- Highest expectedHighest5.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.6 ft. Before heading out, expect waves of up to 5.6 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-shore wind. The coast faces southeast and the wind blows along the shore: drift and current run parallel to the beach.

Waves stay much the same all week. The biggest waves arrive on Wednesday 28: 3.9 ft with a period of 5 s, from the northeast (slight).

Surf in Matecumbe today
Surf today
Poor- 1.0–1.5 ft surf at the shore, small: good for learning or a longboard
- 1.4 ft swell at 4 s from the east-northeast, short: weak, messy waves
- Light offshore wind (7 mph): it holds up and grooms the waves
- Rising tide (high tide at 12:51 pm)
- Light: First light 7:04 am · sunrise 7:28 am · sunset 6:45 pm · last light 7:08 pm
- Tide: low 7:03 am (-0.0 ft), high 12:51 pm (0.9 ft) and low 6:19 pm (0.5 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 82.2 °F–83.3 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 11 kJ · Low power
Today’s surf at a glance
The best window, 7:04 am to 11:00 am, has light offshore wind, though with small waves and 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.
Diving in Matecumbe today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (12:51 pm): little current from 12:20 pm to 2:20 pm
- 1.0 ft swell at 6 s from the northeast: barely any surge
- Light cross-shore wind (10 mph)
- 0.8 mph current toward the west-northwest (model)
- Sun high: more light underwater
- Slack water today: high tide 11:15 pm (10:40 pm–12:10 am), low tide 7:03 am (6:20–7:30 am), high tide 12:51 pm (12:20–2:20 pm), low tide 6:19 pm (5:00–6:40 pm) and high tide 12:01 am (11:30 pm–12:50 am)
- Likely visibility: fair. Swell (up to 3.1 ft at 6 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 82.2–83.3 °F: a shorty or a rash guard.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 7:08 pm. Waning gibbous (91%), rising at 8:49 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 2:20 pm, combines slack water at high tide, little swell, light wind and the sun high, though with current. Also worth a look from 3:20 pm to 6:20 pm, with slack water at low tide, little swell and weak current, though with moderate wind. Also worth a look from 7:30 am to 8:10 am, with light wind, 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 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:58–3:58 am Major · the moon passes overhead · high activity
- 2:30–4:30 pm Major · the moon passes underfoot · high activity
- 9:39–10:39 am Minor · moonset · medium activity
- 8:19–9:19 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. Shallow, gradual bottom (16 ft at 1.6 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
