↓ Falling The tide is falling. 2 h 31 min to low tide at 8:23 pm.
Tide coefficient 87 for the 3:35 am high tide and 90 for the 2:19 pm high tide. Spring tides. The water rises and falls 1.6 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 December 28 (1.3 ft) and the lowest, on December 29 (-1.4 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. mean sea level
Tide coefficient and range in October
The biggest tides of the month come from October 29 to 31 (coefficient 94, 1.8 ft range). The smallest, from October 19 to 20 (coefficient 36, 1.0 ft).

Where this tide comes from
Montevideo has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 2.2 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.
Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.
The sea at Montevideo
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.3 ft
- Significant0.7 ft
- Highest expectedHighest1.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.3 ft. Before heading out, expect waves of up to 1.3 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces south and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Tuesday 3: 2.5 ft with a period of 4 s, from the east-southeast (slight).
Water temperature
Water temperature →The satellite measured 4.3 °F less yesterday than the model gives now: the water is probably colder than the forecast says.
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 66.5 °F by Tuesday 3.
Water about normal for late October.

Today’s surf at a glance
The best window, 5:20 am to 9:00 am, has glassy water, 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, 11:40 am to 2:40 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 7:20 am to 8:20 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 226,432 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:16–3:16 am Major · the moon passes overhead · high activity
- 1:48–3:48 pm Major · the moon passes underfoot · high activity
- 6:37–7:37 am Minor · moonset · medium activity
- 10:03–11:03 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 0.85 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.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
