Tides in San Juan del Sur
Today's high and low tides
- ▲ High tide 3:38 am 8.3 ft · coef. 92
- ▼ Low tide 10:04 am -0.6 ft
- ▲ Next high tide 4:04 pm 7.5 ft · coef. 93
- ▼ Low tide 10:17 pm -0.2 ft
↑ Rising The tide is rising. 1 h 10 min to high tide at 4:04 pm.
Tide coefficient 92 for the 3:38 am high tide and 93 for the 4:04 pm high tide. Spring tides. The water rises and falls 9.0 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 May 18 (8.6 ft) and the lowest, on April 19 (-0.9 ft).
Semidiurnal: two high and two low tides a day, of similar height.
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 come from October 27 to 29 (coefficient 93, 9.0 ft range). The smallest, on October 20 (coefficient 39, 3.7 ft).

Where this tide comes from
Tides from the San Juan Del sur station (NOAA), 0.9 mi from San Juan del Sur. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the La Union (Cutuco) reference station with the official corrections.

The sea at San Juan del Sur
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.1 ft
- Highest expectedHighest6.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.1 ft. Before heading out, expect waves of up to 6.1 ft.
Wind on the coast and offshore
Offshore wind. The coast faces west 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 Sunday 1: 4.2 ft with a period of 14 s, from the southwest (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.
Water warmer than normal for late October (+4.7 °F).

Surf in San Juan del Sur today
Surf today
Very good- 2.5–3.8 ft surf at the shore, a fun size for most surfers
- 2.4 ft swell at 12 s from the west-southwest, clean
- Light offshore wind (11 mph): it holds up and grooms the waves
- Rising tide (high tide at 4:04 pm)
- Light: First light 5:13 am · sunrise 5:34 am · sunset 5:20 pm · last light 5:41 pm
- Tide: high 3:38 am (8.3 ft), low 10:04 am (-0.6 ft), high 4:04 pm (7.5 ft) and low 10:17 pm (-0.2 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 86.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 159 kJ · Medium power
Today’s surf at a glance
The best window, 2:00 pm to 5:41 pm, has a good size, a clean swell and light offshore wind.
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 San Juan del Sur today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (4:04 pm): little current from 3:30 pm to 4:50 pm
- 2.5 ft swell at 12 s from the west-southwest: some surge on the bottom
- Light offshore wind (11 mph)
- 1.1 mph current toward the northwest (model)
- Daylight
- Slack water today: high tide 3:38 am (3:10–4:20 am), low tide 10:04 am (9:40–10:30 am), high tide 4:04 pm (3:30–4:50 pm) and low tide 10:17 pm (9:50–10:40 pm)
- Likely visibility: good. Swell (up to 2.6 ft at 12 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 86.0 °F: a shorty or a rash guard.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:41 pm. Waning gibbous (91%), rising at 7:44 pm: a bright night.
Your diving day at a glance
The best window, 2:40 pm to 4:30 pm, combines slack water at high tide and light wind, though with some swell and 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.

The moon in San Juan del Sur
Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 12:20–2:20 am Major · the moon passes overhead · high activity
- 12:52–2:52 pm Major · the moon passes underfoot · high activity
- 7:29–8:29 am Minor · moonset · medium activity
- 7:14–8:14 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
Deepens quicklyThe bottom deepens quickly: 33 ft of water 900 ft from shore. It reaches 164 ft at 1.9 mi.

- 16 ft deep750 ft
- 33 ft deep900 ft
- 66 ft deep0.45 mi
- 164 ft deep1.9 mi
For fishing, swimming and diving
- Shore fishing. 33 ft of water just 900 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 900 ft and 66 ft at 0.45 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
