Tide coefficient 93 for the 3:39 am high tide and 93 for the 4:09 pm high tide. Spring tides. The water rises and falls 10.9 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 May 18 (10.1 ft) and the lowest, on April 19 (-1.1 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, 10.9 ft range). The smallest, from October 19 to 20 (coefficient 39, 4.6 ft).

Where this tide comes from
Playa Conchal has no station of its own, so we use the tide at Bahia de Culebra (NOAA), 19 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. It is a NOAA subordinate station: its times and heights come from the Puntarenas reference station with the official corrections.

The sea at Playa Conchal
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.9 ft
- Significant3.7 ft
- Highest expectedHighest7.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.4 ft. Before heading out, expect waves of up to 7.4 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northwest 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 Sunday 1: 4.8 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.

Surf today
Good- 1.9–2.9 ft surf at the shore, a fun size for most surfers
- 2.6 ft swell at 12 s from the west-southwest, clean; it hits this coast at an angle
- Almost no wind (3 mph): glassy water
- Rising tide (high tide at 4:09 pm)
- Light: First light 5:12 am · sunrise 5:33 am · sunset 5:20 pm · last light 5:42 pm
- Tide: high 3:39 am (10.1 ft), low 9:54 am (-0.8 ft), high 4:09 pm (9.2 ft) and low 10:06 pm (-0.1 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 86.7 °F–87.6 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 187 kJ · Medium power
Today’s surf at a glance
The best window, 10:00 am to 2:00 pm, has a good size, a clean swell and glassy water. 5:00 pm to 5:42 pm also works, with a good size and a clean 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 Playa Conchal today

- Night dive: dark from 5:42 pm. Waning gibbous (91%), rising at 7:46 pm: a bright night.
Your diving day at a glance
The best window, 9:00 am to 10:50 am, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 3:30 pm to 4:50 pm, with slack water at high tide, light wind and weak current, though with some swell.
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.

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
- 7:27–8:27 am Minor · moonset · medium activity
- 7:16–8:16 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 0.55 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 near shore: you only reach 33 ft at 0.65 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
