Tides in Clearwater Beach
Today's high and low tides
- ▲ High tide 12:19 am 3.4 ft · coef. 92
- ▼ Low tide 7:57 am -0.4 ft
- ▲ High tide 2:53 pm 2.2 ft · coef. 87
- ▼ Next low tide 7:03 pm 1.5 ft
↓ Falling The tide is falling. 1 h 9 min to low tide at 7:03 pm.
Tide coefficient 92 for the 12:19 am high tide and 87 for the 2:53 pm high tide. Spring tides. The water rises and falls 3.9 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 August 12 (3.6 ft) and the lowest, on January 3 (-1.3 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 26 (coefficient 98, 3.6 ft range). The smallest, on October 18 (coefficient 29, 1.9 ft).

The sea at Clearwater Beach
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.1 ft
- Significant2.2 ft
- Highest expectedHighest4.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.6 ft. Before heading out, expect waves of up to 4.6 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 4 s, from the north (slight).
Water temperature

Surf in Clearwater Beach today
Surf today
Poor- 0.9–1.4 ft surf at the shore, small: good for learning or a longboard
- 1.3 ft swell at 4 s from the north-northwest, short: weak, messy waves
- 1.6 ft wind swell at 3 s: messy waves
- Moderate offshore wind (14 mph): it holds up and grooms the waves
- Falling tide (low tide at 7:03 pm)
Rip current risk today: moderate · tomorrow: low (NWS)
Dangerous rip currents are possible: swim only near a lifeguard and follow the flags. If one pulls you out, swim parallel to the shore.
Surf height from the NWS, today: up to 1.0 ft
- Light: First light 7:16 am · sunrise 7:40 am · sunset 6:50 pm · last light 7:14 pm
- Tide: high 12:19 am (3.4 ft), low 7:57 am (-0.4 ft), high 2:53 pm (2.2 ft) and low 7:03 pm (1.5 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 73.2 °F: a rash guard or a neoprene top.
- Energy: 8 kJ · Low power
Today’s surf at a glance
The best window, 3:00 pm to 7:00 pm, has light offshore wind, though with small waves, a short-period swell and wind 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.
Diving in Clearwater Beach today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (7:57 am): little current from 7:40 am to 8:12 am
- 1.4 ft swell at 4 s from the north-northwest: barely any surge
- Moderate offshore wind (14 mph): it pushes surface swimmers away from shore
- 0.2 mph current toward the south, weak (model)
- Daylight
- Slack water today: high tide 12:19 am (12:00–12:40 am), low tide 7:57 am (7:40–8:12 am), high tide 2:53 pm (2:10–3:50 pm) and low tide 7:03 pm (6:30–7:30 pm)
- Likely visibility: good. The sea has been calm and there's been little rain. Based on the last 24 hours of data.
- Water at 73.2 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 7:14 pm. Waning gibbous (91%), rising at 8:50 pm: a bright night.
Your diving day at a glance
The best window, 7:40 am to 8:30 am, combines slack water at low tide, little swell and weak current, though with moderate wind. Also worth a look from 1:20 pm to 3:50 pm, with slack water at high tide, little swell and the sun high, though with moderate wind 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.

Moon phase and position
Today the moon is 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:07–4:07 am Major · the moon passes overhead · high activity
- 2:39–4:39 pm Major · the moon passes underfoot · high activity
- 9:57–10:57 am Minor · moonset · medium activity
- 8:20–9:20 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 1.1 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
