- ▲ Next high tide 9:07 pm 2.1 ft · coef. 117
↑ Rising The tide is rising. 3 h 14 min to high tide at 9:07 pm.
Tide coefficient 117 for the 9:07 pm high tide. Big spring tides. The water rises and falls 2.2 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 October 29 (2.1 ft) and the lowest, on January 2 (-1.0 ft).
Diurnal: one high and one low tide a day most days.
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 28 to 30 (coefficient 118, 2.2 ft range). The smallest, on October 23 (coefficient 20, 0.6 ft).

Where this tide comes from
Tides from the Port Isabel station (NOAA), 1.0 mi from Port Isabel. Times and heights are its predictions.

The sea at Port Isabel
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.2 ft
- Significant2.4 ft
- Highest expectedHighest5.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.0 ft. Before heading out, expect waves of up to 5.0 ft.
Wind on the coast and offshore
Onshore wind. The coast faces east and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Tuesday 3: 3.1 ft with a period of 5 s, from the southeast (slight).
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 in Port Isabel today
Surf today
Poor- 1.7–2.7 ft surf at the shore, a fun size for most surfers
- 2.3 ft swell at 6 s from the east, short: weak, messy waves
- Almost no wind (3 mph): glassy water
- First or last light of the day
- Falling tide (low tide at 11:13 am)
- Light: First light 7:12 am · sunrise 7:35 am · sunset 6:50 pm · last light 7:13 pm
- Tide: low 11:13 am (-0.1 ft) and high 9:07 pm (2.1 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 79.9 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 33 kJ · Low power
Today’s surf at a glance
The best window, 7:12 am to 10:00 am, has a good size and glassy water, though with a short-period swell. 11:00 am to 12:00 pm can also work, with a good size, though with 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 Port Isabel today
Diving and snorkeling today

- 2.4 ft swell at 6 s from the east: some surge on the bottom
- Light onshore wind (8 mph)
- 0.0 mph current toward the east, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 11:13 am (10:58–11:30 am) and high tide 9:07 pm (8:20–10:30 pm)
- Likely visibility: good. Swell (up to 3.1 ft at 6 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 79.9 °F: a shorty or a rash guard.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 7:13 pm. Waning gibbous (91%), rising at 8:55 pm: a bright night.
Your diving day at a glance
The best window, 10:30 am to 11:50 am, combines slack water at low tide, light wind, weak current and the sun high.
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 226,426 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
- 9:52–10:52 am Minor · moonset · medium activity
- 8:25–9:25 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. Very shallow: the water doesn't reach 16 ft within 1.8 mi. Cast far from the beach, ideally around high tide.
- 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 1.8 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 1.8 mi out.
