↑ Rising The tide is rising. 2 h 39 min to high tide at 9:38 pm.
Tide coefficient 87 for the 9:29 am high tide and 85 for the 9:38 pm high tide. Average coefficient. The water rises and falls 6.6 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 June 15 (6.5 ft) and the lowest, on December 25 (-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 came from October 26 to 28 (coefficient 89, 6.6 ft range). The smallest, from October 18 to 19 (coefficient 41, 3.3 ft).

The sea at Yaupon Beach
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.1 ft
- Significant4.1 ft
- Highest expectedHighest8.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.5 ft. Before heading out, expect waves of up to 8.5 ft.
Wind on the coast and offshore
Offshore wind. The coast faces south 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 stay much the same all week. The biggest waves arrive on Thursday 29: 4.4 ft with a period of 6 s, from the east (moderate).
Water temperature
Water temperature →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 69.5 °F by Tuesday 3.

Surf in Yaupon Beach today
Surf today
Poor- 1.7–2.7 ft surf at the shore, a fun size for most surfers
- 3.1 ft swell at 6 s from the east-southeast, short: weak, messy waves; it hits this coast at an angle
- Moderate offshore wind (16 mph): it holds up and grooms the waves
- Rising tide (high tide at 9:38 pm)
Rip current risk today: low · tomorrow: low (NWS)
Rip currents can still form near jetties, piers and reefs: swim near a lifeguard.
Surf height from the NWS, today: 1.0 ft
- Light: First light 7:03 am · sunrise 7:28 am · sunset 6:23 pm · last light 6:49 pm
- Tide: low 3:08 am (-0.2 ft), high 9:29 am (6.4 ft), low 3:54 pm (0.2 ft) and high 9:38 pm (5.0 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 68.0 °F: a springsuit or a 2 mm fullsuit.
- Energy: 86 kJ · Low power
Today’s surf at a glance
The best window, 3:00 pm to 6:49 pm, has light offshore wind, though with a short-period swell. 12:00 pm to 2:00 pm can also work, with light offshore wind, 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.
Diving in Yaupon Beach today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (9:29 am): little current from 9:10 am to 9:50 am
- 2.6 ft swell at 5 s from the east: some surge on the bottom
- Light offshore wind (12 mph)
- 0.1 mph current toward the south, weak (model)
- Daylight
- Slack water today: low tide 3:08 am (2:40–3:30 am), high tide 9:29 am (9:10–9:50 am), low tide 3:54 pm (3:30–4:20 pm) and high tide 9:38 pm (9:10–10:10 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 68.0 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:49 pm. Waning gibbous (91%), rising at 8:12 pm: a bright night.
Your diving day at a glance
The best window, 8:30 am to 9:30 am, combines slack water at high tide, 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 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:48–3:48 am Major · the moon passes overhead · high activity
- 2:19–4:19 pm Major · the moon passes underfoot · high activity
- 9:54–10:54 am Minor · moonset · medium activity
- 7:42–8:42 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 0.3 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 2.2 mi. For dives deeper than 33 ft, go by boat.
