Your day at a glance

The best window, 10:30 am to 12:00 pm, combines the 11:28 am low tide, moonset, a light onshore breeze and some swell. Also worth a try from 9:30 pm to 10:30 pm, with the 10:01 pm high tide, moonrise and some swell, though with moderate wind. Also good from 3:40 pm to 5:30 pm, with a major period, a light onshore breeze and some swell.

Species with the most records nearby: spot, striped mullet, red drum and spotted seatrout. October is one of the months when these are seen most: black drum and ladyfish. What you can catch

Today's high and low tides

  • ▲ High tide 10:01 pm 2.4 ft · coef. 117

↓ Falling The tide is falling. 7 h 22 min to low tide at 11:28 am.

Tide coefficient 117 for the 10:01 pm high tide. Big spring tides. The water rises and falls 2.8 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 (2.4 ft) and the lowest, on June 14 (-1.4 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 29 (coefficient 117, 2.8 ft range). The smallest, on October 23 (coefficient 20, 0.7 ft).

Sea and waves

Sea stateSea state: slight

Slight Douglas 3 · moderate breeze, Beaufort 4
Waves 2.6 ft · 5.7 s from the east (94°)

The waves you may find

  • Most commonMost common1.3 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.3 ft. Before heading out, expect waves of up to 5.3 ft.

Wind on the coast and offshore

On the coast 11 mph SE · gusts 15
Offshore (11 mi ESE)Offshore 13 mph SE · gusts 18

Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.

The best window is 1:00 pm to 4:00 pm, though with a short-period swell. 9:00 am to 10:00 am can also work, though with a short-period swell. 11:00 am to 12:00 pm can also work, though with a short-period swell.

Your diving day at a glance

The best window, 10:50 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.

Solunar periods

Today's activity: medium
  • 3:11–5:11 am Major · the moon passes overhead · high activity

  • 10:59–11:59 am Minor · moonset · medium activity
  • 9:29–10:29 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

Drops off fast

The bottom drops off fast: the water is 33 ft deep just 150 ft from shore.

From the shoreline (0.35 mi from Brazos Santiago Pass) out to sea, heading east.

How far from shore

  • 16 ft deep80 ft
  • 33 ft deep150 ft
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 36 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
  • Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
  • Diving. 33 ft deep 150 ft from shore; 66 ft is far out (beyond 3.1 mi): for deeper dives, go by boat.

Right by the shore the bottom may drop even faster than shown.
