Your day at a glance

The best window, 5:20 pm to 6:10 pm, combines the 5:35 pm low tide, sunset and some swell. Also worth a try from 2:10 am to 2:50 am, with the 3:10 am low tide, a major period and some swell, though with moderate wind. Also good from 9:30 am to 11:30 am, with the 10:34 am high tide and some swell.

Species with the most records nearby: yellowtail snapper, lane snapper, gray snapper and mutton snapper. October is one of the months when these are seen most: mutton snapper and almaco jack. What you can catch

Today's high and low tides

  • ▼ Low tide 3:10 am -0.1 ft
  • ▲ High tide 10:34 am 1.6 ft · coef. 84
  • ▼ Low tide 5:35 pm 0.5 ft

↑ Rising The tide is rising. 3 h 45 min to high tide at 9:40 pm.

Tide coefficient 84 for the 10:34 am high tide and 81 for the 9:40 pm high tide. Average coefficient. The water rises and falls 1.6 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 November 25 (1.6 ft) and the lowest, on May 17 (-0.4 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 8 to 10 (coefficient 87, 1.2 ft range). The smallest, from October 17 to 19 (coefficient 43, 0.9 ft).

Sea and waves

The sea at Isabell II

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · gentle breeze, Beaufort 3
Waves 2.6 ft · 5.4 s from the east-southeast (115°)
Swell 1.7 ft · 4.0 s from the south-southeast
Current 1.2 mph toward the NNW

The waves you may find

  • Most commonMost common1.3 ft
  • Significant2.6 ft
  • Highest expectedHighest5.4 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.4 ft. Before heading out, expect waves of up to 5.4 ft.

Wind on the coast and offshore

On the coast 8 mph SE · gusts 13

The model doesn't separate offshore wind here: it's the same as on the coast.

Cross-offshore wind. The coast faces north and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

Your diving day at a glance

The best window, 9:50 am to 11:30 am, combines slack water at high tide, light wind and the sun high, though with current. Also worth a look from 4:40 pm to 5:30 pm, with slack water at low tide and light wind, though with 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.

Solunar periods

Today's activity: medium
  • 12:55–2:55 am Major · the moon passes overhead · high activity
  • 1:27–3:27 pm Major · the moon passes underfoot · high activity
  • 8:19–9:19 am Minor · moonset · medium activity
  • 7:33–8:33 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

Gentle slope

The bottom slopes gently: 16 ft deep 0.3 mi from shore and 33 ft at 0.45 mi.

From the shoreline (0.45 mi from Isabell II) out to sea, heading north.

How far from shore

  • 16 ft deep0.3 mi
  • 33 ft deep0.45 mi
  • 66 ft deep2.4 mi
  • 164 ft deepnot within 3.1 mi

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. 33 ft deep 0.45 mi from shore; 66 ft is far out (2.4 mi): for deeper dives, go by boat.

Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
