↓ Falling The tide is falling. 5 h 27 min to low tide at 1:08 pm.
Tide coefficient 93 for the 7:37 am high tide and 88 for the 7:08 pm high tide. Spring tides. The water rises and falls 6.3 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 14 (5.5 ft) and the lowest, on December 25 (-1.6 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 26 to 27 (coefficient 104, 6.4 ft range). The smallest, on October 19 (coefficient 26, 2.0 ft).

Where this tide comes from
San Isidro has no station of its own, so we use the tide at Legazpi (TICON-4), 14 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The sea at San Isidro
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.2 ft
- Significant0.5 ft
- Highest expectedHighest1.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.0 ft. Before heading out, expect waves of up to 1.0 ft.
Wind on the coast and offshore
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.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 0.5 ft with a period of 2 s, from the northeast (smooth).
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.

Your diving day at a glance
The best window, 12:00 pm to 2:10 pm, combines slack water at low tide, little swell, light wind and the sun high, though with current. Also worth a look from 6:50 am to 8:20 am, with slack water at high tide, little swell 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.

Moon phase and position
Today the moon is 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:48–2:48 am Major · the moon passes overhead · high activity
- 1:20–3:20 pm Major · the moon passes underfoot · high activity
- 8:01–9:01 am Minor · moonset · medium activity
- 7:38–8:38 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.
