Today at Port Graham: high tide at 9:53 AM (15.2 ft) and 10:00 PM (14.3 ft), low tide at 3:00 AM (2.7 ft) and 3:49 PM (5.2 ft). The National Weather Service forecast for Tuesday is light rain with NE winds 25 to 30 mph, 46°F. Wind that strong can hold water in or push it out, so the real tide may run above or below these predictions. In effect now: Small Craft Advisory. Sunrise is at 8:29 AM and sunset at 5:12 PM.

Where Port Graham is
Port Graham sits at 59.3500° N, 151.8267° W on Cook Inlet, off the Gulf of Alaska, at Port Graham, AK. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is Seldovia, Kachemak Bay (NOAA 9455500), 7.3 mi away, and high and low water here run on average about 11 min earlier than there. The nearest weather station is Seldovia, AK, a shore station reporting wind and, at most sites, water temperature, 7.3 mi away.
The tide at Port Graham
Port Graham has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 16.9 ft, and 14.5 ft between the average high and the average low, a very large tide, among the biggest in the United States. On an average day the higher high tops the lower high by 0.7 ft and the lower low sits 1.7 ft below the other low. For the water around it: Cook Inlet has some of the largest tides in the United States, mixed semidiurnal with ranges near 30 ft at the head of the inlet.
About this station
- High tide reaches Port Graham about 11.1 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- NOAA predicts tides here from Seldovia, Kachemak Bay, station 9455500. High tide comes about 8 min earlier and low tide about 14 min earlier than there.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Port Graham from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 16.9 ft above it and mean sea level 9.0 ft. These datums are controlled from NOAA's Seldovia, AK gauge. Source: NOAA CO-OPS station 9455437, established 1980, gauge removed 2009. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.
