Today at Drift River Terminal, AK
Today's predicted high and low waters, sunrise and sunset for Drift River Terminal, AK load here from NOAA. Without JavaScript they cannot be shown: NOAA's own table for station 9455741 is at tidesandcurrents.noaa.gov. Everything else on this page is measured and does not change from day to day.
What the tide does at Drift River Terminal, AK
Across the 1410 high and low waters NOAA predicts here for 2027, high water averages 17.25 ft above MLLW and low water 2.27 ft — a mean range of 14.98 ft. Taking each day's higher high and lower low, which is the swing someone standing on the shore actually sees, the average is 17.9 ft.
On 93% of days in 2027 there are two high waters and on the remaining 25 days only one. Where there are two, they differ in height by 1.74 ft on average. Successive high waters are 12h 25m apart on average.
The largest daily swing of 2027 is 28.61 ft on 23 January 2027 and the smallest is 7.1 ft on 8 October 2027 , a factor of 4.0 between the biggest spring tide and the smallest neap.

What MLLW means here
Every height on this page is feet above MLLW — mean lower low water, the chart datum NOAA publishes tide predictions against. It is the average of the lower of each day's low waters, taken over a 19-year period, so zero here is neither the sea bed nor the average sea level: it is a level the water drops below regularly. At Drift River Terminal, AK, 208 of the 705 low waters predicted for 2027 — 30% of them — fall below zero, the lowest being -6.41 ft on 5 July 2027.
Practically: a chart showing 6 ft of water here means about 6 ft at a mean lower low water and about 23.9 ft at a mean higher high. Add the predicted height for the moment you care about to the charted depth.
Where these predictions come from
This is a subordinate station. NOAA does not run a separate harmonic analysis here; it takes the predictions for SELDOVIA, Kachemak Bay, AK, 126 km (78 miles) away and shifts them. High water arrives 1 h 39 min later than the reference station and low water 2 h 4 min later than it. Heights are the reference station's multiplied by 1.01 at high water and 1.18 at low water.
Those constants are NOAA's own, published for station 9455741 (reference 9455500). They are why a subordinate station's table is never simply its neighbour's.
Daylight at this latitude
Drift River Terminal, AK sits at 60.5550° N. The longest day of 2027 here is 19h 05m of daylight on 21 June 2027; the shortest is 5h 41m on 21 December 2027 — a difference of 13h 24m.
Day lengths are computed with NOAA's published solar algorithm from the station's latitude and longitude. Clock times for sunrise and sunset are deliberately not printed here: they depend on the station's UTC offset, and this site takes that offset from NOAA's own answers rather than from a timezone table — so it is the live panel above, which has them, that shows the times.
