Today at Explorer Bay, AK
Today's predicted high and low waters, sunrise and sunset for Explorer Bay, AK load here from NOAA. Without JavaScript they cannot be shown: NOAA's own table for station 9461656 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 Explorer Bay, AK
Across the 960 high and low waters NOAA predicts here for 2027, high water averages 4.36 ft above MLLW and low water 0.58 ft — a mean range of 3.78 ft. Taking each day's higher high and lower low, which is the swing someone standing on the shore actually sees, the average is 4.84 ft.
On 33% of days in 2027 there are two high waters and on the remaining 232 days only one. Where there are two, they differ in height by 0.84 ft on average. Successive high waters are 18h 14m apart on average.
The largest daily swing of 2027 is 8.37 ft on 20 January 2027 and the smallest is 0.48 ft on 18 September 2027 , a factor of 17.4 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 Explorer Bay, AK, 220 of the 480 low waters predicted for 2027 — 46% of them — fall below zero, the lowest being -2.23 ft on 6 June 2027.
Practically: a chart showing 6 ft of water here means about 6 ft at a mean lower low water and about 10.8 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 Sweeper Cove, Kuluk Bay, Adak Island, AK, 144 km (89 miles) away and shifts them. High water arrives 2 h 43 min earlier than the reference station and low water 2 h 24 min earlier than it. Heights are the reference station's multiplied by 1.24 at high water and 1.24 at low water.
Those constants are NOAA's own, published for station 9461656 (reference 9461380). They are why a subordinate station's table is never simply its neighbour's.
Daylight at this latitude
Explorer Bay, AK sits at 52.0733° N. The longest day of 2027 here is 16h 45m of daylight on 21 June 2027; the shortest is 7h 44m on 21 December 2027 — a difference of 9h 01m.
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.
