Today at Upper Golovnin Lagoon, AK

Today's predicted high and low waters, sunrise and sunset for Upper Golovnin Lagoon, AK load here from NOAA. Without JavaScript they cannot be shown: NOAA's own table for station 9468841 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 Upper Golovnin Lagoon, AK

Across the 731 high and low waters NOAA predicts here for 2027, high water averages 2.84 ft above MLLW and low water 0.16 ft — a mean range of 2.68 ft. Taking each day's higher high and lower low, which is the swing someone standing on the shore actually sees, the average is 2.69 ft.

On 2% of days in 2027 there are two high waters and on the remaining 347 days only one. Where there are two, they differ in height by 0.23 ft on average. Successive high waters are 23h 57m apart on average.

The largest daily swing of 2027 is 4.68 ft on 7 June 2027 and the smallest is 0.51 ft on 30 September 2027 , a factor of 9.2 between the biggest spring tide and the smallest neap.

Every figure above is computed from NOAA's published predictions for station 9468841 for the whole of 2027 (365 days, 731 tides), not from a regional average or an estimate.

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 Upper Golovnin Lagoon, AK, 138 of the 366 low waters predicted for 2027 — 38% of them — fall below zero, the lowest being -0.98 ft on 18 November 2027.

Practically: a chart showing 6 ft of water here means about 6 ft at a mean lower low water and about 8.7 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 reference station: NOAA computes its predictions directly, from a harmonic analysis of water levels measured at this location, rather than by offsetting another station's table.

Daylight at this latitude

Upper Golovnin Lagoon, AK sits at 64.6208° N. The longest day of 2027 here is 21h 36m of daylight on 21 June 2027; the shortest is 3h 50m on 21 December 2027 — a difference of 17h 46m.

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.
