Today at Point Brown, WA
Today's predicted high and low waters, sunrise and sunset for Point Brown, WA load here from NOAA. Without JavaScript they cannot be shown: NOAA's own table for station 9441156 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 Point Brown, WA
Across the 1411 high and low waters NOAA predicts here for 2027, high water averages 8.58 ft above MLLW and low water 1.52 ft — a mean range of 7.06 ft. Taking each day's higher high and lower low, which is the swing someone standing on the shore actually sees, the average is 9.27 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 1.71 ft on average. Successive high waters are 12h 25m apart on average.
The largest daily swing of 2027 is 13.67 ft on 22 January 2027 and the smallest is 2.96 ft on 5 November 2027 , a factor of 4.6 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 Point Brown, WA, 176 of the 706 low waters predicted for 2027 — 25% of them — fall below zero, the lowest being -2.96 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 15.3 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 Toke Point, WA, 30 km (18 miles) away and shifts them. High water arrives 9 min earlier than the reference station and low water 24 min earlier than it. Heights are the reference station's multiplied by 1.06 at high water and 1.04 at low water.
Those constants are NOAA's own, published for station 9441156 (reference 9440910). They are why a subordinate station's table is never simply its neighbour's.
Daylight at this latitude
Point Brown, WA sits at 46.9500° N. The longest day of 2027 here is 15h 53m of daylight on 21 June 2027; the shortest is 8h 31m on 21 December 2027 — a difference of 7h 22m.
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.
