Today at Tide Point, Cypress Island, WA
Today's predicted high and low waters, sunrise and sunset for Tide Point, Cypress Island, WA load here from NOAA. Without JavaScript they cannot be shown: NOAA's own table for station 9448918 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 Tide Point, Cypress Island, WA
Across the 1387 high and low waters NOAA predicts here for 2027, high water averages 7.43 ft above MLLW and low water 2.47 ft — a mean range of 4.96 ft. Taking each day's higher high and lower low, which is the swing someone standing on the shore actually sees, the average is 8.06 ft.
On 90% of days in 2027 there are two high waters and on the remaining 34 days only one. Where there are two, they differ in height by 1.38 ft on average. Successive high waters are 12h 38m apart on average.
The largest daily swing of 2027 is 12.09 ft on 6 June 2027 and the smallest is 1.61 ft on 17 November 2027 , a factor of 7.5 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 Tide Point, Cypress Island, WA, 198 of the 693 low waters predicted for 2027 — 29% of them — fall below zero, the lowest being -3.41 ft on 4 July 2027.
Practically: a chart showing 6 ft of water here means about 6 ft at a mean lower low water and about 14.1 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 Port Townsend, WA, 53 km (33 miles) away and shifts them. High water arrives 31 min later than the reference station and low water 41 min later than it. Heights are the reference station's multiplied by 0.94 at high water and 0.95 at low water.
Those constants are NOAA's own, published for station 9448918 (reference 9444900). They are why a subordinate station's table is never simply its neighbour's.
Daylight at this latitude
Tide Point, Cypress Island, WA sits at 48.5867° N. The longest day of 2027 here is 16h 08m of daylight on 21 June 2027; the shortest is 8h 17m on 21 December 2027 — a difference of 7h 51m.
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.
