Where Union is
Union sits at 47.3583° N, 123.0980° W on Puget Sound and the Salish Sea, at Union, WA. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1973 until 1978, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Bremerton, Sinclair Inlet, Port Orchard (NOAA 9445958), 26.3 mi away, and high and low water here run on average about 25 min earlier than there. The nearest weather station is Twanoh - Hood Canal, WA (U of Wash), an offshore buoy reporting wind, waves and water temperature, 4.4 mi away.
The tide at Union
Union has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains noticeably lower than the other. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 11.8 ft, and 7.8 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 1.0 ft and the lower low sits 3.0 ft below the other low. For the water around it: Puget Sound tides are mixed semidiurnal with a strong daily inequality: two highs and two lows a day, ranges of 8 to 14 ft, and lows that differ by several feet.
About this station
- High tide reaches Union about 0.4 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Union from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 11.9 ft above it and mean sea level 7.0 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.8 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Seattle, WA gauge. Source: NOAA CO-OPS station 9445478, established 1973, gauge removed 1978. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Union this month: Nov 25, Nov 26, Nov 27, Nov 28, Nov 29, Nov 30. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
