My Tidelog is for northern California, specifiaclly San Francisco Bay and Delta, south to Monterey and north to the Nehalem River in Oregon. SF Bay is on Lat 38, which is where the Tidelog is most accurate. The days sure seem short to me! It's 9 hrs and 43 minutes long on Dec 22nd.
The tidal range for Dec 22 is about 8.8 feet, compared to a mean range of 5.8 feet at the Golden Gate. High tide of 7.2 ft. is at 10:23 am and low tide of -1.6 ft is at 5:10 pm at the Golden Gate. The further north you go, the greater the tidal range.
Fair winds,

Judy,
Am I right in assuming that the info you quote is for San Francisco?
Sure wish our days were that long in December. Guess that "tilt" hits us
a little harder up here. Just have to keep telling myself we make up for
it in summer. Our sunrise is at 7:56 and sunset at 4:18. The tide change
here (Seattle) is 15.3 ft that day.
