Crescent Moon and High Tide on Wednesday, September 16
The Highest Tide for September (a not-very-high +6.2 feet), is predicted for 8:10 p.m. on Wednesday, the 16th. The month's lowest tides (a not-very-low minus 0.6 feet) will occur on the mornings of the 16th and 17th at 2:04 a.m. and 2:39 a.m., respectively. During September the tidal range is typically minimized. Starting in mid-October, strongly negative tides will begin to occur during the afternoon hours (a much more convenient time for exploring tidepools in the low-lying intertidal zone), and not much in the early morning. By December the highest high tides will crest at about +7 feet and the lowest low tides will sink to nearly -2 feet.
The Waning Crescent Moon and the brilliant planet Venus encounter each other at close range in the eastern sky during morning twilight on Wednesday, September 16. Only about 3 degrees of angle will separate the moon from Venus, though Venus (of course) is vastly farther away in space than the moon is.
