This week we’re going to see four days of negative tides during daylight. Negative means that the water drops below the mean lower low tide level, which counts as zero. The extreme low tides lay bare large sections of mudflats in the North Basin cove and often attract the greatest variety of birds. Most of the lowest low tides occur during hours of darkness. Mark your calendar if you want to see them in daylight:
- Thursday March 5, -0.3 at 2:44 PM
- Friday March 6, -0.74 at 3:33 PM
- Saturday March 7, -1.02 at 4:19 PM
- Sunday March 8, -1.09 at 6:02 PM
We’ll also see high tides over 6 feet on Friday at 8:26 AM, Saturday at 9:23 AM, and Sunday at 11:18 AM. Tides at that level flood part of the walking trail along Marina Boulevard and the Virginia Street Extension because the responsible authorities have neglected to repair long-standing gaps in the seawall in those areas.
