Blame it on the moon, an asteroid that swooped close to Earth on Friday or an approaching tsunami, but unusually low tides seen across the Vineyard this weekend actually have a simpler explanation than some expected and feared.
The tides this week and through the weekend will be abnormally high and low, due to the nearing new moon phase. The moon was in perigee on Wednesday and is in the new moon phase today.
Mariners beware.
