When Will Tides be Higher Than Normal?

According to NOAA’s high tide bulletin, the region will see higher tides on:

  • March 28 – April 1
  • Apr 26 – April 30
  • May 24 – May 29 (The predicted tides at several locations will be some of the highest of the year)

Why Will Tides be Higher Than Normal?

  • A perigean spring tide will be occurring in December.  This is when the moon is either new or full and closest to earth.  Higher than normal high tides and lower than normal low tides will occur.
  • The increased angle of the sun relative to the Earth, which reaches a maximum during the Winter Solstice (December 21).
