High tide flooding

The flooding that occurs in the absence of a storm when seawater floods typically dry land due to higher than average high tides, which occur when the moon is new or full (see spring tide); and when the moon and/or sun is closest to earth (see perigean spring tide and proxigean spring tide), and/or during strong onshore winds. High tide flooding is sometimes referred to as “nuisance flooding,” “sunny-day flooding,” “blue-sky flooding,” or “shallow coastal flooding,” but these four latter terms are not recommended for use.
