King Tides and High Tides

Miles of shorelines and waterways, a flat topography, and a shallow water table, make Hollywood vulnerable to the effects of climate change and sea level rise.  Higher than average tides, called King, Spring, or Fall Tides, generally occur when the moon is in closer proximity to the Earth.  King Tides are often the highest of the high and are predicted to coincide with those days when the moon is closest to our planet.  However, rainfall, wind strength, and wind direction can also have a significant impact on tidal heights, causing them to come in higher or lower than predicted.  Storms further exacerbate flooding risks during high tides.  

Below are the higher-than-average tidal events predicted by the National Oceanographic and Atmospheric Administration (NOAA) for 2023.  NOAA predicts King Tides on at least 28 days this year, however, these are predictions, and greater than average tides can occur any time of the year based on various conditions.
