Tides and Weather’s impact on fishing solved

Tides and Moon




Tides and weather have the greatest impact on fishing.  The sun and the moon cause tides and to a lesser degree wind.  Tides are mostly impacted by the moon because the moon is much closer to the earth than the sun.   The moon’s illumination is indicated by the red line in the attached chart.  The blue line is the difference between low and high tide in feet.  When the moon is 0% illuminated or black on the 7th day it makes for the largest tides during the lunar cycle.  This is because the moon and the sun are on the same side of the earth during the new moon and working together to influence the tides. A full moon with 100% illumination on the 21st day has less of an impact on tides because the moon is opposite the sun and the sun is negating part of the moon’s effect.  During the new moon phase, tides change by as much as 7 feet while during the full moon tides only change by 4 to 5 feet.  If the wind is blowing from the east high tide will be greater but low tide will be highere than predicted.  The opposite is true if the wind is from the west.  If you are a kayaker check the tide schedule before you go out to take advantage of the tides.  Tides at downtown Fernandina Beach varies from the St. Johns River by as much as 30 minutes in a distance of fewer than 20 miles.  There are eight tide stations between Fernandina Beach and Mayport (St. Johns River).   A good site to check tide is:  Tides4Fishing  or SaltStrong’s SmartFishingTides
