Please excuse the ignorance of this question, but it's time for me to come out of the closet and admit I'm not certain what that last number means under the "Tides" information you see in the newspapers. Example: 1st High 5:15 AM 13.0 1st Low 7:07 AM 8.8 2nd High 2:29 PM 12.2 2nd Low 10:14 PM -3.5 I've made an educated guess that the last number repesents feet above or below some average (or mean) value for sea level, so in the above case would guess the second low tide is a VERY low tide compared to the first. Am I close to right or totally off? I'd like to better understand what I'm looking at when deciding whether and when to head out. :hmmm: Thanks as always.
