Hi we live in Texas and sail out of Galveston and other ports (miami, fort lauderdale, etc) often. My biggest advice with sailing from Galveston is plan on spending one night in Houston after the cruise. We always fly in the night before and fly out the day of disembarking. In Galveston we are lucky because we can drive home. Its happened to us twice now...the port was closed due to fog and we couldn't pull in. One time we couldn't get on the ship until 8 or 9pm....i remember it being dark
Fog is an issue in Galveston for just a few months - November to March, if it happens. Also, the pilots who guide the ships into and out of the port have reached an agreement to move the ships when there is some fog, unlike before. I'm afraid your post is a little too much "Chicken Little", the sky is falling, the sky is falling. What occurred in the past is not necessarily what will happen in the future.
