These sorts of measurements aren't done on the basis of one person eyeballing some pictures or making observations about the weather around them.
If you're serious about trying to understand the world around you, but don't trust others' data analysis, you can download the raw data & do the calculations yourself.
This is a great reply but these people aren't here because they want to learn; they're here the announce that they're better than you, and know The Truth. So, a person like this will take your tide data and just tell you it's false, or flawed, or ask with a wink whether you really can trust it, etc etc. They're not here for conversation, they're here for a monologue.
I check the data for myself, not interested in either a monologue or your soapbox preaching. Review recent photographs of beaches from around the world from today then compare to historic photos of the same beaches.
