Mystery of the “high-high”
And why I love the low-lows

Tides are highly predictable …

But also confusing on Naples Beach, Florida.

A glimpse into the tidal mayhem

The reason: Blame the moon and sun and the position of the shoreline. The tidal cycle is semi diurnal – giving us 2 high tides and two low tides per day. But sometimes the highs are really high (i.e. high-highs) and the lows are really low (i.e. low-lows) and other times the lows and highs are in between (i.e. low-highs and high-lows) which look like a camel’s back (see above). In a nutshell, I still can’t figure it out other than tides are higher and lower during full and new moons. Even more confusing than the tides is the longshore current. Unlike where I grew up in Maryland where the longshore current always flowed south, on Naples Beach it reverses from one day to the next.

My personal favorite: A low-low. I love walking in the tidal pools and the hard flat sand feels good on my feet.
