Tides vary on timescales ranging from hours to years due to a number of factors, which determine the lunitidal interval. To make accurate records, tide gauges at fixed stations measure water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called .^[3]
While tides are usually the largest source of short-term sea-level fluctuations, sea levels are alsomean sea level subject to change from thermal expansion, wind, and barometric pressure changes, resulting in storm surges, especially in shallow seas and near coasts.

That's why I used the "mean or average" tide for my comparison.

Over 60 years - should take into account all variances?
