What is the 50-90 rule for tides?

50/90 Rule gives you “… the SPEED OF THE CURRENT at the end of each hour.” Counting from slack, the current will flow at 50% of its maximum speed at the end of the first hour, 90% at the end of the second hour and full 100% or maximum speed at the end of the third hour and then back to zero with the same steps.

Why are sea waves stronger at night?

At night, the atmospheric boundary layer tends to develop a marked temperature inversion, up to over a kilometer high. This acts to curve sound downward. This in turn means that at night you can hear the crossing whistle of a train that is from several kilometers from you.

Why does sea level rise at night?

The sea level rises at night because of the influence of the moon's gravity. While it is not strictly tied to the day-night cycle, the moon's pull changes the distribution of water on Earth, most obviously in our oceans, where tides can rise and fall by several feet at a time.
