Predict the condition of tides during perigee
WebThe greatest distance between Moon and Earth is 405400 km (Apogee) the shortest distance is 362600 km (Perigee). Perigean Spring Tides occur when Sun, Earth and Moon … A perigean spring tide is a tide that occurs three or four times per year when a perigee (the point nearest Earth reached by the Moon during its 27.3-day elliptic orbit) coincides with a spring tide (when the Sun, the Moon, and Earth are nearly aligned every two weeks). This has a slight but measurable impact on the spring tide, usually adding no more than a couple of inches.
