‘Spring tide’ bringing on extreme high and low tides

The water is far from where it normally is along the shore.

If you’ve gone to the beach within the past few days, you may have noticed something strange — the water is far from where it normally is along the shore.

These periods of extremely low tide is because of a yearly phenomenon known as the spring tide, which happens after a new or full moon. This means that high tides are a little higher and low tides are lower than average.

Dr. Jason Biggs, an associate professor at the University of Guam’s Marine Lab, gave some insight about this natural occurrence.

“When the moon is pulling equally and together with the sun, you have the biggest tidal changes. You have the highest of the high tides and the lowest of the low tides as long as they’re during a full moon or a new moon. It just so happens that we’re closer to the sun in our orbit at this time of the year, so the sun pulls a little harder at this time of the year,” Biggs said.

According to the National Ocean Service, the term “spring tide” has nothing to do with the season, but from the concept of the tide “springing forth.”
