Hawaii expected to see higher than normal tides this week

HONOLULU (HawaiiNewsNow) -

Starting Wednesday, Hawaii will see higher than normal tides, which could lead to minor coastal flooding.

The National Oceanic and Atmospheric Administration said the high tides will last until Saturday.

These dramatic changes happen when the moon is either new or full and closest to the earth, NOAA said. Tides will increase near the June 21 summer solstice due to the sun’s position to the equator.

Some tidal flooding is possible along the coast, especially in low-lying areas. However, storms or large swells could increase flooding impacts and could also cause erosion.

Last year, Hawaii experienced record-breaking high tides – also known as king tides – which swallowed up stretches of beach and virtually put places like Mapunapuna under water.

Scientists say the king tides were caused by a series of factors all stacked up on each other, including normal seasonal high tides, a type of ocean circulation (or what scientists call a mesoscale eddy), a large swell and long-term sea level rise.

Scientists also pointed to what they called the “blob,” an area of warmer and higher seas concentrated around Hawaii, which persisted most of the year last year.
