A waterspout formed Saturday afternoon about 7 miles north of Heeia-Kea pier, prompting a special marine warning from the National Weather Service. 

The waterspout was seen as a high temperature of 90 degrees in Honolulu Saturday tied the record for the date set in 1981, the National Weather Service said.

It’s the fifth high temperature record tied this month at the Honolulu Airport and the hot weather is expected to continue into next week.

Forecasters predict high temperatures on Oahu from 85 to 90 degrees through Thursday, with variable winds up to 15 mph, partly cloudy skies and isolated showers.

The tradewinds are expected to weaken, and low clouds and showers will favor the interior and leeward sections each afternoon and evening, with some clouds and showers over windward and mauka sections mainly at night and during the morning, the weather service said. The atmosphere remains stable and heavy rain is not expected, but some moisture moving over the state may bring a higher chance of afternoon showers Monday.

On Wednesday, record rainfall of 0.11 inch set a record for the date in Honolulu, more than doubling the previous record of 0.05 inch set in 1997.

South shores should see wave heights of 3 to 5 feet; west shores, 1 to 3 feet; north shores, 2 feet or less; and east shores, 2 to 4 feet on Sunday.

Small, south-southwest swells should continue through Friday, with a small northwest swell expected late next week.
