Thursday was the muggiest day ever recorded at St. John’s International Airport, according to numbers from Environment Canada.

The unofficial high temperature in the capital as of 5:30 p.m. was 28.3 C, and the record-shattering dew point (moisture level) hit 23.3, said Jody Boyd, meteorologist with Environment Canada in Gander.

“We broke the all-time high dew point record at St. John’s Airport,” he said. “The previous record was 22.9, which was set yesterday and in 1984.”

Thursday’s humidity was coupled with an unusually high temperature, which was 7.3 degrees higher than the average 21 C on July 25.

“The previous record was 28.3 C set in 1961, so we actually tied the daily high temperature record,” Boyd said.

This weather comes just 10 days after it hit 31.2 C in St. John’s July 15 — the second-highest temperature ever recorded at the airport. Temperatures in Badger soared to 31.3 C that day.

Boyd said today “looks like another warm, sticky day, but there should be some relief in sight for the weekend.”

According to Environment Canada’s website, temperatures in the capital are expected to rise to 27 C today and to 28 C tomorrow.

They are expected to drop to a more familiar 20 C Sunday.

In the meantime, Boyd recommends people limit activity, drink lots of fluid and stay out of the sun.
