Long Island's summery temperatures Saturday broke a record high set 52 years ago, according to the National Weather Service — but cooler, wet weather is expected to arrive by Sunday morning.

The thermometer hit 83 degrees in Islip, surpassing a previous daily record high set on Oct. 28, 1971, when the mercury reached 75 degrees. 

The average high temperature for the day of the year is 60 degrees.

A cold front moving in later Saturday was expected to bring chillier and more seasonable weather: Temperatures were predicted to drop to 52 degrees Saturday night.

"A cold front approaches from the Great Lakes . . . [Saturday] evening. A wave of low pressure will ride along the front Sunday," the weather service's area forecast said.

Steady rain is expected after 10 a.m. Sunday with a high of about 54 degrees. 

Monday is also expected to be cloudy and soggy with a high of around 63 and a low near 38, the weather service said.

Trick-or-treaters will enjoy a mostly sunny Halloween on Tuesday with temperatures in the low 50s. Nighttime lows will hover at 37 degrees with a 60% chance of showers developing mainly after 2 o'clock early Wednesday morning.

Rain may stick around on Wednesday, with a 60% chance of precipitation, according to the weather service. Daytime temperatures on Wednesday should be near 49 degrees before dropping to 34 at night.

The sun will be out again on Thursday and Friday, with highs of 51 and 57.

Friday's high of 76 in Islip also broke a record set there in 1971, by one degree, the weather service said.
