While the costumes might be scary, Halloween weekend weather won’t be — conditions will be warmer than normal, and sunny.

Saturday’s highs will reach the low 60s across Long Island, said Carlie Buccola, a meteorologist with the National Weather Service’s Upton office. That’s a few degrees above the average for this time of year, at 59 for the high and an average of 42 for the low at Long Island MacArthur Airport.

“It’s a nice change from the past few days,” Buccola said.

Clouds are expected to gather overnight with lows around 60 degrees, she said. The clouds will linger Sunday, making for partly sunny conditions. Temperatures Sunday will be even warmer, with highs expected in the mid- to upper 60s.

The chance for rain increases Sunday night into Monday, although Buccola said the rain shouldn’t last long.

“It looks like a quick burst of rain Sunday night,” she said.

Conditions should be clear for Halloween on Monday with slightly cooler temperatures, around the average high for this time of year.

“Halloween on Monday looks good with a mix of sun and clouds,” said News 12 Long Island meteorologist Matt Hammer.

Hammer added that Halloween evening could be chillier, with trick-or-treating temperatures dipping into the 40s.

Long Island’s foliage will also be “near peak” this weekend for those looking to enjoy the warmer weather, according to the state’s I Love NY Fall Foliage Report. Spotters reported seeing 80 percent change in Nassau County, with leaves taking on orange, red and purple hues, though some leaves remain green.

Suffolk County is looking at 70 percent change with leaves at average brilliance. So far, colors appear to include yellow, orange, red, purple and green, the report said.
