Temperature rankings in the Northeast during October. (Southeast Regional Climate Center)

Whether you call it Hotober or Octoaster, the 10th month of the year failed to deliver the standard chill it is known for in the Northeast.

The month ranked as the warmest on record or very close to it throughout the region.

New York City (Central Park), Newark, Hartford, Burlington, Worcester, Portland, Bangor and Caribou all registered their warmest Octobers on record. Boston and Providence came oh so close, ranking second warmest by a fraction of a degree.

Philadelphia and Allentown also just missed posting their warmest October, placing second. Philadelphia’s average temperature of 64.1 degrees was a shade below the record-setting 64.5 degrees set in 2007. Allentown missed its record, also set in 2007, by 0.7 degrees.

Meanwhile, Washington had its third warmest October on record.

The warmer-than-normal air set up in the Northeast due to a semi-persistent area of high pressure that influenced the region

The unusually warm weather took its toll on fall foliage, which was described as duller than normal. Clear, cold nights are deemed optimal for vibrant foliage and, more often than not, it was warm and wet.

The Southeast U.S. wasn’t as warm relative to normal as the Northeast, but most locations still experienced one of their top 10 warmest Octobers.

The abnormally warm October in the Northeast is part of a long-term trend. CBS Boston meteorologist Eric Fisher wrote the Blue Hill Observatory outside Boston, which recorded its warmest October, has now observed its warmest April, July, August, September, October, November, December, spring, summer, fall, winter and year on record since 2010.
