PORTLAND, Maine — August is going down as the 10th straight month with above-normal temperatures in Maine’s largest city.

The National Weather Service says August’s mean temperature in Portland was 69.3 degrees — 2.1 degrees above normal.

The warm August allowed Portland to tie 1988 as the warmest meteorological summer on record. For the three-month stretch from June through August, the city had an average temperature of 68.7 degrees.

That followed the warmest meteorological spring on record.

The last month Portland had below-normal temperatures was last October.
