Final data aren’t in, but 2010 may be the warmest year on record for Boston
As Boston bid adieu to 2010 yesterday, the dose of unseasonably warm weather seemed appropriate: Preliminary data indicated that the year would be the warmest on record for the area, the Blue Hill Meteorological Observatory said.
By yesterday afternoon, the year was on track to have a yearly temperature average of about 51 degrees, enabling 2010 to break the previous record of 50.9 degrees, set in 1999. .
“It’s pretty incredible,’’ said Sean Fankhauser, a Blue Hill weather observer.
For much of this year, weather watchers at the observatory were expecting a record-breaking year. Every month except December recorded overall average temperatures above normal, while it hit at least 90 degrees on 20 days, according to readings taken atop Great Blue Hill, near the Canton-Milton line.
The first 90-degree day arrived on April 7, 10 days earlier than the previous record in 2002, and the summer proved to be the warmest on record.
Yesterday’s highs reached the upper 40s, a welcome respite for people battling cabin fever after last weekend’s nor’easter.
Temperatures tomorrow are expected to be in the lower 50s
Aside from being warm, 2010 was also wet. The 62.74 inches of rain were the sixth most plentiful ever recorded. But it was not nearly as wet as 1998, when a record 71 inches fell.
The recent storm dumped 18.2 inches of snow on Boston, helping make last month one of the heaviest Decembers on record for snowfall. Snow for the month totaled 22 inches.
The observatory has been recording temperature and precipitation levels since 1885.
The National Weather Service was not quite ready to declare 2010 the warmest on record yesterday, saying it was still compiling statistics. Those data should be released today.
