BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA

SUNDAY, NOVEMBER 9, 2025
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0628E
SUNSET:  1628E

SOME FILTERED SUNSHINE THROUGH MAINLY CLOUDY SKIES, STILL ON
THE MILD SIDE….

Clouds have been the theme today as we await the arrival of
our next clipper/frontal system. Some filtered sunshine has
been observed today which has helped temperatures to warm
above normal. All in all it hasn’t been a bad day at all
through early this afternoon.

As mentioned, temperatures are above normal once again today
with readings reaching the low 60s. This is nearly 10 degrees
above where it should be for this date in November. Dew points
remain on the higher side as well with values holding in the
mid to upper 40s.

Winds have been fairly steady, but generally on the lighter
side. It has gradually veered from the north overnight to
the south-southeast by early this afternoon. The average speed
for the day so far is around 9mph. The peak gust so far today
is 21mph, which occurred around 1:20pm this afternoon.

Visibility has been limited today, first due to thin fog early
this morning, and then general haziness through early this
afternoon.

The maximum temperature so far today is 62F degrees, which is
10 degrees above the normal high of 52F. The minimum temperature
since midnight is 46F degrees, which is 10 degrees above the
normal low of 36F.
