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

THURSDAY, OCTOBER 8, 2026
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0549E
SUNSET:  1714E

A MIX OF SUN AND CLOUDS; WARMER AND MORE HUMID TODAY….

As the chilly air mass of the past couple of days continues to
push out of the region, clouds along with higher temperatures
and humidity levels have moved in to replace it. Skies have
featured varying amounts of cloudy cover, going from nearly
clear skies to overcast at times. All in all we’re calling it a
mix of sun and clouds.

As mentioned, temperatures are running warmer today with readings
reaching the 70 degree mark by early this afternoon. This is
above normal for this time of year as we should see highs in
the mid 60s. Dew point values, which were in the 30s on Tuesday,
have rebounded to the mid to upper 50s today. As such, you can
certainly feel the increased stickiness to the air.

Winds were gusty overnight, tampered down a bit for a time this
morning, but have become gusty again by late this morning and
afternoon. It gradually shifted from the south-southwest to the
west as the morning progressed. The average speed for the day so
far is around 15mph. The peak gust for the day so far is 33mph
which occurred just after 12:30am this morning.

Visibility has been more limited today thanks to the higher
moisture content. The view early this morning was only around
20-30 miles, but has improved to around 55-65 miles by early
this afternoon.

The maximum temperature so far today is 70F, which is 6 degrees
above the normal high of 64F. The minimum temperature since
midnight is 53F, which is 6 degrees above the normal low of 47F.
