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

WEDNESDAY, AUGUST 26, 2026
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0503E
SUNSET:  1828E

ANOTHER PLEASANT DAY WITH A MIX OF SUN AND CLOUDS….

The day started with mainly clear skies and very comfortable
temperatures. Much like yesterday, convective clouds of the fair
weather variety developed and has been decorating the sky through
early this afternoon. Some high thin cirrus have also been
advancing into the area from the west. As a result, a mix of sun
and clouds has been the theme today.

Temperatures were on the cool side early this morning with the low
in the upper 50s. They have warmed nicely to around 80F by early
this afternoon. With dew point values around 60F, it hasn’t felt
bad at all out there, quite pleasant for late August standards.

Winds have been on the light and variable side all day. The
average speed for the day so far is only around 7mph. The peak
gust for the day so far occurred back around 3:40am this morning
with a speed of 15mph.

Visibility has been excellent all day with a view of around 70
miles. Pretty exceptional for this time of year.

The maximum temperature so far today is 80F, which is 1 degree
above the normal high of 79F. The minimum temperature since
midnight is 59F, which is 2 degrees below the normal low of 61F.
