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

SUNDAY, JULY 28, 2024
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0433E
SUNSET:  1907E

SEASONABLE WITH LIMITED VISIBILITY AND A LIGHT SEA BREEZE IN THE
AFTERNOON….

We observed a lower visibility today due to smoke from the Canadian wildfires,
only observing 20 miles of visibility at most. Skies were mostly cloudy by the
1 P.M. observation, with a light breeze off the ocean to bring the temperature
down slightly. Weather conditions were comfortable outside of the poorer air
quality, with humidity decreasing as the day went on.

Temperatures today are considered seasonable so far!

The maximum temperature so far today is 82F, the same as the
normal high. The minimum temperature since midnight
is 64F, which is the same as the normal low.
