BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA
TUESDAY, JUNE 21, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0407E
SUNSET: 1925E
PLEASANTLY WARM AND DRY AGAIN TODAY UNDER PARTLY SUNNY SKIES….
Although today is the summer solstice, mother nature has
chosen to keep the fine spring-like weather going here
across the region today. More clouds around today than
yesterday, but still plenty enough sunshine to generate
another stellar day here on the hill.
The temperature has warmed into the mid-upper 70s yet again.
To add to the comfort, the dew point has remained in the
low 50s. We just can’t beat this as we move into the last
3rd of June!
The wind has been light today with varying directions. The
average speed for the day is only around 7mph. The peak
gust so far today occurred way back after midnight with a
value of only 18mph.
Visibility has been limited all day due to haziness, ranging
between 40-50 miles.
The high so far today is 77F, which is equal to the normal
maximum of 77F. The low since midnight is 54F, which is 6
degrees below the normal minimum of 60F.
