...JACKSONVILLE FLORIDA (JAX) CLIMATE SUMMARY FOR JANUARY 2025...

Jacksonville Florida (JAX) was much colder and wetter than normal
during the month of January 2025. A series of strong cold fronts
pushed through the region producing a long period of colder than
normal temperatures for most of the month. A few of these fronts
stalled near the Jacksonville area during the middle of the month
which produced locally heavy rainfall. The coldest air of the
winter season arrived during the third week of the month and was
followed by a low pressure system tracking from the Gulf which
produced the first measurable frozen precipitation in the local
area since December of 1989. The end of the month finished with a
burst of warm temperatures reaching into the 80s for the first
time since late November 2024.

Temperature data...

The average temperature for January was 48.4F (-5.8F below normal)
and was the 7th coldest month on record at the current Int`l
airport location (since 1971) and the 9th coldest all-time (since
records began in 1871). There was one daily record low maximum
temperature of only 34F on January 22, which was the 11th coldest
daytime maximum temperature of all-time and the coldest since
12-23-1989. The diurnal temperature range on this date was only 3
degrees from a High of 34F and a Low of 31F, which was tied for
the 3rd lowest on record for the month of January. The wind chill
temperature fell to 19F on January 22 as well.

There were 12 days with low temperatures of 32F or less, which
was 6 days above normal. This was the highest number of freeze
events for the month since January 2018. Despite the long duration
of below normal temperatures, there was only one hard freeze on
the morning of January 25, then the Low fell to 26F, which was the
first hard freeze since December 2022.

The temperature remained below 40F for 42 consecutive hours from
530 pm on January 21 through 1130 am on January 23, which ranked
as the 5th longest stretch on record at the current Int`l airport
location. The temperature remained below 50F for 111 consecutive
hours from 10 pm on January 19 through 1 pm on January 24, which
ranked as the 7th longest stretch on record at the current Int`l
airport location.

A strong cold frontal passage on January 6 dropped the temperature
43 degrees in only 15 hours from a High of 75F at 4 pm to a Low
of 32F at 7 am on January 7, which ranked as the 9th largest drop
in less than 24 hours for the month of January.

The temperature rebound of 51 degrees in nine days from a High of
only 34F on January 22 to a High of 85F on January 31 is only
rivaled from a rebound of 53 degrees in ten days from a High of
30F on 1-21-1985 to a High of 83F on 1-31-1985.
