Today is August 29th. It's the 242nd day of the year. 124 days remain. It's week 35 of the year.
Unless noted, the following data is based upon observations
collected by the National Weather Service, Chicago, at O'Hare
International Airport (ORD) between November 1978 and last year. ORD
has been the official site of record for Chicago since Thursday,
January 17, 1980. Before
this, the official site of record was on the
south side of Chicago at Midway
International Airport (MDW), beginning on Wednesday,
July 1, 1942. From Friday, January 1, 1926 through Tuesday, June 30, 1942, the official site was at the University of Chicago. Before that, the official site was
at various locations in Chicago going back to
Monday, October 16, 1871. Observations taken from
October 15, 1870 to October 8, 1871 were lost in
the Great Chicago Fire.
According to the National Climatic Data Center (NCDC), the normal
high is 80 and the normal low is 61. I've calculated the 33-year
averages at 81 and 61.
On the hot side, the following four days are tied as O'Hare's warmest August 29ths: 1973 (high of 92 with a low of 73), 1984 (high of 94 with a low of 71), 1991
(high of 92 with a low of 73), and two years ago, in 2010 (high of 94
with a low of 71). The other warm highs were 94 degrees in 1983, 92 degrees in 1962 and 92 degrees in 1980.
The highs of 94 degrees are O'Hare's hottest of the date. The other warm low of 73 degrees occurred in 1995. The lows of 73 degrees are O'Hare's warmest lows of the date. The record high of
98 was set in 1953. The record warmest low of 74 was set in 1973. Both records were set at Midway. 26 of the past 33
highs (79%) were in the: 70s (11) and 80s (15). O'Hare recorded 12 consecutive years of highs in the 70s
and 80s from 1992 through 2003.
Five highs (15%) were in the hot 90s. Two highs (6%) were in the cool 60s (69 degrees three years ago (in 2009)
and 69 degrees in 2004.
In looking back through the years to the first August at O'Hare in
1959, the following instances were notable: In 1973 the high was 92
with a low of 73, a hot day. 1973 was the year of the record warmest
low. In
1971 the high was 84 with a low of 53, a 31 degree spread. In 1965 the
high was 66 with a low of 41, a cool day. That low of 41 was colder
than the record low. In 1964 the high was 83 with a low of 52, a 31
degree spread. In 1962 the high was a hot 92 with a low of 59, a 33
degree spread. In 1959 the temperatures for today (the 29th) and
tomorrow (the 30th) were the same: a high of 86 with a low of 69.
More recently, there was a large spread of 30 degrees in 1983 (high of 94, low of 64).
On the cool side, in 1982
the high was 72 with the co-record low of 43. That record low of 43 degrees was
first set in 1965 at Midway. In 1986 the high was 71 with a low of 44. 1982 and 1986 are O'Hare's co-second coolest August 29ths. The other cold low was 48 degrees in 1988. As
you can see, those 40s lows occurred quite some time ago in the 1980s, from 1982
through 1988. The record coolest high of 62 degrees occurred way back in 1893, at a time when the official readings were taken adjacent to Lake Michigan. 25
of the last 33 lows (76%) were in the: 50s (10) and 60s (15). O'Hare recorded nine consecutive 50s and 60s lows from 2001 through 2009. Three
lows (9%) were in the cold 40s. Five lows (15%) were in the warm 70s. O'Hare's coolest August 29th was in 1965 as the high was 66 (O'Hare's coolest high of the date) with a low of 41 (a low colder than the record low and O'Hare's coldest low of the date).
