Adelaide is feeling the chill and will do so for much of the coming week, potentially giving the city its coldest month in seven years and coldest July in 17 years. Combining overnight and daytime temperatures, the city is averaging 10.8 degrees this month and should maintain that average through to August (the long-term July average is 11.3 degrees). This July has had six cold fronts pass through the city, roughly one every four days, keeping the city colder than average for longer than normal. One of the fronts meant the city only reached 12 degrees (three below the July average) yesterday and then cooled to three degrees (four below average) early this morning. So far today wind has been too light to mix the air, keeping the city below about 12 degrees through to lunchtime. Residents can expect to chill through a few more nights, mornings and days with help from yet another cold front. It should chill below five degrees on one or two more nights this week, taking the monthly tally to eight or nine, about three more than the long-term norm for July. We should also have one or two days where it fails to reach 14 degrees, taking the monthly total to 11 or 12 days, also about three more than the monthly norm. The main factor in this being a colder-than-normal month is three particularly strong fronts in quick succession which held the temperature below 15 degrees for 11 days running, from the 11th to the 21st of July. This was the longest spell this cold since August 2008. August 2008 was also the last time a month had an average temperature of less than 10.8 degrees. The last time a July has been this cold was in 1998, the year the Adelaide Crows last won a premiership and the last time the team's scarves and beanies were as practical.
