June 2012 will go into the record books as the hottest June since record-keeping began in Denver in 1872.<\/figcaption><\/figure>\n

You didn\u2019t need a thermometer to know that June 2012 was extraordinarily hot.\u00a0 What is normally one of the most pleasant months in Thornton turned into a scorcher with high temperature records seemingly falling daily.<\/p>\n

The first half of the month was unseasonably warm but that was only a warm-up (pun intended) for what would come during the latter half of the month.<\/p>\n

Officially for Denver nine daily high temperature records were tied or broken.\u00a0 The first record fell on June 4th and then the records on the 9th, 17th, 18th, 22nd, 23rd, 24th, 25th and 26th followed suit.<\/p>\n

The temperature at Denver International Airport hit 100 degrees or higher six times during the month \u2013 the most ever recorded in June.\u00a0 Five of those 100 degree days were consecutive from the 22nd to the 26th and all of those dates set records.\u00a0 On 17 of the 30 days of the month the temperature reached 90 degrees or higher.<\/p>\n

In the end Denver saw an average monthly temperature of 75.0 degrees.\u00a0 This was an astonishing 7.6 degrees above normal and puts June 2012 in the books as the hottest on record.<\/p>\n

Thornton, while not quite as warm as DIA, still saw an extraordinarily hot month.\u00a0 We recorded 16 days of 90 degree or higher temperatures, one shy of Denver.<\/p>\n

From the time ThorntonWeather.com was founded in October 2006 until the start of June 2012, we had only twice before recorded temperatures of 100 degrees or higher.\u00a0 We doubled that tally in June alone as on four days we reached 100 degrees or higher.<\/p>\n

Thornton recorded an average monthly temperature of 73.9 degrees.\u00a0 This was 6.7 degrees above the average of the previous five Junes.<\/p>\n

In terms of precipitation, Denver officially recorded 1.22 inches of precipitation which was 0.76 inches below normal.\u00a0 All of that was recorded on the 6th and 7th when thunderstorms rolled through the airport area.<\/p>\n

Here in Thornton we didn\u2019t benefit from the thunderstorms nearly as well.\u00a0 A mere 0.11 inch of precipitation fell into our rain bucket, far below the 1.44 average of the past six years.<\/p>\n

…JUNE 2012…HOTTEST JUNE ON RECORD…<\/p>\n

June 2012 was the hottest June in Denver since weather records began back in 1872. The month got off to a warm start with above normal temperatures during the first 9 days of the month. Record maximum temperatures were set and tied on the 4th and 9th respectively. An upper level trough of low pressure which moved across the northern and central Rockies brought cooler temperatures to the region… Resulting in below normal temperatures on the 10th and 11th. Upper level high pressure then reestablished over the region bringing another stretch of above normal temperatures from the 12th through the 19th. Record high temperatures were set both on the 17th and 18th. An upper level trough of low pressure and associated cold front brought some relief to Colorado on the 20th. The high temperature on the 20th was a pleasant 76 degrees…which was eight degrees below normal. Much above normal temperatures returned to Denver the final 10 days of the month as a strong upper ridge of high pressure built over the desert southwest and migrated into the central plains states. A stretch of 5 consecutive 100 degree days occurred from the 22nd through the 26th. This was only the third time in Denver weather history in which this has happened. The other occurrences were July 4th-8th 1989 and July 19th-23rd 2005. In addition…each of the 5 days set new record high temperatures. The 105 degree readings on the 25th and 26th established a new all time record maximum temperature for the month of June and tied Denver’s all time annual record high temperature.<\/p>\n

Temperatures:<\/p>\n

The average temperature for the month was 75.0 degrees which was 7.6 degrees above normal. This makes June of 2012 the hottest June on record. There were 17 days in which the maximum temperature exceeded 90 degrees. This ties 2002 for the second most 90 degree days in June. June of 2006 still holds the record with nineteen 90 degree days. There were also six days in which the temperature reached the century mark. This is a new record for 100 degree days in the month of June. The old record was 3 days back in June of 1990. The coldest temperature on the month was 43 degrees which occurred on the morning of the 11th. Below is list of temperature records tied or broken during the month.<\/p>\n
