This month had two remarkably cold days: 8.8° on Friday the 8th, just before Queen’s Birthday, and 8.3° on Wednesday the 20th. (Note added: in 2014 these stand as the coldest on the record from 1999.) Nearly all days were cooler than normal. Nights varied, with one above 10 degrees and 10 frosts. The weekly mean temperature was below normal except on the first and last days.
Nine days were completely overcast, and rain fell on 10 days (usually 6) with the highest reading 14.8 mm on the 4th.
The first very cold day was related to a severe “East Coast Low” (990 hPa) that caused widespread damage and major flooding in the Hunter region. Gales and high seas caused the freighter “Pasha Bulker” to run aground.
The mean daily maximum (14.3°) and mean (8.8°) temperatures this month were much lower than in the previous six June months. The daily minimum (3.4°), however, was higher than last year (1.3°). (Note added. The maximum and mean temperatures stand in 2014 as record low values for June.)
The mean daily temperature range this June month (normally 15.0°) was extremely narrow: only 10.9°. (Note added. In September 2014, this stands as a record for any calendar month. The only other months with a mean daily temperature range narrower than 13° were all in late 2010 (expressing that La Niña event): July 2010, 12.3°; August 2010, 11.9°; November 2010, 12.4°; December 2010, 11.8°.)
With 60% of mornings having more than 4 octas of cloud, this was a very cloudy month. (Note added. The only month much more cloudy than this has been June 2013, with 75% cloudy mornings.)
The total rainfall of 65 mm is in the 78th percentile for June (June 2005, with 109 mm, was in the 96th percentile). Rainfall totals for more than one month show no shortages.
Note: Although there were brief reports in the “Manilla Express” dated 10/7/07 and 17/7/07, this report in standard format was written in 2014, with the benefit of hindsight. In particular, it uses normal curves that are based on data for the decade from March 1999 to February 2009.
