2008 was a cloudy year of cooler than normal temperatures and reasonably good rainfall. Fine sunny conditions prevailed on 154 days which was well below the long term average (LTA).

RAINFALL:After a wet start to the year the autumn and winter months were drier than normal, but were followed by a wet spring and close to average rain in December. The wettest months were February with 173.8 mm and November with 124.2 mm. The driest month was March recording only 4.8 mm which was the lowest for that month for 43 years. The most noteworthy rain event of the year was on February 12th when 50 mm of rain fell throughout the day causing major flooding in Dumaresq Creek. The total for the year of 766.8 mm was 20 mm lower than the annual average. ††

TEMPERATURES:The year started off with an unusually cool summer, autumnís temperatures were closer to normal, and June was unusually mild. The coldest winter weather started in early July and lasted almost eight weeks until the last week of August. As spring arrived temperatures became warmer than normal during September and October, but cooled down a little in November. Decemberís temperatures were close to normal. Overnight temperatures were notably cooler than normal in March, May and August, but were close to normal in all other months. The hottest day of the year was January 13th at 29.5 degrees. It was highly unusual that the temperature did not reach 30 degrees during the year. The lowest overnight temperature was -9.0 degrees on July 12th. The coldest day was July 9th with a maximum of just 5.0 degrees along with light snow falls.

EVAPORATION:Total for the year was 1,012.8 millimetres which was 204 mm less than the LTA. This was the lowest yearly total on record for the 26 years since recordings began. The previous lowest was 1,054.2 mm in 1999. This is a significant departure from the normal. Factors contributing to this low amount include the unusually cool summer months at the beginning of the year, and the higher than normal number of cloudy days throughout the year.

FOGS:There were fogs on 22 days which is 10 days less than the annual average. The foggiest month was May with fogs on 5 days. All fogs were in the early mornings with none in the evenings.††††

SNOW: Snow fell on two days. In the evening of May 17th it snowed from 10.30 to 11.10pm settling on the ground to give a patchy white cover, but melted in the early hours of the following morning. On July 9th there were light snow showers throughout the day with the best fall from 2.25 to 2.50pm when large flakes settled on the ground to give a thin white cover which melted soon after. The annual average is 2.3 days of snow.
