September was really warm and really wet in Chilliwack as eight temperature records were broken and rainfall was 50 per cent above normal.
The month also signalled the end of the hottest summer on record and the 13th consecutive summer with above average temperatures, according to Environment Canada volunteer weather observer Roger Pannett.
The average temperature between July and August was 19.56 C, which is 2.33 C above normal.
A total of 167.8 millimetres (mm) of rain fell over 17 days last month, compared to the average of 112.7 mm on 11 days.
September was the fifth consecutive month when overnight minimum temperatures were "well above normal," Pannett said.
High minimum records in the 16.2 C to 18.6 C range were broken on Sept. 6, 7, 11 and 12.
On Sept. 11 the mercury hit 33.5 C, a record maximum for the day, which also saw an all-time record average temperature of 26.05 C. Overall, the month was the warmest since 1974.
The month began with an upperlevel low pressure system moving up from the Oregon coast, which resulted in a number of rare thunderstorms in the Fraser Valley.
Mid-month is when the hot weather hit, breaking a number of records.
Then an active Pacific frontal system rolled in Sept. 28, which produced a record rainfall for the day of 42.8 mm, exceeding the previous record from 1961.
To date there have been 1,160 mm of precipitation on 139 days compared to the 30-year average of 1,160.5 mm on 117 days.
