THUNDER BAY — For the second straight month, Thunder Bay experienced unusually warm and dry weather in August.
Environment Canada data released Monday shows that the mean temperature for the month is 19.2 C, well above the long-term average of 16.6 C.
The mean temperature is calculated by adding the high and low temperatures each day and dividing them in half.
It shows that August was marked by both warm nights and warm days.
Meteorologist Peter Kimbell said it was among the top five warmest Augusts ever recorded by monitoring equipment at Thunder Bay Airport, and the warmest since 1983.
That was the year that the city recorded its hottest-ever day. The thermometer reached 40.3 C or 104.5 F on Aug. 7.
This year, new daily all-time high-temperature records were recorded both on Aug. 15 and Aug. 18.
Only 42 millimetre of rain fell at the airport in August, only half the normal amount.
However it was not nearly as dry as July, when the rainfall of about 16 millimetres was only 18 per cent of what Thunder Bay usually gets.
