It can snow any day of the year, if so. If it snows, it'd melt right the second it touches the ground. The first snow, which definition is 1 cm of snow at 9AM, happens on October 28 on average in Jyväskylä, later in the South.

Normally early October is good outdoors weather with early mornings +0 to +6 degrees and afternoon around +12 to +20 degrees. If it's sunny, it's perfect for spectating rallying, because not being too cold nor too warm. If it rains, it's just as annoying as rain is on any other time of the year.
