After the great summer we’ve had, get ready for “nature’s bonus.”

That’s how David Phillips, senior climatologist with Environment Canada, describes the season when leaves turn fiery red, deep burgundy, orange and burnt sienna.

With the first full day of autumn arriving tomorrow, there is nothing to suggest anything but “a spectacular” viewing season in the coming weeks, Phillips said.

The conditions this summer have laid the groundwork for an ideal season, which should peak in southern Ontario just after Thanksgiving Day (Oct. 11). All summer, we’ve had lots of sunshine and an ample supply of rain.

“The trees are in great shape and showing no distress,” said Phillips. “If there’s been drought, leaves will turn brown and fall early. Trees don’t even like smog, so this has been a perfect season for them.”

The warm temperatures all summer have warmed the Great Lakes, meaning the colour change season will be a little bit delayed this year. Though the long-range forecast suggests we might see a touch of frost, it won’t be a killing frost that can lay bare all the glorious colours.
