Winter chill-hour tracker: Toronto

Winter chill in Toronto

Chill is counted hour by hour and these are monthly means, so this gives the months that sit in the chill band rather than an hour count. The tracker above gives hours for the completed season.

These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A shaded, sheltered corner holds leaf wetness longer than open ground, so conditions there can favour it more often than the figure suggests. This is a climate profile, not a forecast — the panel above carries the current risk.
