08Editor's notes
What the numbers don't tell you
September is one of the best months, with warm days around 22 °C, cooler nights and the Film Festival in the first two weeks, when stars, premieres and hotel surcharges descend on King Street. After Labour Day the beaches empty and the CNE closes. It is the last reliable patio month. Rain falls on about nine days. The Blue Jays' season ends with playoff hopes in a good year.
Nuit Blanche falls on a Saturday in late September or October. The Word on the Street book festival fills Queen's Park. Hotel rates fall after the Film Festival. Daylight shrinks from thirteen hours to under twelve. For fall colour, Thanksgiving and Nuit Blanche, see October.
