The Ottawa outdoor window
Late May to mid-September is the reliable stretch. Inside it, the day’s temperature does more to the plan than the menu does. In the shade, dairy and cured meat hold for about two hours; past about 32 °C that drops to about one hour. Cold bases carry the higher-risk items, and the second wave comes out later than it would indoors. Early June and the first half of September give the easiest afternoons, with warm light and temperatures that leave soft cheese alone.
