Oshawa Monday weather is expected to be sunny, with a daytime high of 18 C and a clear night bringing a low of 5 C, according to Environment and Climate Change Canada.
The federal forecast was issued at 5 a.m. on Monday, October 19. It lists a UV index of 4, or moderate, for the day. No alerts were displayed for Oshawa when the official page was checked after 9 a.m.
Cooler evenings ahead
Tuesday’s outlook calls for sunshine and a high of 17 C, followed by a clear night with a low of minus 1 C. Wednesday is forecast to remain sunny, reaching 15 C before temperatures fall to zero overnight.
These figures come from the current Oshawa-specific federal forecast. They differ from the broader Durham-area morning roundup’s 16 C daytime high, so residents should use the latest forecast for their own community rather than assume one figure applies across the region.
At 9 a.m., the Oshawa Executive Airport observation recorded sunshine and a temperature of 8 C. That is an observed reading, not the forecast daytime maximum. Conditions and forecasts can change; the official page provides updated readings and alerts.
