Toronto may not experience a return to warm weather until the second week of May, according to meteorologists. The forecast indicates that spring temperatures will remain below seasonal norms for the next several weeks, delaying the arrival of milder conditions.
Extended Cool Spell
Weather experts attribute the prolonged cool spell to a persistent pattern of cold air from the north, which has kept temperatures in the city well below average. Daytime highs are expected to hover in the single digits Celsius for much of this week, with overnight lows dipping near freezing. The trend is likely to continue into early May, with only gradual warming expected.
Residents hoping for an early spring may need to wait a bit longer. The first significant warm-up is not anticipated until at least May 10, when a shift in the jet stream could allow milder air to move into southern Ontario.
Impact on Outdoor Activities
The delayed warmth has implications for outdoor plans, including gardening, sports, and festivals. Gardeners are advised to hold off on planting tender annuals until after mid-May to avoid frost damage. Outdoor events scheduled for early May may face chilly conditions, and organizers are encouraged to monitor forecasts closely.
Despite the cool start, long-range models suggest that May will eventually see a transition to more seasonable weather, with temperatures rising to near 20 degrees Celsius by the third week of the month.
