What is the 30-day outlook for London?
The london ontario weather 30 days trend points to a gradual warm-up, with daytime highs climbing from seasonal February norms near 0°C toward 5–8°C by the first week of March. Overnight lows will remain below freezing, ranging from -8°C to -2°C. Precipitation is near normal, with 3–5 days of snow or mixed rain-snow events expected during the period.
How does this compare to seasonal averages?
London’s late-February average high is -1°C and the average low -9°C. The current forecast runs about 2–4°C above normal for the high end, with overnight lows slightly milder than average. Wind chill values will still push into the -10°C to -15°C range early mornings. No widespread freezing rain events are signalled in the next 7 days.
When will snow return in London?
Flurries are possible on Thursday afternoon as a weak trough passes. Accumulations should remain under 2 cm. The longer london ontario weather 30 days loop shows a minor system around March 1–2 that could bring 2–5 cm of snow or a rain-snow mix.
Is a weather warning in effect?
No warnings are posted for London or Middlesex County as of the last update from Environment Canada. Check the current weather warnings page for any late-breaking advisories.
Will next week feel like spring?
Daytime highs in the 5–8°C range for late February will feel mild, but nights stay below freezing so frost and ice remain possible. It is a typical early-spring tease rather than a true season change. For the southern Ontario picture, see the Canada weather hub.
