The frost advisory that recently impacted Ajax and the surrounding Durham Region has officially ended, as warmer, wetter conditions move into the area. According to Environment Canada, there are no active weather alerts as of May 5, 2026, marking an end to the cold snap that began in late April.
The advisory, which was issued on April 30, warned residents of freezing temperatures that posed a risk to sensitive plants and trees. With the risk now passed, residents who took precautions to cover their gardens or bring potted plants indoors can safely remove those protections.
While the threat of frost has subsided, The Weather Network reports that the region is transitioning into a period of rain. Residents should expect 10 to 15 mm of precipitation over the coming days, with an 80 percent probability of showers starting Tuesday afternoon and continuing through Wednesday. Environment Canada forecasts temperatures to reach 17 degrees Celsius on Tuesday before cooling to 11 degrees Celsius by Thursday, bringing conditions slightly below seasonal norms for early May.
