Someone forgot to pull the plug on summer.
Want a weather record for Sunday? You can pick your favourite because we broke a lot of them at once, the way Wayne Gretzky used to. Here’s a sampling:• Hottest Sept. 24. It reached 31.4 C at 3 p.m. The old heat record for Sunday’s date was 28.5 back in 2010, but Ottawa burned through that around lunchtime.
For context, the average high for Sunday’s date is 17.7 C.• We just had our 13th day in a row with a temperature of at least 25 C. That’s another first. A tip to weather historian Rolf Campbell who worked out that one.
