Temperatures on Thursday, September 25th, soared to record levels for this time of the year in Montana, Wyoming, western North Dakota, and the south-central Canadian Plains. Here are a few details.

After a relatively cool summer, an early fall heat wave engulfed the U.S. and Canadian High Plains on Thursday sending temperatures close to 100°F in North Dakota and Montana.

In Canada, Esteven, Saskatchewan hit 34.3°C (93.7°F) and Brandon, Manitoba 34.0°C (93.2°F). Both sites are near 50°N latitude so it goes without saying that these were the warmest temperatures ever observed for so late in the year at those sites. Jonathan Erdman at The Weather Channel pointed out that these temperatures were actually warmer than any location in Texas (93°F/33.9°C at Cotulla) for September 25th. Regina, the capital of Saskatchewan reached 33.1°C (91.6°F). Amazingly, this was the hottest temperature measured so far this year in the city! UPDATE: The 90°F (32.2°C) isotherm pushed as far north as Swan River, Manitoba (52° 07’ N) where on Friday, September 26th 35.1° (95.1°F) was observed. This may be the hottest temperature ever measured so far north so late in the year on the North American continent. The average high temperature for Swan River on September 26th is 60°F.

Jakarta, Indonesia Observes its Hottest Temperature on Record

While on the topic of heat records, it is worth noting that Maximiliano Herrera has informed me that Jakarta, Indonesia’s largest city, measured a temperature of 37.0°C (98.6°F) on September 24th at the Jakarta Observatory. This is the hottest temperature ever recorded at this site and ties the record from any of the city’s various other official weather stations (for any date of the year).
