While record-breaking heat enveloped the Pacific Northwest in June 2021, other parts of the Northern Hemisphere also saw early-summer temperatures climb.
While record-breaking heat scorched the Pacific Northwest in June 2021, parts of Europe and Siberia also saw early-summer temperatures climb.
The heatwaves are apparent in this map, which shows anomalies in air temperature at the surface from June 18-25, 2021. The anomalies indicate how much the daytime temperatures were above or below the average for the same period between 2003-2013. Red areas depict where the temperature was hotter than usual, and blue areas were cooler than usual. Data for the map are from the Atmospheric Infrared Sounder (AIRS) on NASA’s Aqua satellite.
One of the hot spots parked over central and eastern Europe. On June 23, ground stations in Moscow measured an air temperature of 34.8°C (94.6°F)—the city’s hottest June temperature on record. Helsinki, Finland, also saw its hottest June day on record (31.7°C/89.1°F), and national records for the month were set in Belarus (35.7°C/96.3°F) and Estonia (34.6°C/94.3°F).
