Norway braces for record-breaking heatwave

Temperatures across southeastern Norway may exceed 30°C this week, with forecasts approaching the national record of 35.6°C set in 1970, according to state meteorologist Pernille Borander of the Norwegian Meteorological Institute.

Borander confirmed that projections of 35°C in the Oslo–Skien corridor put the region “right on the edge of a new record.” Even if the national benchmark stands, local stations are likely to register new highs. Existing regional records include 35.2°C in Akershus (1988) and 35°C in Oslo (1901).

The institute defines a heatwave as five consecutive days at or above 27°C. Current forecasts suggest the threshold will be met, with the hottest conditions concentrated in southeastern Norway. Central and western regions, including Rogaland and Vestland, expect 25–30°C, while Møre og Romsdal and Trøndelag will see 20–25°C. Northern Norway, by contrast, will remain cool and overcast, with temperatures falling from 20°C to 15°C as the week progresses. Svalbard will hover around 5°C under low pressure and northerly winds.

Borander urged residents to prepare for extreme heat, emphasizing hydration, shade breaks, and planning for cooling activities. She noted that while Sunday’s temperatures were lower, the coming week’s sustained heat would be “far from normal.”
