The frost-free period is coming to an end

Summer is coming to an end.

Last night (August 10-11), temperatures below freezing were again recorded in southwest Iceland. The lowest temperature was recorded by the weather service at Þingvellir at -1.3°C .

This means that the period without night frost in midsummer this year lasted 27 days .

The last time a night temperature of -0.1°C was measured in Þykkvibær was on July 13th .

For comparison:

In the record summer of 2021 (with high temperatures and little rainfall, especially in the north and east of Iceland), the frost-free period lasted from July 1 to September 6, a remarkable 67 days .

On the other hand, we did see the first northern lights of the season last night, although they were quite faint because it was still relatively light...
