Tropical nights are those that don't get cooler than +20 C over the course of the night.
The warmest night this summer was on June 22, when the temperature in Rīga was +19.6 C, as well as last night – July 17, at 19.3 C in Daugavpils.
In the last 15 years, tropical nights affect some of Latvia almost every summer. Last time when no tropical night was seen anywhere in Latvia was six years ago - in 2017.
The tropical nights record was set in 2021 in Riga, when 19 nights were not cooler than +20 C, including the night of June 23, when the minimum temperature in Rīga was +24 C, the hottest in the history of night weather observations.
Later this week the nights will get colder, and in the second half of the week the temperature will sink to +7 to +12 C. The days also won't be too warm, the maximum temperature on Tuesday will be +19 C to +24 C, and in the remainder of the week +17 C to +23 C.
Rains are expected every day in some parts of Latvia, but rainclouds will be relatively small and drought will continue in many areas.
