As many had feared, the sun-filled rainless summer days would end at some point, and if predictions from the Meteorology and Hydrology Institute are correct, that time is now.
Daytime temperatures are expected to be similar during the next five days, hovering around the 20 C mark until Friday, which could be slightly cooler, reaching as low as 16 C.
Those in the eastern and southeastern parts of the country will be wise to carry an umbrella until Wednesday, after which rain clouds shift west to Pärnu and central Estonia.
The capital and the major islands will be next, with showers predicted to cover the areas from Wednesday evening onwards.
The mini rainy season is set to culminate on Thursday, with weathermen not predicting any dry spots, with only possible lightning to brighten things up.
After Thursday, rainfall is likely to lessen, but even cooler weather arrives on Friday.
Evening and night temperatures will fall to 6 C on Wednesday in central parts of the nation, before beginning to climb again.
