The weather for this week can be described with one word: hot.

Monday was the summer’s hottest day so far; a record-temperature of 29 degrees Celsius was measured in Luhanka, central Finland.

On Tuesday, it’s likely that similar temperatures become more widespread in most parts of the country with the exception of the north where daytime highs of around 20 degrees are likely.

On Wednesday and Thursday, chances for rain and thunder increase in many parts, but the daytime temperatures are going to stay over 20 degrees Celsius.

Midsummer weather is going to be hot. Temperatures of as much as—or close to— 30 degrees Celsius are possible from Friday through Sunday. In chillier parts, the daytime highs are around 23 degrees and lows drop to 20.
