What is the weather or temperature in Eastern Europe in July?

pu1. In Poland, the average temperature in July is 12.9 to 23.6 degrees
So I need a coat because it feels quite chilly at night
And it rains a lot, so it's good to bring an umbrella
You can think that you can buy it if you need it, but umbrellas are very expensive
Most of the industrial products are imported, so they are quite expensive

OK

pu2. In July, it is quite hot because it is summer in Eastern Europe
It is similar to Korea because the maximum daytime temperature is over 30 degrees
Just because the humidity is not high, it's not that humid and hot
It's not hot, but the day is long, so it gets dark around 9:30 p.m

pu3. It might be a little chilly in the evening, so I recommend you to take long clothes
