Weather in Poland - some explanations

One more question. While my husband says polish weather is the best one in the world ;) with four seasons, beach in the summer, snowboard in the winter and so on, many polish friends I have, said weather in Poland is the worst I can get and they couldn`t see themselves living in that kind of winter anymore. I`ve been in Poland myself few times... winter, spring, summer and autumn but can`t get to a conclusion really...
How is it???

There is not too much sun overall so for a Brazilian it would be difficult to cope, however, an artificial sunlight lamp in the winter should solve the problem:)

Honey if you have lived in the UK then Poland will be wonderful, Ive been in both the winter and the summer...

summer was hot and sunny
winter wasnt too bad it doesnt seem to be as windy as it is here (UK) so its not as "biting" cold and it doesnt rain as much :)

As a brazilian I do enjoy hot sunny weather but not 365 days per year. When I was a child I used to look forward to going to Argentine to enjoy a bit of crispy temperatures. What I`m afraid of is how long is this winter in Poland. Can I say Poland is 50% cold and 50% hot? I don`t mind cold weather, but a short one :)
thanks for the answers guys

It's vary very much from year to year. This year we hardly had any winter but 2 years ago It was very cold and long.

Thank u!! The answers cheered me up a bit ;)
