TIPS FOR GDANSK

witam,
I'd like to get my polish boyfriend a surprise trip to Gdansk. (Chcialabym miec niespodzianke do mojego polskiego chlopaka: wycieczka do Gdanska...this is not correct, but a proof of my love;))

would the very beginning of June be recommended, or is it deadly freezing so that we wouldnt be able to take a bath?? Please advise me, it would be just and touch&go visit but I'd like to go to the seaside....
