We have lived here for the last 2 years and have found February to be the worst month weather wise. It is usually very cold, it can be very wet sometimes for days at a time. You will need to bring jumpers, stout shoes or boots if you are going out, and warm jackets/coats. An umbrella will be usefull as well, better safe than sorry. Some days can be sunny, but there is not a lot of warmth in the sun and then when the sun does go down you feel the cold more. Make sure that if you do book in a hotel/apartment that they have either duvets or blankets as you will need them. Good luck with your house purchase.
