Hello Carole - you are going to a lovely part of the world on your cruise and at the right time of year too - twenty-four hour daylight whilst you are in the Arctic Circle. Like many such places Norway has very unpredictable weather, and whilst you may be fortunate enough to have sun at the North Cape it will be cold, so do take a warm coat, hat, scarf and gloves plus socks and outdoor shoes. This gear is particularly necessary on deck when you are out experiencing the midnight sun - it's usually freezing! Enjoy your cruise; hope the weather is kind to you. Regards - Janet.
