We did the same cruise last year,and did not take any really warm clothes WHAT A MISTAKE !!!!!
We had to buy a fleece each plus a jumper or two,the variation in temp is quite dramatic from day to day or even hour to hour,also it tends to rain without warning
hope this is a bit of help

Having recently returned from a superb cruise to Norway and Iceland aboard Fred Olsen's Braemar I would suggest a Range of Clothes for our Spring and early Summer, including Rain and Windproof a Hat and Gloves. Weather is cool ,can be sunny but be prepared for rapid changes, high of 15deg C. Good shoes are essential. Evening wear as suggested.
Have a great holiday...we did.
Pretty much what you would normally wear at this time of the year in the UK!
We have often found Norway in summer to be quite hot and worn shorts and T shirts but there can be coller days so its wise to pack a fleece.
For trips to the geysers in Iceland its probably wise to take some old shoes: you tend to return with copious amounts of clay encaked on them!
Be prepared for anything...we went on the Cunard liner Caronia just before it was sold to Iceland and the Arctic. Most of the trip was quite comfortable. Cruising the fjord on the north side of Iceland before arriving in Akureyri, it got very cold and you needed a jacket to sit on deck and enjoy the views. But, up inside the Arctic Circle, in Tromsoe, Norway, we were actually sunbathing on deck on an extremely warm day. This trip was in early August.
Just returned from P&O fire and ice cruise in late June. The weather was much better than we expected 17C in Iceland- we didn't wear any of the warm clothes we took, make sure you have a light weight water proof jacket, wear layers that can be removed easily. Check the 5 day weather forcast for Iceland on the internet before you go - its pretty acurate.
