Be prepared for almost anything. The weather can change quickly from warm sunshine to heavy rain. The best way to dress is in layers with plenty of waterproofing. The scenery will more than make up for any poor weather for it is fabulous.
I was on Oriana for a week's cruise last July. We had quite stormy weather going up the North Sea and then in Bergen, our first stop, it was overcast but the sun broke through occasionally. For the rest of the week the weather vastly improved until it became hot and sunny. So yes, take layers, an umbrella, fleece and sun tan lotion!
If the data table works this is the options from July 2008
Temperature: 29.4 °C - 15.4 °C
Dew Point: 17.6 °C - 8.8 °C
Humidity: 98.0% 26.0% 66.1%
Wind Speed: 21.7km/h from the NW - 3.2km/h
Wind Gust: 224.0km/h from the North - -
Wind: - - SSW
Pressure: 1030.4hPa -98.9hPa -
but this year it might reach the max ever recorded or be around the 16/17 degrees !!
Hi Nick, it depends how far north your cruise goes. We had temperatures of 29 degress in Alesund in June last year and -3 in Svalbard. When we went to the North Cape in July it was warm enough to be without coat at midnight but last year in June it snowed! Apparently it rains a lot in Bergen, but we have always had a good day there. Remember that you have to take into account the speed of the ship which adds to the wind chill on deck, so warm, wind proof and water proof is a good idea, just in case - you probably won't need them. Norway is magnificent, I hope you have a wonderful time. Jude.
As said in other replies, be prepared for all weathers.
we did our 1st ever cruise last june to the fjords. we went 8th june.. it was beautiful sailing across the north sea, blue sky and sun.. we even made it into the swimming pool. but when we hit norway it was rain and drizzle most of the time... but with all the rain the waterfall were so great to look at. the cruise that went a few week before norway had very hot and sunny weather... so we will be going back again and maybe we will get lucky and have the sun.
We went to this cruise itinerary (Norway and the North Cape) last July (end June/beginning July) - the weather is unpredicatable ; you can expect everything - when we went to the North Cape it was freezing !!! Very cold indeed!! But in other places such as Tromso, Bergen, Alesund it was a bit cold but fine. You have to be prepared to have thin layers of clothing and a windproof jacket and you will be fine.....what a great cruise .....surely recommended.....will repeat it for sure...such amazing scenery and ambiance.
