When you will come here try to keep in your mind that the North Pole is not far :)
Take with you the clothes for cold time. Not more under zero. If it is more...it will be a good ideea to remain in a pub. Even if is not warm it will be a lot of smoke at least...
What is 100% sure is that you will never need a swimming suit...only if you are going to the swiming pool...Yes they have one up here.
Photo Equipment: Do not forget the camera...actually this is all what you need.
Camping/Beach/Outdoor Gear: Fishing trouts in the rivers and lakes aroud is an option... take a fishing line with you. It seems that fishing trouts is open for all the year in Hammerfest.
Miscellaneous: If you like to drink something... bring drinks with you. Even if is the northernmost city....it is still Norway up here.
