Any time you can get to Iceland is a good time!
But, more helpfully, the most sunlight would probably be in June, with July and even August having sunset at about 10:30-11:00 (which means more like about 18 hours of sunlight!) The weather then is terrific, in the 50s and 60s, and a good chance of sunny days. (It does, I have to admit, get its share of rainy days.) But even those are fun.

Never!!!!!!!!

Iceland in the winter is wonderful. Yes it is cold but inexpensive and not crowded. I loved it! the 101 degree geothermal pools in a snow storm is something you'll never forget. Check out the special bargains with www.icelandair.com for winter get aways. I promise you won't regret it.

We went to Iceland in August and loved it. We had long days and good weather. It only got rainy one day in the south. Not crowded since we made a tour around the island clockwise. Several unforgettable places. It is a surprisingly beautiful island.

If you mean midnight sun, it happens at midsummer.I've heard it also happens in the Shetlands.

Iceland's tourist season is June - August. This is the best weather but the most expensive airfares ($1000 US). However the accomodations are numerous and inexpensive because they have the schools throughout Iceland available for tourists. Also lots of camping is available.

In the shoulder season May, Sept, Oct, the weather is still very nice (mixed sunny and rainy) and the airfare prices drop. However, the schools are in use and it may be too cold and windy to camp. The cheapest airfares are the winter airfares.

The "midnight sun" would only be seen in the far northern part of Iceland (that extends north of the Arctic Circle) on June 22. The rest of the summer in Iceland will have very long days (12 or more hours) throughout the summer months.
Often in the shoulder season and the winter you will be able to see the Northern lights.

Iceland is very beautiful at all times of the year. September, after the prices drop and the tourists leave is nice, but be warned that many Iclanders head to the capital for extended parts of that month to shop. So many "tourist" amenities in the outlying areas are closed.

We were there the first week of May, stopping off on our way back from the Netherlands. The weather was cool (50s F), but not cold. A bit windy sometimes, which made it feel colder. Sometimes sunny, sometimes overcast, but no rain. We really enjoyed it for the three days we were there. Air fare from BWI to Netherlands and back by way of Iceland was a real bargain at that time of year.

We went to Iceland for Thanksgiving week one year -- and it remains my favorite vacation of all time.

The people were wonderful, the landscape was breathtaking, the frozen waterfalls were especially gorgeous, and there were no crowds.

The days were already getting short -- but it didn't turn out to be an issue at all.

We stayed at a hotel, did plenty of car/bus tours to interesting spots and went on many day hikes. There are several wonderful places to see not far from Reykjavik.

If you're an outdoor person or are interested in geology, Iceland's a terrific place to visit.
