In northern Alaska, far north of the Arctic Circle, the sun never sets in midsummer. The northern lights only come out at night. You can see the problem, right?
Though I laugh about it now, I have to give credit to the guy. He contacted me before making his plans, and I was able to set him straight before he bought some expensive plane tickets and ended up on a very disappointing (and likely mosquito-infested) trip to the arctic.
I realize that’s a dramatic example. It’s not as though endless daylight during the arctic summer is a well-guarded secret. That said, for every location you might visit, there are things about seasonality you should know in advance.
Research your destination
Do your research. Most parts of the world have cold, wet, dry, or hot seasons and the success of your photos could depend on the season you choose. Think of the types of shots you are hoping to make, and then find out what time of year is best suited to those images. Seasonality is pretty intuitive for most photographers. We generally have a good understanding of how spring, summer, fall and winter relate to our photography. But within those seasons things get a bit murkier.
