One thing is the weather, another thing is the objects in the sky, and another thing is your preferences.
For some objects, you don't have much choice but to put up with mozzies. Conversely for others you need a freezer suit... You can also look to time things around mozzie season, but that is not always practical. This goes for photo and visual.
Winter sees a steadier atmosphere, making high power more productive. Can be clearer too with less dust. But it can be very cold and demanding on batteries. Summer is more comfortable though it has its own set of drawbacks, it can also be very productive.
If mozzies are a concern, you can look for areas where micro bats are prominent. These tiny aviators can be your best friends to control mozzies. The dark site I frequent has hanging swamps all around it, but in 5 years, I've never had a mozzie bite. The bats deal with them fluttering around us all night. Come to think of it, it's like something out of a Batman movie...
You can ask, but in the end you need to bite the bullet, which ever flavour it has.
