Spring in Boise arrives with two things that land directly on glass: cottonwood fluff off the river corridor and a heavy tree-pollen load through April and May. Add the irrigation canals coming back online mid-April and you get the messiest window month of the year, which is also the worst month to clean early.
The cottonwoods along the Boise River and the Greenbelt release for a few weeks in late spring, and the fluff sticks to anything with static or moisture on it. Cleaning glass at the front of that release means cleaning it again. The practical move in Boise is to let the drop finish, then clean once, rather than paying twice for the same windows three weeks apart.
Tree pollen in the valley does not sit loose on glass the way dust does. Once it gets damp overnight it bonds into a yellow-green film that a garden hose smears rather than removes. That film is one of the clearer cases for pure deionized water, which lifts it and rinses without leaving soap residue for the next round of pollen to stick to.
Irrigation across the valley comes back on around mid-April. The first few weeks are when misaimed heads show themselves, because nobody has watched the system run since October. Walking the yard during a cycle in late April and re-aiming anything hitting glass will save more window cleaning over the summer than any product will.
Spring is the right time for gutters, because the winter's worth of needles and grit is sitting in them and the spring rain has to go somewhere. It is also the right time to catch what winter did to the house: north-facing algae, salt splash at the base of the siding, and anything the freeze-thaw loosened.

After the cottonwood release finishes and the heaviest tree pollen has passed, generally late May. Cleaning before that usually means paying for the same windows twice.
Not always, but once pollen has been rained on and dried it forms a bonded film rather than loose dust. That is when a hose makes it worse and pure water makes the difference.
Both if the house sits under trees, but spring is non-negotiable in Boise because winter debris is already packed in and spring rain needs the path clear.
