The answer is both meteorological and psychological.
Meteorological - Spring and Summer were typically the war seasons, and during those months, rain tends to come during the late afternoon and early evening hours.
Psychological - It's no more likely to rain on a day of battle than on any other day, it only feels more likely. For most people, battles are depressing. They involve immense amounts of death and destruction. Men have had to kill, they have watched their friends die, and they have come close to their own death. Similarly, rain is dark and depressing, so when these two phenomena converge, we notice it, contemplate it, and assign deep meaning to it. This may contribute to the emergence of human sacrifice. Ancient civilizations that relied mainly on rain to irrigate their crops tended to practice ritual human sacrifice, as well (e.g. Mesoamerican Indians, Druids, Phoenicians).

Normal, but on the 3rd battle of Ypres, there was the heaviest rain in 30 years! This slowed the movement of troops. This battle gained 5 miles for the cost of 300,000 lives.
Indra is the God of victory, battle and rain. He is the heroic slayer of the demon Vritra.
You have to go to sootopolis city and battle Juan. He'll give you the rain badge.

It was hail and rain and there was a thunder storm which killed some of William's troops and made others run in terror
both at the same time
In thunder, lightning and in rain. When the hurly-burly's done. When the battle's lost and won.
Change the weather in battle to do that use moves like rain dance or sunny day.
once you battle N in N's castle you will get battle reshiram or zekrom if you have black you will battle reshraim. You also trade celebi to get zorua in Castelia city. If you go to rout 7 you will see a house and a old lady will tell you about tornadus so whenever there is rain you will maby run into tornadus. If you go into giant chasm you will battle kyurem.
