It rained in Jaipur today. Nikhat says this means Jaipur's climate has now become rainy, since it…

Why

Nikhat has noticed something real — it genuinely did rain in Jaipur today, that's not in question. Where the reasoning slips is treating one day's conditions as if they describe the PLACE permanently. Weather is what the sky is doing right now or today — temperature, rain, wind, all of it can change from morning to evening. Climate is the pattern of weather a place typically has over many years, built from thousands of days added together, not from any single one. Jaipur's climate is hot and mostly dry precisely because most of its days, over many years, look that way — one rainy day doesn't outweigh that pattern any more than one cold day in summer would prove winter had arrived. Test: Chennai can have a rainy December day and a dry one the very next day — its weather changes daily, but its climate (as a coastal, seasonally rainy region) stays the same over years. No, one day is weather, not climate: climate is the long-run pattern built from many years of days, and a single day's rain doesn't rewrite it.
