There’s a legend that it snowed there once in 580 AD.
After the fall of South Vietnam, my wife and I decided to sponsor a Vietnamese refugee family, sort of to pay back the hospitality I'd received over there. We got a man who had been born in the North, then moved South as a refugee after the French lost. He told me that once, as a child, he'd seen snow in the North. Never in the South (I can believe that). Looks like things are really cooling down there.
