Last 5 May, I called the beginning of the rainy season here in southern Vietnam because the winds had shifted from the east to come out of the west, the monsoon winds that bring the rain for 6 months. On the evening of 10 October, the winds shifted for the first time in a little over five months so they are now out of the east, and have stayed so for the past couple of days.
That doesn't mean the rain will end yet -- the change in winds will bring turbulence for a couple of weeks, but the main season is over, and my mood will improve immensely.
