Hot
It is hot from May through September every year. That means 90's during
the day, 80's at night, with high humidity all the time. An afternoon thunderstorm is a blessing that cools things down
for an hour or so. It's a good thing we have air conditioning.
November through March is cooler. Sixties or seventies during the
day dropping into the forties or fifties at night.
Eight or ten nights a year the
temperature drops below freezing. Every few years it stays below
freezing long enough (5 hrs) to damage unprotected plumbing. That's called a
"hard freeze." Once every ten years it snows. It snowed on
Christmas Day 2004. Then it snowed on December 11, 2009.
April and October are glorious.
It rains about 60 inches a year. This keeps New Orleans in the top ten nationwide. Rainfall is distributed pretty much year round. A dry month is considered a drought. Heavy spring rains sometimes cause street flooding. 1978, 1979, and 1995 saw house flooding caused by heavy rains.
Every twenty years or so a major hurricane passes close enough to the city to cause some major destruction. It usually happens in
August or September although the Weather Guys say hurricane season runs
from June to November. Tropical storms, minimal hurricanes and anxious near misses by big storms are annual events.
