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.
