When Does Watermelon Season Conclude?

Typically readily available from May to September across much of the U.S., it's no coincidence that watermelons are a staple of the summer season.

As fall arrives, the watermelon season, which is at its height in July and August, usually comes to a close. However, growing seasons can vary depending on the location.

Florida has two primary growing seasons: From March to July, and another from October to December. California has a much shorter harvest period, typically from June to September.

Even if you live in an area where watermelon season tapers off toward the end of summer, grocery stores often sell watermelons even during the fruit's off-season.
