When Is Watermelon in Season?
Watermelon season by U.S. region
| Region | Typical window | Source |
|---|---|---|
| Georgia | June–September | UGA Extension |
| Florida | Starts June in the north/central regions, wraps early July | USDA NASS |
| Texas / South-Central | Summer + fall (melons) | ACL regional list |
| California | July–November (melons) | UC ANR |
| New York | September–October | NYS Ag & Markets |
| Midwest (Great Lakes) | Summer (melons) | ACL regional list |
| Pacific Northwest | Fall (melons) | ACL regional list |
Where a source publishes only season-level timing ("summer + fall"), we show exactly that — regional month precision exists only where an extension calendar provides it. Weather moves every window; your market's growers are the final word.
How the season moves across the country
Watermelon is the sharpest illustration of the south-to-north wave on this site: Georgia's four-month June–September run versus New York's two-month September–October window. Florida opens and wraps earliest, the Deep South carries midsummer, and the northern tier's melons ripen just as school starts. That's not a supply-chain quirk — it's growing-degree days.
The national peak for watermelon — like every warm-season market crop — is July–August. See what's in season right now for the current month's full national list, or your state's harvest calendar for local timing.
How to pick watermelon at the market
Texas A&M's picking guide: choose a symmetrical melon with a creamy-yellow ground spot (the patch where it sat ripening in the sun), firm all over, that sounds hollow when thumped. Watermelon is harvested vine-ripe — it won't improve after picking, so the ground spot and the thump are your whole toolkit.
Storing watermelon once you're home
Whole watermelon keeps at room temperature (whole ripe melons hold best around 50°F). Always rinse the rind before cutting — the knife will otherwise carry surface bacteria straight into the flesh — and refrigerate cut watermelon within 2 hours (USDA NIFA).
The storage science, in four rules
- Warm-season vegetables have a chilling-injury danger zone of 45–55°F — cucumbers and summer squash are highly sensitive; snap beans, muskmelon, and tomatoes moderately so (University of Tennessee Extension).
- Commercial growers use a two-cooler rule: 32°F for sweet corn and ripe muskmelon; 50°F for green beans, cucumbers, summer squash, ripe tomatoes, and watermelon.
- Cantaloupe, peaches, and tomatoes produce ethylene as they ripen; snap beans, cucumbers, and summer squash are damaged by it — store the two groups apart.
- Cut, peeled, or cooked produce must be refrigerated within 2 hours, and melon rinds should be rinsed before cutting so the knife doesn't carry surface bacteria into the flesh (USDA NIFA).
Frequently asked questions
When is watermelon in season?
July–August is the national peak. Georgia runs June–September, Florida opens in June and wraps by early July, California melons run July–November — and New York's local window is only September–October. Local timing varies more for watermelon than almost any crop.
How do I pick a ripe watermelon?
Three checks from Texas A&M: symmetrical shape, a creamy-yellow ground spot where it rested in the sun, and a hollow sound when thumped. No ground spot (or a white one) means it was picked early — and watermelon doesn't ripen after harvest.
Why is local watermelon so late in northern states?
Melons need a long stretch of heat. Southern states bank those growing-degree days by early summer; New York doesn't get there until September–October per the state harvest chart. Northern 'summer' watermelon in July is shipped, not local.
Where to buy watermelon in season
The freshest route is direct: find a farmers market near you, browse farm stands and u-pick farms by state, or search by ZIP with the market finder. In-season, direct-from-farm watermelon were usually picked within a day of the table.
