Winter Orange Season

The winter orange season in California is a much-anticipated time of the year, typically spanning from December through April. It is during this period that the state’s famous Navel oranges make their grand entrance. Winter oranges are characterized by their bright, seedless, and easily peelable fruit, and they have a remarkable sweetness that sets them apart. The cooler temperatures and occasional seasonal rainfall during the winter months contribute to the exceptional quality of these oranges. As temperatures drop, the sugars within the fruit concentrate, resulting in the sweet and juicy flavor that Navel oranges are known for.

Summer Orange Season

The summer orange season in California is a contrasting yet equally delightful chapter of the citrus story. Typically stretching from May to October, the summer season is when late-season varieties come to fruition. Among them, the beloved Valencia oranges take the stage. These oranges are known for their juiciness and versatility, making them perfect for fresh-squeezed orange juice or snacking. The warm and dry summer climate in California is well-suited for the late-season oranges to thrive. The longer and sunnier days provide the ideal environment for these oranges to ripen to perfection, ensuring that consumers can enjoy their refreshing and tangy flavor throughout the summer months. The combination of summer sun and a Mediterranean climate makes this season a time of citrus bliss in the Golden State.
