Every fruit has its season, but in Palestine, where virtually no fruit or vegetable is imported, the seasons are more noticable. You'll be hard-pressed to find citrus in the market in the summer. And you won't find cantelope or figs in the winter. Right now, the oranges and clementines from Jericho are for sale all over Ramallah. If you just want one or two or three, this vendor will give them to you for free.
