I was looking for something like this on our website but embarrassingly we don't appear to have this info on there. Here is a graph from the Florida Gift Fruit Shippers Association of what FL citrus is in season at any given time
http://fgfsa.com/season.htm . Right now you basically have valencias, murcotts (honey tangerines), and grapefruit. If your looking in grocery stores you often don't find alot of FL fruit there because they prefer to carry CA fruit since it is prettier. I can't recall off the top of my head the names of any citrus companies in orlando but that is where the FGFSA is located. I imagine if you called them they could tell you someone nearby that has bagged fruit for sale. If it wasn't a 2 hour drive I'd bring ya some.
oh ya PS valencias are really a juice orange so I would reccomend the honey tangerines or if you can find someone that still has them some temples. Alot of people say temples are their favorite variety even above honeybells.
