This is just my wild guess/theory...things grow different depending on the elevation and the temp it provides. Seems (to me) like some stuff is ripe months ahead of time in the eastern part of the island way up in the mountains. If you ask the fruit/veggie vendors they will often tell you "they are not ripe here that is why they cost so much cause they come from XYZ". Actually dem nah sa dat, dem sa a ting or to in Patwa dat means dah same....I might be wrong but I'm almost 100% sure I've consumed fresh pears....avocado at least 6 months out of the year without them being imported.
