What is the climatic requirement for flowering in Mango?

Mango flowering occurs during the coolest months of the year.  Flowering requires 4–6 weeks of shoot dormancy and cool night temperatures to trigger floral induction of the terminal buds. The absolute temperature needed for floral induction varies among varieties and climates, but night temperatures between 8°C and 15°C (46–59°F) with day temperatures around 20°C (68°F) are typically needed. Better flowering is seen in trees growing in the subtropics where the seasonal temperature differences are stronger and more reliable than in the hot tropics. In Hawaii, the main flowering is between December and April.
