Advertisement Okay, I'm a northern hemisphere guy who is mucho attuned to the earth and things that grow. So in the hemispheres you have four seasons. Logical progression, Spring, Summer, Fall, Winter. Spring. Rains and getting over the dog of winter. Trees start to bud. Flowers grow. Then a world of green. Summer. Dries up. Hot. Arid. Growing season over. Fall. Trees lose leaves. Grass turns brown. Berries and nuts, harvest time. Winter. Sap stops running. Deciduous trees lose their leaves. Dormant. Waiting for spring. Now the tropics. There is no exclusively spring season. So start with... Cool season. Sap slows but doesn't stop running. Leaves still on trees. The rains have stopped. Everything starts drying out. Hot season. Like spring but arid and parched. Trees looses their leaves and commonly start new leaf growth in a matter of weeks. Before and during the leaf growth trees bud and flower. Until the rains start most of the tropics qualifies as a desert. The rainy season. The major growth season. Cool season, End of November through half way into March. Hot season, March through June. Rainy season, July through October. The logical progression of moist ground then growth is backwards. Nearly all trees and shrubs flower and start new growth during the driest time of the year. Fall doesn't really happen. It's part of the hot season. As a typical example, the common tree here, the Rain Tree, Albizia Saman, looses it's leaves at the end of January. From green to bare branches in about 2 weeks, bare by the end of February. The first week of march is has new leaf growth and by the end of March it is in full flower. The equivalent of Fall, Winter and Spring packed into a little over 1 month. I'm royally confused.
