Dry season starts sometime in October. In general we have absolutely no precipitation for November thru March. Once in a great while, we'll have a very unusual rain during the dry months. For example, we had a torrential downpour on Friday, Dec. 5, 2008, on the very day we were worried that violence would erupt in our city again. It was so unbelievable that we just had to conclude that it was a 'God-incidence.' That is the only rain we have had this dry season apart from a small drizzle for about 15 min. last week.
We will be expecting a few rains in April, and then the downpour will really begin in May and pick up speed until August when it will rain almost everyday.
The photo below is how I am greeted everytime I drive into our compound in March. The purple tree (to the left) is the jacaranda. It produces a beautiful purple 'carpet.' We call the red flowering tree the Flame Tree. (I don't know its actual name.) The multi-colored flowering vines in the background and in the photos above are bouganvillia.
