Last year the rainy season started on September 23rd.
Today, on September 30th, we had 95° F (35° C) at 5:30 PM; in the Valley it was even hotter. These temperatures are supposed to last until the weekend. Whether there will be any rain later is still somewhat doubtful.
On the upside: the mornings are wonderful. It is cool and dark and quiet. No rain, but a wonderful waning moon hanging over the tree tops. Daylight and the heat are still a bit away (as it is only right and proper at 6:00 AM).
