From October to April is our rainy season. In 2010, our first measurable rain arrived on October 6th and by the end of February we had received 12.58 inches of rain. This year our rainy season began on October 5th, but as of today, March 5, 2012, we have received only 5.375 inches.
The average annual rainfall in Los Angeles since 1878 is 14.98 inches. Typically, weather forecasters measure our rainfall against a rounded-up 15 inches. If you look at the graph of annual recorded rainfall, patterns are tricky to spot. There are years of less than 5 inches spiked with years of 20 or 30 inches.

If rain doesn’t arrive soon, we will probably arrive in June with a total of less than 8 inches of rain, drought levels. This impacts every living thing in Southern California, from frogs and fish, to agriculture and humans. The hillsides and their wild residents can’t ask for more water from a river far away. They have to survive on what falls from the sky.
