I would suggest that the Chumash perform a Rain Dance!
In late August, when it is quite dry, especially in the Southwestern United States, Native American tribes used to do a rain dance. Many Native Americans still perform the ritual today, and it can be seen on several reservations in the United States.
Men and women gathered together for a rain dance and wore special headdresses and clothing. The jewels used in the clothing, such as turquoise, had special significance, as well as the patterns on the clothing and the use of goat hair in the headdresses.
How it’s done:
Wear turquoise and feathers.
Find an outdoor space where you have plenty of room to move around.
Spin around in circles.
Speed up your spinning and chanting.
We desperately need the rain — let’s dance!

One year in Santa Barbara, we did the Rain Dance on the beach, and we were very successful!
