Answer 1

Riverside experiences a semi-arid Mediterranean climate with hot, dry summers and mild, relatively wet winters. Temperatures in the summer can exceed 100 but with somewhat low humidity. In the winter, high temperatures average in the upper 60's but may not rise above 55 during rainy days. In January, the coldest month, averages a high/low temperature of 68/43 while August, the hottest month, averages a high/low temperature of 95/64. Riverside receives 10.4 inches of precipitation annually with most of it occurring in the winter and early spring, especially January through March, with February being the wettest month. However, during El Nino years, Southern California can receive considerably more precipitation than average.
