Diving in Baja California is a year-round activity. The rainy monsoon season lasts from June to September, but precipitation is much higher on the northern Baja California than on its eastern and western coast. The high season for diving is from July to November due to better visibility and warmer water. The average air temperature stays between 20C/68F and 33C/91F. The average water temperature on the Pacific coast varies from 13C/55F to 19C/66F and in the Sea of Cortez between 19C/66F and 29C/84F. The average water visibility stays within 10-35m/32-114ft range. Currents generally vary from low to moderate.
