The northern parts of Baja seem to be aligned with the weather in Southern California – Winters are cooler and tend to rain, have long periods of wind and foggy conditions until the summer months.
If you’re one who loves to dive, then the Sea of Cortez is the place for you. The temperature of the water during the summer months is usually an average of 72 to 75 degrees Fahrenheit (or 21 to 24 degrees Celsius), and only about 61 degrees Fahrenheit (16º C) in the winter.
One thing to keep a keen eye out for is the tide swings. In some parts of Baja Peninsula, the tides can range from 12 to 16 feet. Which, needless to say, can cause some problems for boaters out diving, people collecting clams, and even just playing around the shoreline.
