1. The Pacific Ocean is freezing.
Do not expect warm tropical water when visiting the Pacific Ocean — even in the summer. Although the ocean is beautiful, it averages 51-60 degrees Fahrenheit. If visiting outside of the summer months, pack or rent a wetsuit.
2. Earthquakes are frequent, but often of negligent magnitude.
Although we have small earthquakes daily, a lot of Californians have never actually felt a quake. We don’t get warnings, and larger earthquakes rarely happen. In addition, the epicenters are generally in unpopulated areas. Unlike tornadoes, hurricanes and more extreme storms, there is no regularity to earthquakes. The scariest part is the unpredictability, but this shouldn’t deter you from visiting. Be prepared by ensuring your gas tank is always at a half-tank full or fuller, and that you have food and water stored. P.S. Oklahoma officially has more earthquakes than California (thanks to good old’ fracking).
