Average Weather and Climate

As you can see from the charts and graphs below there is a fairly small difference in seasonal temperatures, on the other hand the amount of seasonal precipitation fluctuates greatly from season to season. It can be seen that there is an inverse relationship between temperatures and precipitation. As temperatures increase in the summer months the precipitation amounts tend to be low and vise versa.

San Diego has a very moderate climate due to it's geographic setting on the west coast of North America. Being on the west coast helps moderate its climate even more due to the cold ocean currents that move from the North Pole to the Equator. Because of its location on the coast San Diego experiences higher humidity than that of a continental location. These higher humidity rates lend to a lower Bowen Ratio which is the amount of sensible heat to latent heat. It can be estimated that the amount of latent heat is about twice as much as that of sensible heat meaning a ratio around .5. In the Geebit model when increasing albedo by .1 the temperature decreases by 13.1 degrees Fahrenheit to 28.8 degrees, when decreasing the albedo by .1 the temperature increases by 12.1 degrees Fahrenheit to 54 degrees. when increasing the green house factor the temperature increases by 7.9 degrees Fahrenheit to 49.8 degrees, when decreasing the green house factor the temperature decreases by 8.3 degrees Fahrenheit to 33.6 degrees. These changes observed will have an effect on the average temperatures experienced but to a lesser degree than that of a continental location due to the moderating effect of it's coastal location.
