We have found Wxsim to be very accurate in its temperature forecasts especially in the first 48 hours. Forecasts are updated 5 times daily. Wxsim uses past and current temperatures of Mission Trails and surrounding airport stations and upper air temperature patterns reported at San Diego Miramar MCAS. In addition this forecast takes into account sea breezes caused
by the relatively cool adjacent Pacific Ocean. FOUS (Forecast US) and GFS (Global Forecast System) weather computer models are also inputed to arrive at the forecast solution.

About San Diego, California
San Diego is just 20 miles north of Mexico, situated in the rolling hills and mesas that rise from the Pacific shore to join with the Laguna Mountains to the east. Its bay is one of the country's finest natural harbors. The city covers a large area of vastly different terrain: miles of ocean and bay shoreline, densely forested hills, fertile valleys, and mountains, canyons, and desert. The climate varies in a similar manner. On the coast, the temperatures are mild and constant, while in the desert areas, the temperature can fluctuate as much as 30 degrees in one day. San Diego is about 120 miles south of Los Angeles.
The climate in San Diego is tempered by the Pacific Ocean air, keeping the summers cool and the winters warm. Severe weather is rare in the area; snow is almost unknown, and the city averages only three thunderstorms a year. September and October often bring hot eastern winds from the desert, producing what are usually the hottest days of the year.

About The Mission Trails Area
This personal weather station is located within one-half mile of the Visitor's Center at Mission Trails Regional Park in San Diego, California.
Mission Trails Regional Park encompasses nearly 5,800 acres of both natural and developed recreational acres. Its rugged hills, valleys and open areas represent a San Diego prior to the landing of Cabrillo in San Diego Bay in 1542. Centrally located and only eight miles northeast of downtown San Diego, Mission Trails Regional Park provides a quick, natural escape from the urban hustle and bustle.
Started in 1974, Mission Trails Regional Park has become one of the largest urban parks in the United States. The Park contains over 50 miles of hiking, mountain biking and equestrian trails, boating on Lake Murray, and a state-of-the-art Visitor's Center. Originally used by the Kumeyaay, the park is the site of the Old Mission Dam, built to store water for the Mission San Diego de Alcala.
Campgrounds are available at the park, campers have their choice of 46 primitive (no water or electricity) sites for tents or recreational vehicles. Each site contains picnic and food preparation tables, a fire box, tent pad, and parking space with water, bathrooms and hot showers provided nearby.
Lake Murray is very popular for bicycling, jogging, walking, rollerblading, and picnicking. The reservoir has large mouth bass, bluegill, channel catfish, black crappie and trout (stocked November-May).
