La Mesa, CA
La Mesa is a city in San Diego County, California. The population was 57,065 at the 2010 census, up from 54,749 at the 2000 census. It was founded in 1869 and officially incorporated as a city on February 16, 1912. Its official flower is the bougainvillea.
La Mesa is approximately 12 miles (19 km) east of the Pacific Ocean. Because of this, La Mesa typically experiences warmer temperatures than San Diego, which mostly lies significantly closer to the Pacific Ocean. La Mesa has a Semi-arid Steppe climate. La Mesa typically has hot, dry summers and warm winters with most of the annual precipitation falling between November and March. The city has dry weather with around 13" of annual precipitation. Summer temperatures are generally hot, with average highs of 78°F-92°F (26°C–33°C) and lows of 56°F–68°F (13°C–20°C). Winter temperatures are warm, with average high temperatures of 66°F–77°F (19°C–25°C) and lows of 46°F–58°F (8°C–14°C). The climate in the San Diego area, like much of California, often varies significantly over short geographical distances resulting in micro-climates. In San Diego's case this is mainly due to the city's topography (the Bay, and the numerous hills, mountains, and canyons). Frequently, particularly during the "May gray/June gloom" period, a thick "marine layer" cloud cover will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately 5–10 miles (8.0–16 km) inland. This happens every year in May and June. Even in the absence of June gloom, inland areas tend to experience much higher temperatures than areas closer to the coast.
