Editing La Mesa, California (section)

=== Climate ===

La Mesa is approximately {{convert|10|mi|abbr=on}} east of the Pacific Ocean. Because of this, La Mesa typically experiences more extreme temperatures than San Diego, most of which lies 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 {{convert|13|in|abbr=off|sp=us}} of annual precipitation. Summer temperatures are generally hot, with average highs of {{convert|78|-|92|F|C}} and lows of {{convert|56|–|68|F|C}}. Winter temperatures are warm, with average high temperatures of {{convert|66|–|77|F|C}} and lows of {{convert|46|–|58|F|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 {{convert|5|–|10|mi|km|0}} inland. This happens every year in May and June. Even in the absence of June gloom, inland areas tend to experience higher temperatures than areas closer to the coast.
