The climate of Anaheim
Renowned for its Mediterranean climate, Anaheim finds itself categorized in the hot summer region under the Köppen climate classification as Csa. Given its geographical positioning in California, the weather throughout the year is more often than not, moderate, with mild, wet winters and warm, dry summers. Despite these overarching seasonal characteristics, each month carries distinct weather dynamics all year round.
The average high temperatures range from 64°F (17.8°C) in December to an apex of 83.5°F (28.6°C) in August - attesting to the welcoming warmth that graces Anaheim through the majority of the year. In contrast, the lows exhibit a slighter variation, spanning between 50.2°F (10.1°C) in February to 65.5°F (18.6°C) in August. The relative humidity hovers mostly between 54% and 65%, making Anaheim a location with a rather balanced atmospheric moisture content, and avoiding extreme dry or humid conditions.
From a rainfall perspective, Anaheim becomes a tale of two distinct halves. The first half, from January to July, sees a gradual drop in rainfall from 1.26" (32mm) in February to a minimal 0.04" (1mm) in June. However, an upward surge is observed from August onwards, culminating in December with 1.54" (39mm) of rainfall. Correspondingly, the number of rainfall days also follows the same trend, highlighting December as the wettest month with 6.6 days of rain.
The interaction between sunlight and cloud behavior in Anaheim further elucidates its weather profile. Sunshine hours peak in the summer months, reaching their zenith at 12 hours per day from June to August. Cloud cover, conversely, is least pronounced during these times, dropping to as low as 8% in July. Indeed, summer is when Anaheim basks in its maximum light and minimum obscurity.
