Factors Influencing Pasadena's Weather

Okay, guys, let's look at what actually influences this lovely Pasadena, CA weather. Several factors work together to create the unique climate we've been talking about. One of the biggest influences is the city's geographical location. Nestled between the San Gabriel Mountains and the Pacific Ocean, Pasadena benefits from both mountain breezes and marine air. The mountains help block some of the extreme weather, and the ocean moderates the temperatures. Another important factor is the city's proximity to the Pacific Ocean. The ocean currents bring in cooler air during the summer, keeping temperatures relatively moderate. This influence is especially noticeable during the afternoons when the ocean breeze kicks in, providing a welcome respite from the heat. The prevailing wind patterns also play a role. Winds generally blow from the west, bringing in clean air from the ocean. However, during certain times of the year, particularly in the fall, Santa Ana winds can bring hot, dry air from the deserts to the east, causing temperatures to soar and humidity to drop. This can sometimes lead to increased fire risk. Urbanization also has an impact. The
