Average Temperatures in January
Delving deeper into the average temperatures in San Diego during January can provide a clearer picture of what to expect. As previously mentioned, the average high temperature hovers around 66°F (19°C), making it a comfortable climate for daytime activities. This mild weather is due to San Diego's coastal location and Mediterranean climate, which moderates temperature extremes. January is one of the cooler months in San Diego, but it’s still significantly warmer than many other parts of the United States and Europe during this time.
The average low temperature in January is approximately 50°F (10°C). This cooler nighttime temperature means that layering clothing is a good strategy. While the days can be warm enough for short sleeves, evenings often require a light jacket or sweater. The drop in temperature is typical for a Mediterranean climate, where clear skies at night allow heat to radiate away from the surface.
Temperature variations can occur within the month. Early January might feel slightly cooler, while late January tends to be a bit milder as the city transitions towards spring. However, these differences are usually subtle and don't drastically change the overall weather experience. It is also worth noting that inland areas of San Diego County can experience slightly greater temperature fluctuations compared to coastal regions.
Compared to other months, January's temperatures are notably cooler than the summer months, which can see highs in the 70s and 80s Fahrenheit.

While January is not the wettest month of the year in San Diego, it does experience a moderate amount of rainfall. On average, the city receives about 2 inches (50 mm) of rain throughout the month. This precipitation typically occurs over several days, rather than continuous downpours, meaning there are still plenty of sunny days to enjoy.
The frequency of rainy days in January can vary, but it’s common to see rain on approximately 5 to 7 days out of the month.
