Berkeley (CA) Temperatures: Monthly Averages and Year-Round Insights
On this page, we’ll explore Berkeley’s temperature statistics in detail, including day and night variations and monthly averages. We’ll also compare the annual temperature to other cities in the United States of America.
Monthly Temperature Averages
In Berkeley, seasonal changes bring about a moderate variation in temperatures. Average maximum daytime temperatures range from a comfortable 24°C in September, the warmest time of the year, to a moderate 13°C during cooler months like December. At night, minimum temperatures typically average around 6°C during these months.
The chart below illustrates the average maximum day and minimum night temperatures in Berkeley by month:
Typically, the coolest time of day is between 4 AM and 6 AM, while the hottest time occurs around 3 PM, when the sun’s heating effect is strongest. September, the city’s warmest month, experiences 270 hours of sunshine.
The chart below shows the average temperature throughout the year:
December, the city’s coldest month, receives about 125 mm of rainfall spread over roughly 13 days. For more information, please visit our Berkeley Precipitation page.

Berkeley Temperatures Compared World Wide
Berkeley’s average annual maximum temperature is 20°C. Let’s compare this with some popular tourist destinations:
Athens, Greece, experiences an average annual temperature of 23°C, with hot summers and mild winters typical of a Mediterranean climate.
Meanwhile, Queenstown, New Zealand, the average annual temperature is significantly lower at 10°C, with mild summers and cold winters.
Meanwhile, Buenos Aires, Argentina, enjoys a humid subtropical climate with an average annual temperature of 23°C, featuring hot summers and mild winters.
Melbourne, Australia, has a slightly cooler climate, with an average annual temperature of 20°C.
How does the temperature feel?
Humidity is an essential factor in how you experience temperature. When a warm period is accompanied by high humidity, it results in a higher perceived temperature. This is especially true when temperatures exceed 25°C, as it can cause greater discomfort.
In Berkeley, during the coolest month, December, you will experience 78% humidity, which is considered high. This is accompanied by an average maximum temperature of 13°C. In the warmest month, September, the humidity is 73% combined with an average maximum temperature of 24°C, which creates a high-feel temperature.

How are these Temperatures Measured?
Generally, temperature data depicting climate is usually given over a 30-year average in order to reduce short-term fluctuations and reveal better long-term trends in climate conditions.
This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.
Sea vs. Land Temperatures
The influence of nearby oceans or large water bodies significantly affects local temperatures:
- Ocean Influence: Coastal regions tend to have more stable temperatures, as large bodies of water absorb and release heat slowly. This often results in milder winters and cooler summers compared to inland areas.
- Continental Climates: Landmasses well away from large bodies of water tend to show greater extremes in temperature, having hotter summers and colder winters because of the absence of water as a moderating influence.
