Yuba City does not receive significant snowfall (greater than 1 inch).
We use dew point to measure humidity comfort since it shows whether sweat can evaporate from our skin to cool us -
lower dew points feel drier and higher ones feel more humid. When sweat evaporates, it draws heat from our skin,
which is how our bodies naturally cool down.
Generally, if the dew point temperature is below 50ºF, humidity levels make the air feel dry.
If the dew point temperature is between 50-60ºF, moisture levels are comfortable.
When the dew point temperature exceeds 60ºF, the air will feel noticeably humid.
If the dew point temperature climbs to 70ºF or higher, the air will feel muggy and unpleasantly uncomfortable.
In Yuba City, the humidity level remains comfortable throughout the summer, providing a pleasant environment for residents and visitors alike.

The shortest day in Yuba City falls on December 21 with about 9 hr 24 min 25 sec of daylight.
How this is calculated: Based on the location’s latitude and longitude, we determine the local time zone and calculate daily sunrise and sunset times using a solar position algorithm. The difference between sunset and sunrise gives the day length. Repeating this process for every day of the year allows us to identify the longest and shortest days for that location.
In Yuba City, the month with most sunshine hours is July (13.5 hrs), and the month with least sunshine hours is January (4.8 hrs). Total annual sunshine hours: 3403 hrs.
In everyday terms, this represents the average amount of daily sunlight a location receives — often described as "hours of sun per day," "average daily sunlight," "sunshine duration," or "sunlight daily". These measures all capture how bright and sunny a place really feels across the seasons.
Tracking sunshine hours and number of sunny days can also highlight areas with limited daylight, which is especially important for people managing Seasonal Affective Disorder (SAD). This information is also a practical guide when comparing climates, planning a move, choosing a vacation spot, or avoiding long, gloomy winters.
How this is plotted: In the chart below, each day is represented as a 24-hour cycle, divided into sunshine hours, cloudy daylight hours, and night. For example, if a location had 10 hours of daylight and 6 of those were sunny, the chart would show 6 hours of sunshine, 4 hours of cloudy daylight, and the remaining 14 hours as night.
Average Monthly Sunshine Hours in Yuba City
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Sunshine (hrs) | 4.8 | 6.4 | 7.8 | 9.8 | 11.6 | 13.2 | 13.5 | 12.5 | 11.1 | 9.1 | 6.5 | 4.9 |
In Yuba City, the month with most sunshine percentage is July (94.0%), and the month with least sunshine percentage is January (50.0%).
Unlike cloud cover data, which represent average conditions over the full 24-hour day (including night), sunshine percentage looks only at the daylight hours. This makes it a more practical measure for everyday use — whether it’s tracking seasonal changes in sunlight to manage Seasonal Affective Disorder (SAD), planning outdoor activities, choosing travel destinations, or simply finding places that avoid long stretches of gloomy weather.
How this is calculated: Sunshine percentage is calculated by comparing the actual sunshine hours in a day to the maximum possible daylight hours (based on the sun’s position at that longitude/latitude and time of year). For example, if a location had 6 hours of sunshine during a 10-hour day, the sunshine percentage would be 60%. This gives an easy-to-understand measure of how much of the available daylight was truly sunny.

In Yuba City, the month with most solar energy is June (8.2 kWh/m²), and the month with least solar energy is December (1.8 kWh/m²). Total annual solar energy for Yuba City is 1873 kWh/m².
How this is calculated: Solar energy here refers to the total shortwave radiation (sunlight) reaching the ground, measured as Global Horizontal Irradiance (GHI). It combines both direct and diffuse sunlight scattered by the atmosphere. Hourly GHI values are converted into daily energy (in kWh/m²) by summing the radiation over each day. To highlight reliable patterns rather than day-to-day weather noise, the results are averaged over many years. In everyday terms, GHI reflects the total amount of sunlight energy available at a location.

myPerfectWeather.com uses data from the National Center for Environmental Information, with 15,000+ weather stations across the USA reporting precipitation, snowfall, humidity and temperature. The data is collected and processed over a 30-year period from 1991-2020, ensuring accuracy. A sophisticated algorithm identifies nearby weather stations for each city and calculates weather data based on a weighted average of station data, ensuring accuracy and relevance. We also source population information from the US Census database and use industry-leading technology from © OpenStreetMap and Leaflet to power our maps. With these powerful tools, you can easily visualize and explore weather patterns in your area with confidence and accuracy.
The GHI and DNI data come from the U.S. National Laboratory of the Rockies, formerly the National Renewable Energy Laboratory (NREL), which uses its Physical Solar Model (PSM) together with satellite observations from the GOES weather satellites. The model first calculates the theoretical amount of solar radiation based on the Sun’s position for a given location and time. It then adjusts those values using satellite measurements of real-world conditions — such as clouds, haze, smoke, and aerosols — that block or scatter sunlight. To highlight reliable patterns rather than day-to-day weather noise, the results are averaged over many years.
Sunshine hours (or Sunshine duration) per day are estimated by counting the time when direct sunlight (measured as Direct Normal Irradiance, or DNI) exceeds 120 W/m², following the World Meteorological Organization standard. Sunshine hours are calculated only during daylight and are averaged over many years to capture long-term patterns.
