Climate vs. Weather
Before we get into the details of the Washington DC climate, it’s helpful to understand the difference between climate and weather, two terms that are often used interchangeably but mean very different things. Understanding this distinction is key to interpreting Washington DC weather monthly trends and knowing what kind of temperatures, rainfall, and seasonal changes to expect throughout the year.
According to the National Centers for Environmental Information, weather is the mix of events that happen every day in our atmosphere. Even though there’s only one atmosphere on Earth, Washington DC weather by month can vary just as much as it does across the globe. Weather includes daily highs and lows, the chance of rain, or whether you’ll need a coat tomorrow. It can change by the minute, hour, or day.
Climate, on the other hand, refers to the average of those weather patterns over a long period (typically 30 years or more). So, when we talk about the climate of Washington DC or the climate in Washington DC, we’re talking about long-term patterns, not just what’s happening this week.
Washington DC Seasons
The Washington DC climate features four distinct seasons, giving residents a full range of seasonal experiences, from colorful autumns to hot, sunny summers.

Unlike some regions that experience a monsoon or wet/dry season pattern, Washington DC doesn’t have a defined rainy season. Rainfall is fairly evenly distributed throughout the year.
