The temperature in Ashburn, Virginia is the current measurement of atmospheric heat in this Northern Virginia suburb, typically ranging between -5°F (-21°C) in winter and 90°F (32°C) in summer. This data comes from NOAA-certified weather stations reporting hourly updates.
Professional weather stations use aspirated thermometers housed in white louvered enclosures to measure air temperature accurately. The National Weather Service station near Dulles International Airport provides official readings for Ashburn. These sensors avoid direct sunlight and ventilation ensures proper airflow for precise measurements.
| Measurement Type | Typical Range | Use Case |
|---|---|---|
| Dry Bulb Temperature | -5°F to 90°F | Standard air temperature reading |
| Wet Bulb Temperature | 10°F to 85°F | Humidity factor measurement |

Ashburn's weather affects daily life for its 50,000 residents. Schools adjust outdoor activities based on temperature alerts, and local businesses monitor cold snaps that might impact operations. The area's proximity to the Potomac River creates microclimates that can vary by several degrees from neighboring regions.
According to NOAA's Climate Data Center, Ashburn experiences an average of 30 days per year above 90°F and 60 days below freezing. These patterns help residents prepare for seasonal changes and potential weather-related disruptions.
Many people assume temperature readings come from airport locations, but Ashburn's official data actually originates from a dedicated weather station in nearby Sterling. Another misconception is that urban heat islands don't affect suburban areas - in reality, Ashburn's development has increased local temperatures by about 2°F compared to rural surroundings.
When I checked the temperature during a winter storm in January 2023, the official reading showed 28°F while my home weather station registered 32°F. This discrepancy demonstrates how microclimates within Ashburn can create significant variations in reported temperatures.
