Where can I find historical temperature data?

Historical temperature data is one of the most requested weather measures. Whether you are looking for temperature trends for your neighborhood, seasonal temperature changes to manage an outdoor business, or the exact temperature at the time and date of a specific event, a weather data service such as Visual Crossing Weather can provide temperature data easily using global historical reports going back to 1970.

What temperature measures are available?

Temperature is typically composed of three values, and they are Minimum Temperature, Maximum Temperature, and average (mean) Temperature. The first two represent the minimum and maximum temperatures respectively reported during the period of this weather record. For example, if the weather record is a daily weather record, the minimum temperature value is the minimum temperature reported for that day. The maximum value is the maximum reported for that day.

The average temperature is the mean temperature calculated by combining all of the weather reports during the period of this weather record. For example, if the record is a daily weather record, then the temperature reported is the the average (mean) value for temperature across the entire day.

What are the units and range for historical temperature data?

Temperature data is provided in degrees Celsius or Fahrenheit depending upon the unit system that you select. As for range, temperature varies widely around the world and seasonally. For refence, the hottest temperature recorded on Earth was 93.9 °C (201 °F) in Death Valley, California, and the coldest temperature was recorded via satellite in Antarctica at −93.2 °C (−136 °F).

How can I find the temperature for a specific location and date (or date range)?

Visual Crossing Weather offers several ways to find the temperature for a specific location and date. The easiest option is to use the free Weather History dashboard. Simply enter the location and date (or date range), and you will be able to see formatted page showing the weather details that you requested.
