Historical collection | Part 3: History Bulk

OpenWeather has been providing consistent and accurate data on current weather, forecasts and weather history for many years.
The historical weather data has a wide spectrum of applications. It is used intensively in such important sectors as energy, major transport and construction.
Aiming to simplify the process of obtaining data, we created the Historical Weather Data collection – a flexible and unique combination of our products (including APIs).

This article describes one of these products: History Bulk.

What we offer

History Bulk is a one-time export of historical weather data going back up to 40 years. You can choose any period of time from 1 January 1970 until now for your order. Data is provided with an hourly step. The historical data archive includes all essential weather parameters, such as temperature, precipitation, wind, atmospheric pressure and many more.

Weather parameters in History Bulk

Temperature:
Min temperature (optional) – This is the minimal observed temperature (within large megalopolises and urban areas).
Max temperature (optional) – This is the maximal observed temperature (within large megalopolises and urban areas).

Feels like temperature – this accounts for the human perception of the weather.

Wind – if you choose this parameter, the order will contain two detailed wind parameters:
Wind speed – by default, this is in metres/second.
Wind direction – in degrees (meteorological).

Atmospheric pressure (on the sea level) – hPa.

Humidity – %.

Clouds– %.

Weather conditions – This is a short description of weather conditions containing weather icons. For example, “range of thunderstorm”, “drizzle”, “rain”, “snow”, “clouds” (including extreme conditions such as “tornadoes” and “hurricanes”). The list of weather condition codes with icons is here. You can also get the output in your language.

Rain – mm.

Snow – mm (in liquid state).

How to get historical weather data

OpenWeather’s Marketplace allows you to get weather data quickly and without having to register. The flexible, convenient interface helps you to customise your order by choosing the required weather parameters, units format and file format (CSV or JSON).

By the way, there are several options to specify the location: you can click on the map, or enter the coordinates or town/city name. For your convenience, we have developed one more option – uploading locations via a CSV file. This might be helpful if you are interested in getting weather data for a large number of locations. You can also contact us directly at info@openweathermap.org to order data for an extensive number of locations. Our experts will process your list of locations and export the requested data for you.

The price is highly competitive – only $10 per location. You can find more about ways to access historical data from our price page.
