When you log in to TreeVault®, you instantly get access to more than a billion historical weather records that add color and context to your family’s story. You can, for example, discover whether it was rainy or fine on your grandparents’ wedding day, get to know just how much snow fell on that magical white Christmas your mother remembers from her childhood, or find out how cold it was and how hard the wind was blowing on the winter’s day when your great-grandfather first stepped ashore onto North American soil.
TreeVault Historical Weather® records cover information from more than 100,000 weather stations in 180 countries and their territories, with the oldest records from as far back as the 18th century.
TreeVault Historical Weather uses weather data from the NOAA/NCEI Global Historical Climatology Network - Daily (GHCN-Daily) dataset. For acknowledgements, please click here.
How to get Historical Weather Reports:
- Make sure you are logged in to your TreeVault account. If not, click the TreeVault icon on the main toolbar or in the TreeVault Cloud Services panel on the Current Tree tab on the Plan workspace, and choose Log in. Then enter your email address and password and click the Log In button.
- Click the TreeVault icon and choose Historical Weather. The Historical Weather window then opens.
- Select the location you want a weather report for by dragging and zooming the map and then clicking the location. Or start typing the name of the location in the search field in the top-left corner of the window, then select the full name from the list of suggestions that appear.
To zoom the map in and out and change the map type, use the controls in the top-right corner of the window. They work exactly as they do on the Places workspace.
- Click in the date field to open the calendar. Set the month and year by clicking each item and choosing from the list that appears. You can also move back or forward a month at a time by clicking the left and right arrows. Then click the day of the month you want to see the weather for. Alternatively, you can just type the date directly in the field.
Note: When typing a date for historical weather, you must use the month/day/year format (so 6/7/1974 will be read as June 7th, not July 6th, for example).
- In the Results panel you will see a list of the weather stations closest to the location you’ve selected that have weather data for your chosen date. The positions of the weather stations are marked on the map by numbered green dots. If there are no weather records for the location on the selected date, a message appears telling you the closest date for which weather data is available in that location.
- Click a weather station in the Results list or on the map to see its report for the chosen date. Different weather stations often have different types and amounts of data available. The dot marking the selected station on the map turns brown.
- Click the ̊C / ̊F switch to change the temperature readings between Celsius and Fahrenheit.
- Close the Historical Weather window when you are done.
