Finding Historical Weather Data

Historical weather is a great way to connect with our ancestors because weather affected them in the same way it does us today.  Maybe even more so if they were farmers whose livelihood depended on a bumper crop.

Wouldn’t it be fun to know what the weather was like the day your grandparents were married? Or if it snowed the day your dad was born?  If you are writing narratives about your ancestors, you could add in historical weather references for special events, assuming you were able to locate accurate historical weather information for the location and date the event occurred. 

Using readily available Internet resources, you can research the weather your ancestors encountered on that special date with a bit of digging.

1945 – Present
