In addition to the helpful resources cited above, I'd like to add another that may be of interest.
Dark Sky is an app that delivers localized weather information throughout the world and it has an interesting historical function.
For example, if you list Burgos at the top of its page, it will tell you the current and predicted temp/weather for the next week there. However, if you scroll to the bottom and click on Time Machine, it will present with a calendar you can use to go back to a previous date, such as one year ago today, showing details of the weather in Burgos then.
It is also interesting because in this mode you can quickly flip forward and backward across days and weeks of daily weather to get a good picture of the changing weather at that place and time. This lacks the generalized information you would get from seeing annual average temperatures compiled over several years. But on the other hand, it can give you a good and quick review of weather details in one place in one year over many days.
So, one year ago in Burgos the temperature range was 32/46, Sunrise/set was 7:40/7:15 and it was partly cloudy. But the viewer can also quickly scan over those days to see how the temps steadily range up into the 50s a week later. Also, there was only four hours of light rain over the two weeks following March 3, 2021.
