Find your city's temperature history

In Sunday's post I'm going to be looking at how outside air temperature impacts your home's energy consumption (mostly because of heating/air conditioning).  In order to do that, I had to find history data on weather in my city.  This was actually harder than I thought.  Here's how to do it in case you would like to do some detailed analysis on your home's energy consumption.

1.) Go to - This is actually a great resource for all weather related data

2.)  At the very top of the page, type in your zip/city and state and and press Go. - This will pull data from the weather station closest to your city.  If you want to find weather data to a location closer to you, you have the option to choose this.  The weather stations are usually located at airports.

3.)  Scroll down a little bit until you see the "History and Almanac" section.  Start it at the month you want to start getting data from (in my case I wanted to see data for the month of August) and click View. wunderground_history 4.) At the next page you will be taken to the "Daily Summary" page.  Click on the tab for "Monthly Summary".wunderground_monthly_history


5.)  Scroll down to the bottom of the page and you will see the section "Daily Observations".wunderground_daily_observations There's your data.  At this point, you can copy the data and paste into excel to perform some more detailed analysis (just make sure to "paste special; text"). Now you have the data you will need to compare how your home's energy consumption is impacted by the temperature outside.  That will be my next blog! Seen here: Outside Temp and Energy Consumption.

Temperatures this summer have been hovering in the upper 80's and low 90's. I'm almost 60 years old and have lived here all my life. It's always been this way. Yesterday's "average high" was 82. The actual temperature was 88. That should mean that there must have been a day with an actual high of 76 to make the average, but in my whole life I doubt that there has been one August 4th with a "high" that "low". How are these averages calculated? Thank you.
Thank you for the great step by step instructions. Very useful for those who are uncomfortable with using computers and websites. As we say where I live - "You are da bomb!"
Just to say I found this very useful when comparing the average temp for this Fall 2011 to last Fall to see how my newly insulated home was performing. GREAT. Thank you.
A big thank you!! The information was very usefull..
VERY useful info! I wanted to compare this years temperatures in december to last year because it felt colder to me. Sure enough, it shows that temperatures are indeed about 5 to 10 degrees colder each day... Which is what is driving up bills. Thanks again.
I've developed a passive solar hot water system with patent pending "SNAP FROST PROTECTION" system. Several years ago I got historical temperatures by day and month which had historical avg hi,low,mean, record low and year of record low. It was free. I tried getting back to the data and I don't know but it doesn't work. Does anyone know what site has this data?
this site is worthless to me. Either that or I can't navigate it appropriately. When I click on weather records for 1983, the latest I can bet is 1996. Not good enouth. I'm looking for historical temperature records, and historical means older than 20 years.
HI Carol, As with all things. If there is a need, there is a service that provides it. The answer is almost never, NO but it is YES there is a price. The website weather-warehouse (dot) com seems to have lots of historical data going back quite a while. For a price. I don't know the price because I was looking for free information to satisfy my own curiosity. Good luck with your search Carol.
