Question

Where can I find yearly annual averaged temperature data for every city and town in the US and Australia for a heatmap?

links are good

Answer 1

The resource at GOSIC: http://gosic.org/content/gcos-surface-network-gsn-data-access

It's not every town and city - but it's the most comprehensive coverage for international comparison.

Of course, you could go big and get the data straight from the University of East Anglia: http://www.cru.uea.ac.uk/cru/data/temperature/#datdow

But be prepared for a steep learning curve....

There's NOAA coverage for detail in the USA: http://www.ncdc.noaa.gov/land-based-station-data/quality-controlled-local-climatological-data-qclcd

and for Australia the link is: http://www.bom.gov.au/climate/change/

... have fun coloring in things Purple!

Answer 2

I've used PRISM data before: http://www.prism.oregonstate.edu/

Some of it's free, some you have to $$$

Answer 3

The Weather Underground Weather API

has the option (free) for historical weather is coverage more than US and Australia

There is a pricing structure if your are doing more than 500 API calls a day.

But worth looking in into:

Answer 4

For Australia, climate data is available from the Bureau of Meteorology.

Answer 5

Try Worldclim it's a raster set, with several clim average measurements from 1950 - 2000.
