Jim,
I’m not sure if this has been covered here before, but here are a few links to Government climate data and maps in the US. Microclimate data are represented as well, to a degree limited by the number of stations:
Climate Maps of the United States – Lookup Page
Monthly Station Climate Summaries – By Station
For those interested in wind speeds and patterns across the USA for whatever reason, the map link above can be supplemented with the data for the major population centers.
Thanks again for your hard work, – The DFer
JWR Replies: Thanks for sending those links. They are very useful for both assessing the “livability” of various locales. Along with prevailing wind maps (which are useful for radioactive fallout prediction), I consider maps an essential planning tool. I strongly recommend that anyone considering retreat locales should do a climate study first. It is notable that climate and growing season duration are what caused us to rule out areas east of The Great Divide when we went searching for the Rawles Ranch.
