After reading the thread
Optimal driving route for 70 degree high every day yearI got curious whether it was possible to find 70-degree days year-round. To answer this question, I used data from nearly 7,200 weather stations run by the national weather service to create a Google Map for each month of the year.
The maps show monthly averages of daily high temperatures for each weather station, averaged over 30-years time (to smooth out any extremes due to unusual circumstances).
With the '70-degree days' goal in mind, I keyed these maps to show the following:
- Hearts in a green circle are the 'sweet spot': 68-72 degrees.
For a bit of context, I also color-coded a 5-degree range above and below that sweet spot:
- Tiny blue dots are daily high temperatures between 63 and 67 degrees.
- Tiny orange dots are daily high temperatures betweem 73 and 77 degrees.
The remaining tiny gray dots are temperatures that fall outside this overall 15-degree range of temperatures (so, either below 63 or above 77).
Anyone who's seriously interested in mapping out where to be for year-round 70-degree days will find these maps invaluable. July and August are the months with the fewest locations in that sweet-spot temperature range (68-72) so I suggest first picking places from those months and then planning the rest of your travels around those relatively limited options.
Each map will take a few moments to load because of the number of weather stations it includes. Once loaded, make sure the check box next to each of the 4 layers is checked. This will make visible the locations. All 4 layers ought to be checked (I had to use 4 layers because Google Maps limit each map layer to a maximum of 2,000 data points. Given nearly 7,200 weather stations, that's 4 layers).
These are standard Google Maps which I've shared to anyone who has the link. No sign-in is required, but they are read-only. For anyone who may wish to use this data in their own Google Maps, I've exported the data for each month's map into .kmz files. If anyone would like to import this data into their own Google Maps, let me know and I'll upload those files someplace where you can download them.
Happy journeys!
