AT Climate/Weather Page

[postholer.com]

You can now see how temps and precipitation is looking along the entire AT. If you're familiar with the PCT/CDT Postholer, the AT now has its own page.

The AT page however is water based, not snow based due to the lack of snow sensors. Here's a quick look at the end of the last water year:

Finding sensors with long term historical data directly on the AT is difficult at best. With that in mind the data is collected from airports in the area that have data. It will give you an idea of above/below normals for that area. Precip and temps on the actual trail will vary.

Additionally, you have links to the AT maps and NWS weather forecasts.


Enjoy!

Love to hike with people who know bird,flower names and climate! Thanks. Where's Weathercarrott's study? anyone know?

These are good websites to give an overall big picture of a certain region, which is very important, but kind of useless for hiking through these areas. Just because an area is depicted to be in a D4 drought (Exceptional Drought) doesn't mean there's no water, yes water will be scarce, but not non-existent (The highest drought rating currently on the AT is D3).

Bottomline - These are good websites, but don’t compare to old-fashioned boots-on-the-ground hiker reports.
