Offline Weather Forecasts for the
Appalachian Trail.

From enduring days of the "green tunnel" rain to sudden drops in temperature in the Whites, knowing what's coming is critical for morale and safety on the AT. Get accurate forecasts sent straight to your phone, no cell signal or expensive Garmin required.

The Appalachian Trail
Weather Problem

While the AT crosses numerous roads and towns, long stretches—especially through the Smokies, the 100-Mile Wilderness, and higher elevations—often lack reliable cell service.

Relying on out-of-date forecasts you pulled three days ago in town can lead to miserable days hiking in cold rain, or getting caught in completely unexpected weather patterns over exposed ridges like Mount Washington.

Why Thru-Hikers Love
SMS Weather On Demand

Thru-hikers are obsessed with two things: saving weight and saving money.

Zero Base Weight Increase If you are carrying a modern smartphone (like an iPhone 14+ or the Google Pixel 9 and Samsung Galaxy S25 series on Android 15+), you already have satellite messaging built right in. You don't need to carry an extra 4oz Garmin InReach Mini just to pull weather.
No Subscription Fees Don't pay $15 to $35 a month during your 5-month hike for a service you only use a few times a week. With SMS Weather On Demand, you only pay pennies per request.
Pinpoint GPS Accuracy Don't look at the forecast for a town 3,000 feet below you. Text your exact coordinates via satellite to get a hyper-localized temperature, wind, and precipitation forecast for exactly where you are standing on the ridge.

How It Works

The initial setup happens while you're online, so that you're ready to go when you're off the grid.

Get Set Up Online

Create an account to verify your phone number. Then use the "Add to Home Screen" feature on your phone to install and run our lightweight application so it can be used offline.

Go On Your Adventure

Head out even where there's no internet. As long as your phone has the capability to send texts or use satellite messaging, you're covered.

Request Your Forecast

Open the app from your home screen. It uses your GPS location and your selected forecast options to help prepare a unique text for your request.

Send and Receive

Just hit 'send' in your messaging app. You'll get a weather forecast texted back in moments.

Please note: Standard messaging rates from your cellular or satellite carrier will apply for the SMS messages you send and receive. Coverage and Deliverability are also dependent on the cellular/satellite messaging providers you use.
