Live Weather Data for Safe Trail Adventures 🌤️
Real-time weather overlays, forecasts, wind data, and sun/moon information to plan and execute safe hikes
Live Weather Radar 🌧️
See real-time weather patterns overlaid directly on your trail map. Precipitation appears as a color-coded overlay showing rain, snow, and intensity levels.
Storm Movement Tracking 🌧️
Watch storm fronts move across the landscape in real-time. The radar animation shows you exactly where rain is falling right now and in which direction the storm is moving. Make critical turnaround decisions based on actual storm location, not guesses. If a storm is 10 miles away moving toward you, you have time to descend. If it's 2 miles away, get off the exposed ridge immediately.
Precipitation Type Detection
Distinguish between rain and snow on the radar. Snow changes trail conditions dramatically—slippery, hidden hazards, route-finding difficulty. Know whether incoming precipitation will be rain (you can usually continue hiking) or snow (may require turning back or changing routes). Critical for spring and fall hiking in mountains where snow is possible.
Intensity Levels 💦
Color gradation shows precipitation intensity: light rain, moderate rain, heavy downpour, or intense snow. Light rain might be acceptable to hike through; heavy downpour on a ridgeline with lightning risk is not. Understand the severity of incoming weather. Make risk assessment decisions based on actual precipitation intensity.
Weather Forecast 📅
Plan your trip with hourly and daily weather forecasts for your specific location. Know what conditions to expect before you start hiking.
Hourly Breakdown
Hour-by-hour forecast showing temperature, precipitation chance, cloud cover, and wind for the next 48 hours. Essential for day hikes where conditions might change multiple times. Know exactly when the best weather window is. Plan your start time based on forecast peaks. Understand the morning conditions before dawn hikes.
Daily Summary
7-day forecast showing high/low temperatures, precipitation chance, and weather icons. Plan multi-day backpacking trips by identifying the best weather windows. Schedule summit attempts for clear forecast days. Avoid trips when bad weather is predicted throughout the forecast period.
Elevation-Specific Forecasts
Separate forecasts for different elevation bands. Mountain weather changes dramatically with altitude. Get the forecast for your specific elevation rather than trusting valley forecasts. 50°F in the valley doesn't mean 50°F at 10,000 feet. Know the actual conditions you'll experience, not theoretical weather 5,000 feet below.
Wind Data 💨
Wind is a critical safety factor for exposed hiking, ridge traverses, and alpine terrain. Trail Map GPS gives you detailed wind information.
Wind Speed 💨
Current and forecasted wind speed in mph or kph. Understand wind exposure levels: 0-10 mph is calm, 10-20 mph is noticeable, 20-30 mph is strong, 30+ mph is dangerous on ridges. Know if wind will make hiking difficult, whether you need wind-resistant clothing, or if wind speeds are high enough to reconsider your route entirely.
Wind Direction 🧭
Wind direction shows which way the wind is blowing (which side of the ridge gets the headwind, which side is sheltered). Critical for choosing your route. A north-facing ridge might be brutal in north wind, but protected if the wind is from the south. Understanding wind direction helps you select the optimal route.
Gust Information
Peak wind gusts give you worst-case scenarios. Sustained 20 mph wind with 35 mph gusts is more dangerous than steady 20 mph wind. Gusts can knock hikers off balance or make footing unreliable. Plan ridge traverses when gusts are within safe limits. If gusts are forecast at 40+ mph, consider postponing exposed hiking.
Sun & Moon Information 🌙
Plan hikes based on daylight and moonlight. Know exactly when the sun rises and sets, when moonrise and moonset occur, and the current moon phase.
Sunrise & Sunset Times ⛅
Exact times for sunrise and sunset at your specific location (accounting for elevation and terrain shadows). Essential for planning hikes to maximize daylight or to summit at sunrise. Know the absolute deadline for your descent to avoid hiking in the dark. Different elevations have different sunset times—know your specific time, not the valley time.
Moonrise & Moonset 🌙
When the moon rises and sets allows you to plan night hikes using moonlight. A full moon provides significant natural light—great for mountain biking or hiking. A new moon means complete darkness—headlamps required. Know the exact time the moon appears above the horizon and when it sets. Plan night photography sessions for moonrise over mountains.
Moon Phase 🌕
Current moon phase shows how much moonlight you'll get during night hikes. Full moon = bright nights (maybe even need sunglasses). Half moon = moderate light. New moon = almost complete darkness. Waning gibbous = 75% moon setting after dark, so plenty of evening light. Plan night hikes when moon phases favor your schedule.
Civil Twilight Times 🌅
Twilight (period when sun is below horizon but light remains) extends safe hiking time beyond sunset. Know the actual end of civil twilight when you absolutely need artificial light. Many hikers maximize this twilight period for evening hikes. Civil twilight to official sunset can extend daylight by 20-40 minutes depending on latitude and season.
Elevation & Temperature Data 📊
Understand how elevation and temperature interact in mountain weather. Critical for choosing appropriate clothing and managing altitude exposure.
Current Altitude 🏔️
Your current elevation above sea level displayed in real-time. Barometric pressure sensor provides accuracy that's independent of GPS (which can be inaccurate for altitude). Essential for knowing how high you've climbed and managing altitude-related effects. Compare your current altitude to planned elevations.
Elevation Gain & Loss 📈
Total elevation climbed and descended displayed in real-time. Cumulative elevation gain is the best indicator of trip difficulty—more accurate than distance. Understand how much steep climbing you've already done and how much remains. Climb rate (feet per hour) helps estimate arrival times on steep sections.
Temperature Data 🌡️
Current temperature at your exact location, displayed in Fahrenheit or Celsius. Temperature drops approximately 3-5°F per 1,000 feet of elevation gain. Weather forecast gives temperatures for 10,000 feet elevation; you're at 6,000 feet, so actual temperature is warmer. Temperature affects clothing choices and water needs. Know the real conditions you'll experience, not forecast temperatures for different elevations.
Dew Point & Humidity
Dew point and humidity levels show moisture in the air. High dew point means feels-like temperature is warmer than actual (muggy conditions). Low dew point means water evaporates quickly from skin (dry conditions, higher sun exposure risk). Helps you understand comfort levels and plan hydration needs.
Why Weather Matters on the Trail 🧭
Weather is the most variable element of trail safety. Mountains create their own weather systems that differ from valley conditions. Afternoon thunderstorms, sudden fog, snow at altitude, wind on ridges—weather changes faster in mountains than anywhere else. Trail Map GPS gives you real-time, location-specific weather data so you make informed decisions. See an approaching storm on radar? Descend. Wind forecast showing unsafe gusts? Take a different route. Temperature unusually cold? Bring extra layers. Weather data is survival data. Make decisions based on facts, not guesses.
