Sundog Weather & Trends

Sundog tests its forecast against real weather stations near you, shows you the score, and sharpens the next forecast every day, tuned to your neighborhood, trailhead, or summit. A FORECAST THAT SHOWS ITS WORK See exactly how Sundog has been performing at your location: typical temperature error, rain hit rates, precipitation accuracy, and how reliability holds up from the next hour to the days ahead. So when Sundog calls for rain at 3pm, you can see exactly how its short-range rain forecasts have been performing at your location. PRECISION DOWN TO 1 KILOMETER Weather changes street to street across coastlines, valleys, ridge lines, and neighborhoods. Sundog resolves forecasts down to 1 kilometer, accounting for terrain, elevation, and how weather actually behaves around the spot you choose. BUILT FOR REAL TERRAIN In the mountains, switch between Valley, Mid-mountain, and Peak and watch the forecast recalculate at each elevation. See where rain turns to snow, where calm valley air becomes wind above tree-line, and how conditions shift as you climb. From city blocks to open plains to high alpine routes, Sundog is built for landscapes where weather changes fast and the difference matters. THE NEXT TWO HOURS, TO THE MINUTE When precipitation approaches, Sundog tracks it minute by minute: when it starts, how hard it hits, when it eases, and whether snow, hail, or lightning is riding along. Alerts give you a heads-up before the first drops arrive and when severe weather is headed your way. Animated radar lets you follow storms, severe weather, wind, wildfire smoke, and air quality as they develop. SEE THE DAY BEFORE IT UNFOLDS Follow temperature, precipitation, wind, and changing conditions through beautiful hourly charts and a detailed 14-day outlook.
