Swedish Weather Precision, Now in Your Pocket

Stop guessing and start knowing. Klart.se transforms the daily weather check from a vague hope into a data-driven certainty. No more misleading icons or generic forecasts. This app delivers hyper-local, real-time weather intelligence sourced directly from Sweden’s most trusted meteorological service. Whether you’re planning a sailing trip in Stockholm or a hike in Jämtland, you get the exact wind, precipitation, and temperature data you need to make informed decisions.

Core Forecasting Tools & Data Layers

Klart.se is built around a suite of professional-grade weather tools, each designed to answer a specific question. The app pulls from multiple high-resolution models, not just one, to give you the most accurate picture possible.

• Multi-Model 10-Day Forecast: Compare forecasts from ECMWF, GFS, and AROME side-by-side. See the spread between models to gauge forecast confidence. Toggle between temperature, precipitation, wind speed, and wind direction in a single scrollable timeline.
• Interactive Wind & Rain Radar: Watch live precipitation and wind fields sweep across a map of Scandinavia. Use pinch-to-zoom to focus on your exact location. The radar updates every 10 minutes, showing movement and intensity with a color-coded legend.
• Hourly Wind & Gust Charts: For sailors, kite-surfers, and drone pilots. See predicted wind speed, gust strength, and direction plotted on a clear, hour-by-hour graph. The app highlights the peak wind window for your day.
• Precipitation Type & Amount: No more ambiguity. The app clearly distinguishes between rain, snow, sleet, and hail. See the expected accumulation in millimeters or centimeters, with a probability percentage for each hour.
• Sunrise, Sunset & UV Index: Plan photography, outdoor events, or gardening. The app provides exact solar times for your GPS location, plus a UV index forecast for skin safety.

Key Advantages Over Generic Weather Apps

• Hyper-Local Swedish Data: Uses SMHI and local observation stations, not just global satellites. This means more accurate forecasts for the unique coastal, mountain, and inland microclimates of Sweden.
• Clean, Ad-Light Interface: The design prioritizes data readability. No auto-playing video ads. No cluttered widgets. Your forecast is always one tap away.
• Offline Forecast Access: Download your 10-day forecast for a specific location while on WiFi. View it later without mobile data, perfect for mountain cabins or ferries with poor reception.
• Customizable Notification Alerts: Set alerts for rain start, heavy wind, or temperature thresholds. Get a push notification only when conditions change significantly, not every hour.

Heads up: you'll need a stable internet connection for live radar and model updates. The offline forecast feature is a great backup, but real-time data requires WiFi or mobile data. Some advanced model comparisons and extended forecasts may require a subscription to Klart Premium.
