Type a city name above and press + Add City to see live weather.
SunorSnow shows live conditions and short-range forecasts for up to six cities side by side, so you can compare places at a glance instead of opening six tabs. It is free, needs no account, and works on phones as well as desktops.
Start typing a city name in the search box, pick the right match from the suggestions (they include the region and country, which helps with places like Paris, Texas), then press “+ Add City”.
Each city gets its own card with the local time, today’s high and low, current conditions, the “feels like” temperature, humidity, wind speed, pressure, UV index and a colour-coded air-quality bar.
Swipe the 24-hour strip on each card for hour-by-hour temperatures (the current hour is highlighted), and check the three-day outlook with highs, lows, the chance of rain and the strongest wind expected each day.
Use the °C / °F buttons to change temperature, and the wind setting for km/h or mph. Your city list and units are remembered on this device the next time you visit.
Live data comes from WeatherAPI.com and refreshes each time a card loads. For long-term averages — how hot July usually is, or which month is wettest — use our city climate guides instead.
Understanding the weather is more than looking at a cloud — it's about data, physics, and global patterns. At SunorSnow, we believe understanding the "why" behind the weather helps you plan your life better.
Weather is the state of the atmosphere at a specific place and time, driven by four main ingredients:
Meteorologists use Numerical Weather Prediction (NWP). Supercomputers take data from satellites, weather balloons and ground stations and solve complex equations to see how air will move and change over the next few days.
You've likely seen "H" and "L" on weather maps:

The air temperature is measured in the shade. “Feels like” adjusts it for humidity in hot weather (heat index) and for wind in cold weather (wind chill), which is why 34°C in a humid city can feel above 40°C.
The probability that measurable rain or snow falls at that location during the period. A 40% chance does not mean it will rain 40% of the day; it means rain is possible but not certain, so check the hourly timeline.
Relative humidity is how close the air is to saturation. High humidity makes heat feel heavier because sweat evaporates more slowly; very low humidity dries skin and eyes.
The sustained wind speed now, and the strongest sustained wind expected on each forecast day. Gusts can be noticeably stronger than the average, especially near coasts and between tall buildings.
The strength of the sun’s ultraviolet radiation: 0–2 low, 3–5 moderate, 6–7 high, 8–10 very high, 11+ extreme. Sun protection is worth using from 3 upward, even on cool or hazy days.
A summary of pollutants such as fine particles (PM2.5) and ozone, on the US EPA scale: Good, Moderate, Unhealthy for sensitive groups, Unhealthy, Very unhealthy and Hazardous. The coloured bar on each card follows that scale.
Shown in millibars (mb), which are the same as hectopascals (hPa); the average at sea level is about 1013 hPa. Falling pressure often signals unsettled weather on the way, while rising pressure usually means conditions are improving.
Today’s high is the warmest temperature expected during the day, usually mid-afternoon; the low is the coolest, usually just before sunrise. A big gap between them is typical of dry, clear places such as desert cities.
Yes. The dashboard, the climate guides and the articles are free to use, with no sign-up. The site is supported by advertising.
Forecasts are updated as new observations arrive from satellites, weather balloons and ground stations. Short-range forecasts (one to three days) are the most reliable; beyond about a week, treat them as trends.
Weather apps use different data providers and different measuring points. A difference of one or two degrees between sources is normal, especially in large cities with hills or coastlines.
