Weather guide
Understanding a weather forecast means knowing how to read the numbers and symbols meteorologists use to describe the atmosphere. Meteoshark pulls data from the Open-Meteo service, which aggregates output from multiple national weather models and recombines it into a single, high-resolution forecast. The result is a balanced prediction that is often more reliable than any one model on its own.
Temperature is the most familiar element, but the value you feel on your skin — the apparent or “feels like” temperature — also accounts for wind and humidity. On a windy winter day, your body loses heat faster, so the wind chill drops well below the thermometer reading. On a humid summer afternoon, sweat evaporates more slowly, pushing the heat index above the actual air temperature.
Precipitation probability tells you how likely it is to rain at your location during a given hour or day, not how much rain will fall. A 70% chance means seven out of ten similar situations produce measurable precipitation. The rain radar animates the most recent satellite and ground-station frames so you can watch showers move in real time and estimate when they will reach you.
Wind speed and direction, atmospheric pressure, humidity, UV index, and air quality each describe a different facet of the sky. Reading them together gives you a complete picture: when pressure falls, rain often follows; when the UV index climbs, sun protection matters; when air quality drops, sensitive groups should limit outdoor effort. The glossary below explains the key terms so you can interpret every forecast with confidence.
Glossary
Atmosphere
Air Quality Index
A scale that describes how clean or polluted the air is and what health effects may be expected, based on pollutants such as PM2.5, PM10, ozone and nitrogen dioxide.
Temperature
Apparent temperature
The temperature your body actually feels, accounting for wind and humidity rather than the raw thermometer reading. Also called the 'feels like' temperature.
Precipitation
Precipitation probability
The chance, expressed as a percentage, that a measurable amount of rain or snow falls at your location during a given hour or day. It does not describe how much precipitation will fall.
Radar
Rain radar
A live map of precipitation built from radar and satellite observations, animated frame by frame so you can see where rain is falling and where it is moving.
Atmosphere
UV index
An international standard scale from 0 to 11+ that describes the strength of ultraviolet radiation from the sun at a given time and place.
Temperature
Wind chill
How cold the air feels on exposed skin when wind is factored in, expressed as a temperature lower than the actual air temperature.
