The website icimeteo.com allows users and visitors to track weather conditions in France in a clear, intuitive, and smooth way, different from what is found on other platforms. Here is an explanation of each weather data or value mentioned on the site:

Weather Icon
This is the graphical indicator showing the current general state of the sky: clear, partly cloudy, overcast, rainy, snowy, or stormy.

Temperature
This measures atmospheric heat as commonly understood, reflecting the agitation and movement of gas molecules in the air. A cold feeling begins below 18°C, and a warm feeling above 26°C. However, this is purely theoretical unless accompanied by the "feels-like temperature."

Feels-Like Temperature
This reflects our actual perception of the theoretical temperature, depending on other factors that can amplify or reduce its effect. Above 23°C, humidity affects heat perception and sweating. Below 17°C, wind increases the sensation of cold.

Humidity
This is a theoretical value reflecting the air's saturation with water vapor. Often used on websites and home weather devices, it does not reflect actual perception. Relative humidity, expressed as a percentage, varies with temperature. For example, 65% humidity at 19°C feels comfortable, but at 30°C, it becomes unbearable because humidity prevents the body from dissipating heat through sweating.

Dew Point
This is the theoretical temperature at which condensation (or dew) occurs based on humidity, atmospheric pressure, and temperature. Measured in Celsius, it reflects absolute humidity that directly affects our perception. Comfortable dew point values range from 10 to 16°C. Below this, air becomes dry, increasing cold sensations or causing skin and mucous irritation. Above 16°C, particularly at 20°C in summer heat, it intensifies the feeling of heat and sweating. The website shows the dew point on main tables via emojis next to humidity, on the top current measurements table, and on summary tables with exact numeric values.

Precipitation
This is the amount of rain collected after a shower in a 20.8 cm diameter gauge (according to the World Meteorological Organization standard), measured in millimeters. It is placed in an open area, away from buildings and trees, at a height of one to two meters.

Wind Speed and Direction
Wind speed, in kilometers per hour, is measured with a rotating anemometer driven by the wind, while the same device indicates wind direction.

Atmospheric Pressure
Unlike solids or liquids, gas pressure increases or decreases. Air around the Earth is subject to pressure forces that vary with altitude. The average standard sea-level pressure is 1013.25 hPa (hectopascals) or mb (millibars). Higher pressure indicates a high-pressure area, usually associated with clear, stable weather but also dry periods. Lower pressure signals a depression, often accompanied by precipitation, wind, and storms.

UV Index
The UV index is measured on a scale from 0 to 10 and above. Zero generally corresponds to evening or night with no sunlight. A 1–2 index indicates low UV radiation requiring no special precautions. Between 3 and 5, sunscreen, sunglasses, and a hat are recommended. Between 6 and 7, additional protection in the shade is essential. Between 7 and 10, all measures are mandatory. Above 11, it is preferable not to go outside unless absolutely necessary. UV intensity is not related to temperature. UV radiation peaks at the summer solstice on June 21, even if the temperature is moderate or cool. Wind or cloudy skies do not reduce UV strength. Higher altitude also increases UV exposure as thinner air filters radiation less effectively.
