Weather symbols and icons used in the


When using the Windy app, you see a large number of weather symbols and icons. The meaning of most of them is intuitive, but to understand some of them you need to know exactly what they mean. This guide will help you with that, as well as just navigate through all the variety of symbols.

Weather symbols (icons) of the general weather conditions

There are a total of 13 basic symbols (from left to rignt):

Sunny at daytime

A clear sunny day without clouds, which every outdoor enthusiast dreams of. In clear weather the view of the horizon is better, it is further visible from the tops of mountains. At the same time, clear weather is considered worse for outdoor photography, especially the sun in the middle of the day, so the photographers love the clouds.

Partly cloudy

The sky is covered with clouds, but not the whole sky, just a part of it. There may be more clouds than clear skies, or vice versa, or about the same.

Cloudy (Overcast)

The sky is completely clouded. Usually, it is an overcast day, although in different parts of the world, where the weather changes more frequently, even fully overcast skies can become clear in a matter of minutes.

Cloudy (Overcast) weather symbol /

Light rain

The weather with light rain when the sky is completely covered with clouds. Light rain is a rain with least 0.1 mm/h of precipitation.

Overcast weather with rain. Rain is 0.5 to 1 mm/h of precipitation.

Heavy rain

Overcast weather with heavy rain compared to the previous two conditions. Heavy rain means at least 1 mm of precipitation in an hour. But usually more.

Light sleet

Sleet is a mixture of snow and rain. One can change into the other or happen at the same time. The precipitation values for light sleet are the same as for light rain.

Light snow

Small ice crystals that fall from the sky. The values for light snow are the same as for light rain and light sleet.

It is snowing quite heavily — that is, more snow is falling than when you see the previous icon — and usually for several hours or more. Again, the numbers are the same.

Snow weather symbol /

Heavy snow

A heavy snowfall, which can also usually be quite long in time. In the Alps, for example, snowfalls can last up to 24 hours in a row or more. A month's worth of precipitation can fall in a day, blocking traffic on mountain passes or even a whole city. So now you know what do different snow signs mean in weather app.

Partly cloudy at night

Overcast at night. There may be more or fewer clouds or clear skies.

Clear sky at night

There are no clouds in the sky at all — it is completely clear like during the sunny day in the first icon from out list, or there are very few clouds in the sky.

Additional weather symbols and icons

In addition to the basic weather signs of the general weather conditions, there are some important signs in the app that explain different states of nature. To see them, select different weather profiles. For example, in the Fishing Pro Weather Profile, you can see five additional useful parameters for anyone who is into fishing. Let's take Channel Islands National Park as an example:
