Weather Symbols Explained: Names, Icons, and Their Meanings

Weather symbols make it easier to understand forecasts at a quick glance. From a bright sun icon and fluffy clouds to rain, thunderstorms, snow, fog, and strong winds, each symbol represents a specific weather condition. Learning weather symbols with names can help you read weather apps, forecast maps, news reports, and digital displays without confusion.

Different weather services may use slightly different designs, but the basic meanings are usually easy to recognize. A sun can indicate clear or sunny conditions, while a cloud may represent cloudy weather. Other symbols can show rain showers, thunderstorms, snow, freezing temperatures, fog, wind, and severe weather conditions. Knowing what these icons mean makes daily weather information much easier to understand.

In this complete guide, you’ll find common weather symbols with their names and meanings, along with simple explanations of what each icon represents. Whether you are checking tomorrow’s forecast, studying weather symbols for school, reading a weather map, or simply curious about those small icons on your phone, this guide will help you identify them quickly and confidently.

Weather Symbols With Names and Meanings

The following chart provides a quick reference to some of the most common weather symbols and their names.

The exact appearance of these icons can differ between weather services. A weather app may use a slightly different graphic for the same condition, but the general meaning is usually similar.

Common Weather Forecast Symbols Explained

Weather forecast symbols are designed to communicate the expected condition for a particular period. Understanding the most common icons can make forecasts much easier to read.

Sunny Symbol ☀️

The sun symbol represents sunny or clear weather. It generally means there is little cloud cover during the forecast period.

A sunny symbol does not automatically mean that temperatures will be high. A location can have clear skies and still experience cold temperatures, particularly during winter.

Mostly Sunny Symbol 🌤️

The mostly sunny symbol usually combines the sun with a small cloud. It indicates that sunny conditions are expected for much of the forecast period, although some clouds may be present.

This symbol is useful when the sky is expected to remain generally bright but not completely clear.

Partly Cloudy Symbol ⛅

The partly cloudy symbol shows the sun partly covered by a cloud. It means that both sunshine and clouds are expected.

Partly cloudy conditions can change throughout the day. The amount of cloud cover may increase or decrease depending on local weather conditions.

Mostly Cloudy Symbol 🌥️

A mostly cloudy symbol indicates that clouds are expected to dominate the sky, although some breaks in the clouds may occur.

It is different from a completely overcast forecast because occasional sunshine may still be possible.

Cloudy Symbol ☁️

The cloud symbol represents cloudy or overcast conditions. It generally means that clouds are expected to cover most or all of the visible sky.

Cloudy weather does not necessarily mean rain. A forecast can show a cloud symbol even when little or no precipitation is expected.

Rain Symbol 🌧️

The rain symbol usually shows a cloud with falling raindrops. It indicates that rainfall is expected during the forecast period.

Weather services may further describe rain as light, moderate, heavy, scattered, or continuous. The icon alone may not provide information about the exact amount of rainfall.

Sun and Rain Symbol 🌦️

The sun-and-rain symbol commonly represents showers or changing conditions in which sunshine and rainfall may occur during the same period.

It can be useful when rain is expected to be intermittent rather than continuous.

Thunderstorm Symbol ⛈️

The thunderstorm symbol commonly combines a cloud, rain, and a lightning bolt. It indicates the possibility or expectation of thunderstorms.

Thunderstorms can produce lightning, thunder, heavy rainfall, strong winds, and sometimes hail. Because conditions can change quickly during thunderstorms, official warnings should be followed when they are issued.

Lightning Symbol 🌩️

The lightning symbol indicates lightning or electrical storm activity. Some weather apps use it separately from the standard thunderstorm icon to emphasize lightning.

Lightning is associated with thunderstorms and can occur even when heavy rain is not directly over a particular location.

Snow Symbol ❄️

The snowflake symbol represents snowfall or snowy weather.

Snow forecasts can range from light snow to heavy snowfall. The symbol may also be used for snow showers, although some apps use a separate icon for intermittent snow.

Snow Showers Symbol 🌨️

A snow-showers icon indicates periods of snow that may start and stop rather than continuing throughout the forecast period.

This is different from a forecast for continuous snowfall because snow showers can be brief and localized.

Fog Symbol 🌫️

The fog symbol generally represents fog or very low visibility caused by tiny water droplets suspended near the ground.

Fog can affect driving, aviation, and other activities because it reduces visibility. The icon does not necessarily indicate that temperatures will be cold.

Wind Symbol 🌬️

The wind symbol indicates noticeable or strong winds. Weather services may display this icon alongside information about wind speed, direction, and gusts.

For more accurate information, check the numerical wind speed and direction rather than relying only on the icon.

Tornado Symbol 🌪️

The tornado symbol represents a tornado or tornado-related conditions.

Tornadoes are rotating columns of air that extend from thunderstorms toward the ground. When an official tornado warning is issued, people should follow local emergency guidance rather than relying only on a weather icon.

Weather Symbols for Different Types of Precipitation

Precipitation refers to water or ice that falls from the atmosphere to the Earth’s surface. Different types of precipitation have different symbols.

Rain

Rain consists of liquid water droplets falling from clouds. A cloud with raindrops is one of the most common precipitation symbols in weather forecasts.

Snow

Snow consists of ice crystals that form in cold atmospheric conditions and reach the ground as snowflakes. A snowflake is the most recognizable symbol for snowy weather.

Sleet

The term sleet can have different meanings depending on the country or weather service. In some regions, it refers to ice pellets, while other regions use the term for a mixture of rain and snow.

For this reason, it is useful to read the forecast description instead of interpreting the icon alone.

Freezing Rain

Freezing rain falls as liquid rain but freezes when it comes into contact with cold surfaces. Weather services may use a rain-and-ice style icon to represent this condition.

Freezing rain can create slippery roads and surfaces.

Hail

Hail consists of pieces or balls of ice produced in thunderstorms. It is different from snow because hail forms in strong convective storms rather than simply falling as snow from cold clouds.

A weather service may use an ice-pellet or storm icon to represent hail.

Weather Map Symbols and Their Meanings

Weather forecast icons are not the only symbols used to communicate weather information. Meteorologists also use specialized symbols on weather maps.

These symbols can show pressure systems, fronts, wind, cloud cover, and other atmospheric conditions.

High-Pressure Symbol

High-pressure areas are commonly marked with H on weather maps.

High pressure is associated with sinking air and, depending on the location and season, can be linked with more stable weather conditions.

Low-Pressure Symbol

Low-pressure areas are commonly marked with L.

Low-pressure systems are often associated with rising air, cloud development, and changing or unsettled weather. The exact weather depends on the system and surrounding atmospheric conditions.

Cold Front Symbol

A cold front is commonly represented by a line with triangles pointing in the direction of movement.

A cold front occurs when colder air advances and replaces warmer air.

Warm Front Symbol

A warm front is commonly represented by a line with semicircles pointing in the direction of movement.

It indicates advancing warmer air replacing colder air.

Stationary Front Symbol

A stationary front is represented using alternating symbols associated with cold and warm fronts on opposite sides of the line.

It indicates a boundary between air masses that is moving slowly or remains relatively stationary.

Occluded Front Symbol

An occluded front is commonly represented by a line containing alternating triangles and semicircles on the same side.

It forms when one front catches up with another front, combining characteristics of different air masses.

Wind Barbs

Wind barbs are specialized symbols used to show wind direction and speed on weather maps.

The staff points toward the direction from which the wind is coming, while the markings indicate wind speed according to the system’s scale.

Unlike a simple windy icon, a wind barb can provide detailed information about atmospheric wind conditions.

Difference Between Similar Weather Symbols

Some weather symbols look similar but represent different conditions. Knowing the difference can prevent confusion.

Sunny vs. Mostly Sunny

Sunny generally means clear skies with little cloud cover.

Mostly sunny means sunshine is expected for most of the period, but some cloud cover is present.

Partly Cloudy vs. Mostly Cloudy

Partly cloudy means there is a mixture of sunshine and clouds.

Mostly cloudy means clouds dominate the sky, with fewer periods of sunshine.

Cloudy vs. Rainy

Cloudy describes cloud cover and does not necessarily mean precipitation.

Rainy indicates that rain is expected.

Therefore, a cloudy day can remain dry, while a rainy forecast specifically indicates precipitation.

Rain vs. Thunderstorm

A rain symbol indicates rainfall.

A thunderstorm symbol indicates a storm that may include lightning and thunder, often accompanied by rain and sometimes strong winds or hail.

Snow vs. Snow Showers

Snow can indicate a more sustained period of snowfall.

Snow showers usually indicate intermittent or brief periods of snow.

The exact thresholds and terminology can vary between weather services.

Weather Symbols on Phones and Weather Apps

Weather icons are commonly displayed on smartphones, tablets, computers, and smartwatches.

Different apps may use different designs, so the same weather condition may not look identical everywhere.

For example, one app might represent partly cloudy conditions with a sun behind a cloud, while another may use a different graphic.

When interpreting an icon on a phone, look at the accompanying information, such as:

• Temperature
• Precipitation probability
• Wind speed
• Wind direction
• Humidity
• Weather description
• Hourly forecast
• Severe weather alerts

The icon provides a quick visual summary, while the numerical forecast gives additional detail.

Why Weather Symbols Are Important

Weather symbols make complex forecasts easier to understand. A visual icon can communicate a basic weather condition much faster than a paragraph of text.

They are especially useful for:

• Checking daily forecasts
• Planning outdoor activities
• Understanding weather apps
• Reading weather maps
• Following television forecasts
• Checking travel conditions
• Understanding precipitation forecasts
• Identifying changing weather conditions

However, symbols should be treated as a quick summary rather than a complete weather report. When conditions are potentially dangerous, official warnings and detailed forecast information are more important than the icon alone.

How to Read Weather Symbols Correctly

The best way to interpret a weather symbol is to consider it together with the rest of the forecast.

For example, a rain icon tells you that rain is expected, but it may not tell you whether rainfall will be light or heavy. Checking precipitation probability, expected rainfall amount, timing, and severe-weather alerts can provide a much clearer picture.

Similarly, a wind symbol indicates windy conditions, but wind speed and gust information are needed to understand how strong the wind may become.
