ICAO Weather Picture Description – ICAO Aviation English Weather Picture Practice

ICAO Weather Picture Description

ICAO Weather Picture Description helps pilots and aviation professionals practise how to describe weather situations clearly in the ICAO speaking test. In this task, you may need to describe clouds, rain, fog, wind, snow, storms, poor visibility, runway conditions and the possible effect on flight operations.

What is ICAO Weather Picture Description?

In this kind of task, you look at a weather-related aviation image and explain what you can see. The examiner wants to hear clear, accurate and organized speech. You should not only name the weather. You should also explain its operational effect.

You may need to describe:

heavy rain
fog or low visibility
snow or ice
strong wind
crosswind conditions
thunderstorms
lightning near the airport
wet or contaminated runway surfaces
de-icing activity
delays, diversions or holding

Why weather description is important in ICAO speaking

Weather is one of the most important topics in aviation communication. Pilots must be able to describe weather conditions precisely and explain how they affect aircraft operations, safety and decision-making.

The examiner may listen for:

clear weather vocabulary
good pronunciation
logical structure
ability to describe cause and effect
correct use of speculation
continuous and confident speech

Simple structure for weather picture description

A practical way to answer is to move from the overall weather picture to the operational details and then to the consequences.

Suggested structure

1. General scene: describe the airport or flight situation
2. Weather conditions: explain the weather clearly
3. Operational effect: say how the weather affects aircraft or airport activity
4. Likely outcome: explain what may happen next

Useful opening phrases

This picture shows poor weather conditions at an airport.
The weather in this image appears to be severe.
It looks like visibility is very limited due to fog.
The runway seems wet and the aircraft may be affected by the conditions.
This appears to be a weather-related operational situation.

Useful ICAO weather vocabulary

Cloud and visibility

low cloud
overcast sky
reduced visibility
poor visibility
dense fog
mist
low ceiling

Rain, snow and storm conditions

heavy rain
strong winds
gusty conditions
crosswind
thunderstorm activity
lightning
snowfall
icy surface
slippery runway

Operational impact language

The weather may delay departures.
The aircraft could experience turbulence.
The crew may need to divert.
The runway might be contaminated.
Ground handling may be restricted.
De-icing may be necessary before departure.
The approach may be more difficult due to low visibility.

Common weather picture situations

Typical ICAO weather picture topics

aircraft landing in heavy rain
fog around the runway or taxiway
snow at the airport
de-icing before departure
thunderstorm near the airport
strong crosswind during landing
airport vehicles operating in bad weather
wet runway and braking concerns

Example weather picture description

This picture shows an aircraft at an airport during poor weather conditions. The sky is very dark and cloudy, and it appears to be raining heavily. Visibility seems reduced, so the crew may have difficulty during approach or taxiing. The runway surface looks wet, which could affect braking performance. There may also be strong winds or gusts in this situation, especially if a storm is approaching. In my opinion, the airport operations may be delayed, and some flights could be diverted if the weather becomes worse. The crew will need to monitor the conditions carefully and follow the appropriate safety procedures.

Language for cautious description

In ICAO speaking, it is often useful to describe carefully when you are not completely sure. This sounds natural and professional.

Useful phrases

It appears to be raining heavily.
There seems to be low visibility.
The runway may be wet or slippery.
It looks as if a storm is approaching.
The aircraft might face a difficult landing.
This could lead to a delay or diversion.

Mistakes to avoid

only listing weather words without explanation
speaking too briefly
forgetting the effect on flight operations
using very long and complicated sentences with errors
repeating the same words too often
ignoring important visible details such as runway condition or visibility

Important: In ICAO weather picture tasks, it is better to speak simply and clearly than to use complicated language. The key point is to explain the weather and its effect on aviation operations in a logical way.
