A cloud chart is a visual guide that identifies cloud types by their appearance and altitude, helping you read the sky and anticipate weather changes. It is a practical reference for anyone living along the south coast or inland around Southampton.
How to use a cloud chart to forecast local weather
Different clouds bring different weather. A word cloud chart labels each type – from wispy cirrus to towering cumulonimbus – and links them to conditions such as rain, drizzle or fair spells. In Southampton, spotting low stratus often means a damp day over the Solent, while cumulus building inland can signal afternoon showers. Many observers keep a cloud chart poster on their wall for quick reference, and a printable cloud chart is handy for walks in the New Forest or along the coast. For the latest conditions, see our Southampton weather hub.
Where can I download a cloud chart PDF or get a poster?
The Met Office provides free cloud chart PDFs for printing. Many UK education suppliers also sell laminated cloud chart posters. A printable cloud chart is ideal for scout groups, classrooms or simply keeping in your car for spotting clouds over the Hampshire countryside.
How do I identify a cumulonimbus on a cloud chart?
Look for tall, dense clouds with a flat, anvil-shaped top. On most cloud charts it appears in the vertical development section, often labelled with lightning or heavy rain symbols. In Southampton, these clouds typically arrive with cold fronts from the west.
What does a cloud chart tell you about the coming weather?
It links cloud type to likely conditions. For instance, altocumulus often precedes a warm front, while cirrostratus can mean rain within 12–24 hours. Paired with our 10 day forecast, it gives a clearer picture for your plans around Southampton.
