Weather & Seasons
What is the difference between weather and climate?
The short answer
Weather describes short-term conditions such as rain, wind and temperature. Climate describes typical conditions and how often they occur over many years. Researchers use long measurement records, often thirty-year periods. One cold day therefore tells us little about a climate trend.
See how it works
Arrows show a direction or change. Sizes and distances are simplified. Read in order; each explanation belongs to the picture above it.
1. Observe today
We can measure temperature, watch clouds and notice wind today. These describe weather at a particular place and time.
2. Collect long records
Many comparable measurements are collected over long periods. A full picture needs different seasons and years, not one especially warm week.
3. Compare patterns
Researchers compare average temperatures, rainfall and how often hot days occur. Climate does not mean the same weather happens every day.
4. Separate timescales
A winter day can be cold while the long-term average temperature rises. A daily observation and a long-term trend answer different questions.
An imagined Wusel scene
Puschel and Flauschi investigate
Puschel takes one rain card to describe a whole summer. Flauschi shows the long museum row of different observations. He adds his single card: an important observation, but not yet a climate conclusion.
Word help
- Measurement record
- Related measurements arranged in time order.
- Average
- A summary value, not a description of every single day.
Your activity
Keep a weather diary for a few days. Compare them and call it a short weather observation. For climate, also use genuine long records from weather services, not your small collection alone.
Quiz: understand the idea
What does “It is raining here today” describe?
Choose a), b) or c), then explain your choice.
- a)Weather at this place.
- b)The typical rainfall over many years.
- c)The long-term frequency of rainy days.
Show the explanation
Correct: a): Weather at this place.
It describes one place and day. Climate requires much longer comparable records.
Try a new example
A region is warming over the long term, but it snows today. Can both happen?
Choose a), b) or c), then explain your choice.
- a)No, one snowy day disproves any long-term warming.
- b)Yes, individual cold days can still occur.
- c)No, a warmer climate means winter days cannot occur anywhere.
Show the explanation
Correct: b): Yes, individual cold days can still occur.
Climate describes long-term distributions. Individual days need not match the average.

More to discover
Why often thirty years?
Weather services use agreed long reference periods, often thirty years, for climate comparisons. This does not mean climate change can start only on a thirtieth anniversary. Other long records also help investigate change.
