Weather vs. Climate: What's the Difference?
The difference is time. Weather is what the atmosphere is doing right now or over a few days — today's rain, this week's heatwave. Climate is the average of that weather over decades, describing what a place is typically like. As the saying goes: climate is what you expect; weather is what you get.

Which should you use?
Weather
You're talking about weather when you mean the immediate, changeable conditions — temperature, rain, wind — at a specific place and time.
Climate
You're talking about climate when you mean the long-run average — what the seasons and typical conditions of a region are like over many years.
Frequently asked questions
- What's a simple way to remember the difference?
- 'Climate is what you expect; weather is what you get.' Climate tells you to pack for a generally cold country; weather tells you whether it's snowing today.
- Does a cold day disprove climate change?
- No. A single cold day is weather; climate change is about long-term shifts in averages. Short-term weather always varies, even as the climate warms overall.
- How long does weather have to last to become climate?
- Climate is typically measured over 30 years or more. It's the statistical average of weather, not any single stretch of days or seasons.
