"Climate is a measure of the average pattern of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate is different than weather, in that weather only describes the short-term conditions of these variables in a given region."
The answers received so far are correct, as far as they go, but I don't think that Wikipedia went far enough. Climate is more than the average weather conditions. The extremes are probably more important than the average. To explain by an analogy, if you had one foot submerged in a bucket of ice and the other submerged in scalding water, on the average, you would be comfortable. In more appropriate (to the question) terms, you can't have a tropical climate if there are going to be killing frosts in the area. That's why the USDA climate zones are based on the low temperatures for a region, not the average ones.
Climate is weather trends averages etc.
Weather is transitory. A thunderstorm is weather, no matter its intensity.
How frequently you are gets thunderstorms is more climate related.
Daily High or low temps are weather. Average daily high's and daily low's helps to define climate.
How much rain you get in a storm or a given week is weather. Average annual rainfall is more climate.
Hope this helps.
It could be the fact that weather is a daily or a weekly occurence over a large area or a specialized area.
climate is the effects of the weather over a season such as "The winter season, or the "The summer season which includes the weather over a period of 3-4 months or a quarter of time.
Weather refers to a short time, single location. Climate refers to longer periods of time over larger locations.
