Where I live, near Boston, the weather today is bad. We are having a blizzard. We have had about 20 cm. of snow so far and it is going to keep snowing until midnight. The temperature is -10°C and the wind is blowing a 40 km/hr. The climate where I live is classified as a "humid continental climate." Its location near the coast moderates temperatures, but makes it prone to storms called "nor'easters." In January the average temperature is about 0°C. The climate in Florida is warmer and nicer, but despite its wonderful climate, Florida can have bad weather: hurricanes, thunderstorms, and tornadoes. (The word "weather" can, however, CAN be used to mean "climate." Song lyrics say: "I'm going where the sun keeps shining Through the pouring rain Going to where the weather suits my clothes..." The lyricist, Nilsson, could have used either the word "weather" or "climate" but chose to use "weather.")

"Climate" is a very big-picture long-term description of weather patterns. There are technical terms that describe climates, but they are also described in terms like "very cold winters, hot summers, moderate precipitation throughout the year." "Weather" is what happens in a shorter term, from right now to many years. You can say" the weather today is rainy", "the weather this year has been hot", "the weather over the past 10 years has been hotter than long term averages." You wouldn't use "climate" in any if these cases.

Weather is simply how conditions appear at a particular time, such as whether it is cold or warm, dry or wet, sunny or cloudy. Climate is a much 'bigger picture', taking into account year-round conditions, long-term changes, and factors such as geographical position, sea currents and so on.
