Have you ever wondered what the weather is like in other places around the world? Today, I’d like to talk about
the changing seasons in my city. The winter season usually begins in December and ends in early March. The
coldest month is January, and temperatures can drop below freezing for most of this month. The city usually
averages about 30 inches of snow during this 3-month period. Occasionally, we have snow storms that can drop
a foot of snow in a very short period of time. Spring usually arrives in late March, it’s a beautiful season
because the flowers start to bloom. It is sometimes windy, and this is great for flying kites. People in my city
often like to go on picnics, stroll though parks, and play outdoor games. Summer starts in June and it’s very dry
with little rain throughout the season. Fortunately, the weather is very dry with low humidity, so it is real
pleasant even on hot days. And finally, summer changes to fall in late September when the weather cools off,
and the trees begin to change colors. A lot of people enjoy driving into the mountains and viewing the fall
colors.
