Weather by month puts your current temperatures and precipitation into a historical context. It compares actual weather to normals based on 30-year data.

From March to May, cool days and some rain alternate with the first heat waves in spring. In summer, hot and humid weather prevails from June to August.

Summer

Many people like to spend their time during summer because of the longer daylight hours. This allows people to be more active during the day, which can help them maintain a healthy lifestyle. During the warmer months, there are many enjoyable activities to share with loved ones.

The weather during this season is often warm and dry. There are fewer thunderstorms, but heat waves can occur in some places. The temperature can be slightly higher than in spring and fall, but cooler temperatures are also ordinary. In some areas, droughts can be a problem during this season.

The official beginning of summer in the United States falls on June 20 or 21, the summer solstice date. In contrast, the end of summer is marked by the autumnal equinox, which occurs on September 22 or 23. In other parts of the world, the summer season starts around May 5 with the Chinese solar term jieqi (Li Xia) and ends in August with the solar term liqiu (Li qiu – “establishment of autumn”).

Although being outdoors is a fun time, taking precautions in warm weather is essential. Excessive heat can be dangerous, especially for young children and older adults. People can also suffer from dehydration, heat cramps, and sunburn.

Winter

Winter is the season that typically occurs between December and March in New York City. It is also the coldest time of the year. During this time, it is common for temperatures to fall below freezing and even drop into single digits. It is common for snow to fall on most days this month.

The meteorological reckoning of winter starts in late November or early December and ends in late February or early March, depending on seasonal lag. This definition of winter differs from the ecological one but is similar in that it marks a period of biological dormancy that lasts until spring.

Climate normals are 30-year averages for weather variables like temperature and precipitation. These values are used to compare current weather conditions with the long-term averages. They are essential because they provide a reference point for how much warmer or cooler than usual a day is. This information can help us more confidently predict future Iceland weather by month conditions.

The warmest months of the year in New York are June and July, with an average daily high temperature above 76°F. During this time, it is possible to enjoy outdoor activities such as walking and biking along the waterfront. In January, New York’s average daily high is a cool 26°F. It’s best to bring a jacket and hat during this time as the Sun is out less often.

Spring

While astronomical seasons are determined by the Earth’s position relative to the sun, meteorological and climatological seasons are divided into three-month periods corresponding to average temperatures around the globe. Biological indicators, such as the blossoming of certain plant species or activities of specific animal species, also define the seasons.

Spring is all about new beginnings: warming temperatures, buds bursting from trees, birds returning to their breeding grounds. For many people, the arrival of spring signals a time to take advantage of the longer days by going outside and enjoying more temperate weather.

But spring isn’t without its hazards, such as floods and tornadoes. These are often caused by thunderstorms, which occur when warm, moist air collides with more relaxed, dry air. This type of weather is prevalent in the spring and summer when warm air moves up into the upper atmosphere from the tropics.

Springs have been essential to the world’s Indigenous cultures since time immemorial, serving as reliable water sources, places of healing and spiritual significance. However, these critical resources are threatened by climate change and growing human populations worldwide.

A recently published book in AGU’s Geophysical Monograph Series, Threats to Springs in a Changing World: Science and Policies for Protection, showcases research illustrating how spring quality has been compromised and strategies being used to preserve and protect these natural treasures.

Fall

Sandwiched between blazing summer and frigid winter, autumn, also known as fall in some regions of the world, marks the season when the weather starts to cool. During fall, trees change color before losing leaves due to decreasing temperatures. In many areas, this is a beautiful sight to see.

The Earth’s tilt and rotation as it orbits around the Sun are the reasons behind the changes in seasons. When the axis directly faces the Sun, the northern and southern hemispheres receive equal amounts of sunlight. This results in a hot summer in the North and a cold winter in the South. During the fall, the equinox occurs when the Sun is directly above the equator and evenly distributes its energy over the North and South.

Fall is also the time of college football, pumpkin spice lattes, and a general nip in the air. As temperatures cool, many people spend more time outdoors, playing sports, hiking, or raking up all those dead leaves that fall from the trees.

This can be a great way to exercise and increase our exposure to the natural world, providing health benefits. In addition, the onset of cooler weather makes it easier for some people with heat-related illnesses to enjoy outdoor activities without worrying about excessively high temperatures or hydration issues.
