The longest day of the year, known as the summer solstice, is celebrated throughout the UK every year. It is also the day that the Earth's North pole is tilted closest to the sun, resulting in the longest day of the year in terms of daylight hours for those living in the northern hemisphere.

We have hot summers and cold winters because of the tilt of the Earth's axis. The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. The Earth's movement around the sun causes the seasons.
Learning about the seasons helps children understand the passage of time and teaches them about change. While some seasonal changes are more obvious (like changes in the weather), there are many important subtle differences related to each season, like changes in the type of food that is available.
During the summer, the sun's rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.
Due to high temperature and the surrounding bodies of water, the Philippines has a high relative humidity. Using temperature and rainfall as bases, the climate of the country can be divided into two major seasons: (1) the rainy season, from June to November; and (2) the dry season, from December to May.
Winter is good for the world around us. Many plants need shorter days and low temperatures to become dormant. This way plants can store up energy for new growth. But maybe the most important reason we need winter is because of the way the Earth is tilted.
Seasons are caused because of the Earth's changing relationship to the Sun. The Earth travels around the Sun, called an orbit, once a year or every 365 days. As the Earth orbits the Sun, the amount of sunlight each location on the planet gets every day changes slightly. This change causes the seasons.
Here Are 6 Countries Where Christmas Falls in Summer Instead of Winter
- Australia. Australia falls in the southern hemisphere which means, its winter is in June-July while December-January is peak summer season.
- New Zealand.
- Bolivia.
- South Africa.
- Argentina.
- Madagascar.
In the summer, days feel longer because the Sun rises earlier in the morning and sets later at night. The day that the Earth's North Pole is tilted closest to the sun is called the summer solstice. This is the longest day (most daylight hours) of the year for people living in the northern hemisphere.
TEHRAN (Tasnim) – Iran is one of the only countries in the world which has the complete four seasons.
Winter generally runs from November to March - though you can expect this to run longer during some years - and is characterized with cold weather, rain, sometimes snow and fog. Winter days in the UK the days are short and nights are long, with the sun rising at about 7 or 8am and setting at about 4 pm.
The UK gets on average 23.7 days of snowfall or sleet a year (1981 - 2010). Most of this is snow falling on higher ground where temperatures are lower, as can be seen on the maps below.
There are no official definitions of the duration of spring, summer, autumn and winter
| Date | In UK |
|---|
| March 20 at 09:37 UTC | Vernal (Spring) equinox |
| June 21 at 04:32 BST | Summer solstice |
| September 22 at 20:21 BST | Autumnal equinox |
| December 21 at 15:59 UTC | Winter solstice |
Australia's seasons are at opposite times to those in the northern hemisphere. December to February is summer; March to May is autumn; June to August is winter; and September to November is spring.
On the day the summer solstice occurs, we receive the most hours of daylight and the shortest night due to the position of the Earth in relation to the sun. For many, it marks the end of spring and the start of summer which will then end with the autumn equinox.
The best time to visit London is March through May when the temperatures are mild and the city's parks are green and blooming. However, late spring – along with summer – is also prime tourist season, and hotel and flight prices reflect the surge.
This year, astronomical spring began on 20 March 2021 and ended on 21 June 2021.
