March 21st: Autumn starts
June 21st: Winter starts
September 21st: Spring starts
December 21st: Summer starts
In the Northern Hemisphere, winter is from December to March, spring is from March to June, summer is from June to September, and autumn is from September to December.
July
The seasons occur therein the same order as in the north. The difference is that the seasonsare offset by two. Winter and summer occur together, one of them in each of the hemispheres. The same holds for spring and autumn.
The seasons we experience on Earth, where we see more daylight in the summer and less in the winter, come about due to the tilt in the earths axis. This tilt of 23.5° to the horizontal means that during its progression around the sun in one year, the northern hemisphere will `lean` towards the sun more at one part of the cycle, giving rise to summer months for the northern hemisphere and winter months for the southern hemisphere. Six months later, with the earth on the other side of the sun, the tilt causes the northern hemisphere to be less exposed to the sun, tilting away from it. This gives winter for the northern hemisphere (less daylight hours and lower sun during the day) and summer for the summer hemisphere.

Lets start with the Earth at a zero degree tilt both in the Northern Hemisphere and in the Southern Hemisphere. This is called the equinox, because neither hemisphere is tilting towards the sun. Now as the Northern Hemisphere tilts towards the sun at a tilt of 23.5 degrees which actually varies over time, but for this explanation lets just say 23.5 degrees. When the Northern Hemisphere reaches this tilt towards the sun, the Northern Hemisphere has summer, while the Southern Hemisphere has winter, because the Southern Hemisphere is tilted away from the sun at 23.5 degrees. The opposite case is true for when the Northern Hemisphere has winter and the Southern Hemisphere has summer.
The seasons are reversed. When it is spring or summer in the northern hemisphere, it is the autumn (fall) or the winter in Australia. This is caused by the northern part of the world being tipped the opposite way (towards or away) from the sun to Australia. The seasons in Australia and other countries in the Southern Hemisphere are reversed from those in the Northern Hemisphere. When it is summer in the Southern Hemisphere, it is winter in the Northern Hemisphere, and so forth. For example, the Australian summer starts in December, while winter begins in July.
Yes.
Seasons in the northern hemisphere occur at opposite times to those in the southern hemisphere. For example, when it is winter in the southern hemisphere, it is summer in the northern hemisphere.
Christmas would occur in winter in the Northern Hemisphere around the globe. In the Southern Hemisphere Christmas would occur in the summer as their seasons are opposite to the Northern Hemisphere.
Spring the summer then fall then winter for the northern hemisphere and opposite for the southern hemisphere.
As London is in the Northern Hemisphere, summer is (roughly) from June to August, fall is September to November, winter is December to February, and spring is from March to May. This is the same for all countries in the Northern Hemisphere.

when is the month for hurricane to occur in the northern hemisphere?
The Northern Lights occur in the northern hemisphere, in the ionosphere, the highest level of the atmosphere.
For societies that measure the passage of a year in the same system of months, the months occur at the same times worldwide. But the seasons are opposite for places in the northern hemisphere (such as the U.S.) and places in the southern hemisphere (such as Argentina). So although June in the U.S. is June in Argentina, June is summer in the U.S. and winter in Argentina. This is because the Earth's axis is tilted, so when the northern hemisphere is tilted toward the sun the southern is tilted away, and vice-versa.

Ozone depletion does not occur more over the northern hemisphere than anywhere else. More people with money for instrumentation, access to publication channels, and over-the-pole aircraft flights occur in the northern hemisphere.
