Temperatures around the Earth can vary greatly depending on a number of factors such as geography, climate, time of day, and season.

At any given moment, temperatures can vary by hundreds of degrees Celsius between the hottest and coldest places on Earth. The coldest place on Earth is Antarctica, where temperatures can drop as low as -90°C (-130°F) in the winter. In contrast, the hottest place on Earth is the Lut Desert in Iran, where temperatures have reached up to 71°C (160°F) in the summer.

Additionally, temperature differences can also be observed between regions with different climate zones. For example, the temperature difference between the equator and the poles can be quite significant, with temperatures in tropical regions typically staying warm year-round while polar regions experience extreme cold during the winter months.

Overall, the temperature differences around the Earth can be quite large and vary depending on a wide range of factors.
Earth’s weather and temperature is constantly changing. Our website stores the warmest and coolest global temperatures every hour. Those locations that make it into the hottest and coldest in the last seven days are displayed on this page. The temperatures are sorted from hottest to coldest.

Weather vs Climate

Weather is what you see or experience outside at any time on any day.

So, for example, it may be 75° degrees and sunny or it could be 20° degrees with heavy snow. That’s what the weather is. We can discuss long term forecasts of what the weather will be, or what happened last year in this month. It’s all weather, but it is not the same as climate.

How is Weather different than Climate?

Climate is the average of “weather” over an accepted period of time which is normally 30 years or more. When people discuss changing climate they are describing changes from the normal averages.

What causes the Weather?

The two most important influences in weather are the Sun and Earth’s atmosphere. The Sun heats objects on Earth and this heat is absorbed by the atmosphere. The absorption may include water vapor which creates the clouds and can attribute to rain and other types of precipitation. Other factors ( variables ) such as high and low pressure effect the winds and storm systems.

What Exactly are Jet Streams?

A sketch of a couple of jet streams in northern and southern hemispheres

Jet Streams affect our winds down at the surface

As the jet streams move around the globe they rise and fall in altitude. The wind speeds high up in the mountains can be much stronger than in lower surrounding areas. This is due to the jet streams can be low enough to to be blowing through the mountain ranges. With dramatic changes in air pressure the jet streams altitude can change drastically. When wind speeds are above 50-mph the jet stream may only be a mile above the earth surface.

How many jet streams are there?

There are normally 4 jet streams traveling around the earth at the same time, 2 are in the southern hemisphere and 2 in the northern hemisphere. One of them is at latitude of approximately 60-degrees while the second is around the 30-degree latitude. The jet streams shift north or south with the changing seasons.

Why do the jet streams travel from west to east?

Because the Earth is rotating in that direction and surface tension is pulling the wind along in that general direction. The winds ave a tendency to want to move towards the cold poles of the globe.

How fast is the Earth rotating?

At the equator the earth rotates 1000 miles per hour based on 24,000 mile circumference and one rotation per day. On a perfectly still ( no wind ) day the air is also moving along at the same rate as the earth. At 45 degrees latitude, north or south, the earth is spinning in the 707 mph range ( because the distance at that latitude around the globe is shorter ).

How fast is the jet stream traveling?

The jet stream moves along at over 100 mph and even as high as 275 mph. For comparison, F-4 tornado wind speeds are 207 to 260 mph, F-5 are 261 to 318 mph. At the equator the jet stream is moving more slowly and picks up speed with the increase in latitude because as mentioned before, the distance around the globe is shorter, yet, the wind maintains it momentum and must travel faster to cover the same distance as at the equator. Wind speeds also increase with the increase of difference from low to high temperatures. The largest gradient between temperatures is at latitudes of 30-degrees and 60-degrees (north and south ) and therefore the wind speeds will be higher in these areas. Each of these ever changing factors contribute to the wind speed.

Jet Streams do not flow straight around the planet.

The jet streams stay in the boundaries between hot and cold air zones similar to a river staying within it’s banks. The shape of these air rivers is constantly changing as high pressure (cold) and low pressure (hot) cells are actively forming and collapsing. The jet streams general latitude changes as the seasons change, with winter having the strongest winds. The jet streams follow the sun’s latitude changes, ie as the sun moves south after the Summer Equinox, the jet streams will also. As earth enters summer the jet stream is moved farther towards the pole. In winter the jet stream moves closer to the equator.

In summary:

Jet streams are a constant phenomena whether we see them or not. They are constantly racing around the earth trying to find equilibrium between high and low pressure while the earth’s rotation is pulling them along from the west to the east. If the jet stream elevation is low enough we can have very strong winds, even up 100 mph. Jet streams top speed is around 275 mph, that’s in F-5 tornado wind speeds.

The summers in the Northern Hemisphere are generally hotter than in the Southern Hemisphere for several reasons, including:

Tilt of the Earth: The Earth is tilted on its axis, which means that during the Northern Hemisphere summer, the North Pole is tilted towards the Sun. This means that the Northern Hemisphere receives more direct sunlight and experiences longer days, which results in warmer temperatures.
Landmass: The Northern Hemisphere has more landmass than the Southern Hemisphere, which means that it heats up more quickly and retains heat for longer periods of time. This results in higher temperatures during the summer months.
Ocean Currents: The ocean currents in the Northern Hemisphere are warmer than those in the Southern Hemisphere, which also contributes to the warmer temperatures during the summer months.
Overall, the combination of these factors results in the Northern Hemisphere experiencing hotter summers than the Southern Hemisphere.
Notice the difference from the hottest temperature at the top of the list – to the coldest temperature at the bottom! The temperature spread on our planet is amazing! These are the hottest and coldest locations in the past 7 days that recorded the associated temperature for at least one hour.
