Guide to Extreme Temperatures by Geographic Zones

Understanding what constitutes extreme heat is crucial for safety and preparedness. Different regions have varying thresholds for what is considered high temperatures, influenced by their typical climate conditions. Here is a guide detailing the temperatures considered extreme across various countries:

Canada:

In Canada, particularly in the northern and coastal regions, temperatures above 30°C (86°F) are considered high. In the more temperate southern regions, such as Ontario and British Columbia, temperatures above 35°C (95°F) are extreme.

United States:

In the US, temperatures above 35°C (95°F) are generally considered high, especially in the northern states. In the southern states, such as Texas, Arizona, and Florida, extreme heat is defined as temperatures exceeding 40°C (104°F).

Mexico:

In Mexico, temperatures above 35°C (95°F) are common in many regions. In areas like the Sonoran Desert, temperatures often exceed 40°C (104°F), marking extreme heat conditions.

Brazil:

In Brazil, temperatures above 35°C (95°F) are considered high, particularly in the interior regions. Coastal areas typically experience slightly lower temperatures due to oceanic influences.

Chile:

In Chile, extreme heat is defined as temperatures above 35°C (95°F), particularly in the central valleys and northern desert regions. The coastal areas generally remain cooler.

Peru:

In Peru, temperatures above 35°C (95°F) are considered high, especially in the coastal and jungle regions. The Andean highlands experience significantly lower temperatures.

Argentina:

In Argentina, temperatures above 35°C (95°F) are considered high, particularly in the northern and central regions. The southern regions, including Patagonia, experience much cooler temperatures.

South Africa:

In South Africa, temperatures above 35°C (95°F) are considered high. The northern and interior regions are more prone to extreme heat compared to the coastal areas.

Egypt:

In Egypt, extreme heat is defined as temperatures exceeding 40°C (104°F), which are common in the desert regions and during the summer months across the country.

Saudi Arabia:

In Saudi Arabia, temperatures above 40°C (104°F) are typical during the summer months, with extreme heat often exceeding 45°C (113°F) in desert areas.

Spain:

In Spain, temperatures above 35°C (95°F) are considered high, particularly in the interior and southern regions. Coastal areas tend to have more moderate temperatures.

United Kingdom:

In the UK, temperatures above 30°C (86°F) are considered high and relatively uncommon. Such temperatures typically occur during heatwaves in the summer months.

France:

In France, temperatures above 35°C (95°F) are considered high, particularly in the southern regions. The northern areas experience lower extreme temperatures.

Germany:

In Germany, temperatures above 30°C (86°F) are considered high. Heatwaves occasionally push temperatures above 35°C (95°F), particularly in the summer.

Italy:

In Italy, temperatures above 35°C (95°F) are common in the summer, especially in the central and southern regions. Northern areas generally experience slightly cooler temperatures.

Sweden:

In Sweden, temperatures above 30°C (86°F) are considered high. Such temperatures are relatively rare and typically occur during short heatwaves in the summer.

Russia:

In Russia, temperatures above 30°C (86°F) are considered high, particularly in the northern and central regions. Southern regions, like the Black Sea coast, can experience temperatures above 35°C (95°F).

India:

In India, temperatures above 40°C (104°F) are common during the summer months, particularly in the northern and central regions. Coastal areas are slightly cooler but still experience high temperatures.

Japan:

In Japan, temperatures above 35°C (95°F) are considered high and are common during the summer months. The humidity levels also make the heat feel more intense.

Australia:

In Australia, temperatures above 35°C (95°F) are common in many regions during the summer. In the interior deserts, temperatures can exceed 40°C (104°F), marking extreme heat conditions.

Understanding these regional temperature thresholds helps in preparing for and managing heatwaves effectively. Adapting to these conditions requires appropriate hydration, clothing, and behavioral changes to stay safe and healthy.
