Where can you go on any day of the year?

Are there areas in the world where the weather is perfect all year round? Let's see where you can go regardless of the season.

In order to check if such areas in the world exist at all, I analyzed the average weekly values of UTCI index presented on the home page for each place in the world. From the database I selected all the areas where the index for the coldest week was above 9 degrees Celsius and the warmest week was below 26 degrees Celsius. This interval is defined as no heat load. It should be remembered that the indicator, although expressed in degrees Celsius, does not show only the air temperature, but also takes into account effects such as wind speed, air humidity and solar radiation intensity.

So where are the areas, where regardless of the season will not be too hot or too cold?

In Europe, year-round favourable conditions are only found on parts of the Portuguese coast (e.g. around Portimão or near Lisbon and Spain (e.g. around Malaga)) and around Gibraltar.  In this area, however, the likelihood of precipitation increases during the winter months. The Canary Islands are also an ideal example of such places.

Fortunately, there are more such areas - there are three stretched belts, which are characterized by the presence of a mild climate throughout the year.

The first of these is a belt stretching south through central Mexico, then along the Andes to the latitude of Santiago de Chile. Once precipitation is taken into account, this area narrows down to the regions of Chile: Región de Antofagasta and Región de Atacama. It is important to remember that the UTCI analysis is only for the sunny day period; nighttime temperatures can drop sharply, especially in dry climates.

The second area is a belt stretching south through eastern Africa - from Eritrea to South Africa. The latitude (near the equator) and the varied terrain make it possible to expect heavy precipitation. In this analysis, the frequency of precipitation is taken into account throughout the year, to see more detailed data and seasonality of phenomena, please visit the main page.

The third belt, this time extending latitudinally, is the foothills of the Himalayas. The narrow belt begins in northern India, runs through Nepal and again through parts of India and Myanmar stretching into Yunnan Province. Due to the summer monsoons, however, this is not an ideal area to visit year-round (for this reason the map below does not show rainfall). Smaller dense areas also include the eastern strip running down the middle of the island of Papua and the coast of Australia (the east coast strip, but also the west and southwest coast, including the area around Perth).

This is the first in a series of aricles on global climate. More will be coming soon.
