Travel times

The ideas of what is meant by a particularly favorable travel climate depend on a number of factors. For example, cultural travelers see the climate very differently than people who want to spend a pure beach holiday, for example. The state of health or age can also play an important role.

For sun seekers

For people who like to enjoy a lot of sun and for whom higher temperatures do not cause problems, summer is particularly recommended for a stay or vacation.

For people who prefer a more moderate climate

People who prefer a moderate climate and lower temperatures should better use the following time to stay in Slovenia: spring, autumn.

Winter is usually less suitable for a vacation

Climate table

The following table shows a range of climate data for the country. It should be noted, however, that the climatic conditions in different regions of the country can differ considerably from one another and thus also from the values shown. In addition, such monthly temperature averages say little about the possible current minimum or maximum temperatures. It is not uncommon for average temperatures of around 30 °C to reach maximum values of 40 °C or even more on a number of days. The table therefore only provides a general overview of the climatic conditions in the country.

Historic sites of mercury mining in Almadén and Indrija

Antoni tunnel in Indrija

The town of Indrija with around 6,000 residents is located in the Goriška region in western Slovenia. The city was named Alpine City of the Year 2011.

Mercury has been mined in the Antoni gallery since 1490. A vat maker discovered the mercury. About 150,000 tons of mercury were extracted.

Over the years, new tunnels were dug, so that in the end almost 700 km of tunnels were created.

Idrija was the second largest mercury mine in the world – after Almadén in Spain. Most of the metal was shipped to America at the time because it was needed there for gold mining.

Mercury (lively silver) is a strange metal. It is liquid at room temperature. It has a density of 13.6 g/cm³. Other metals, such as iron, float on the surface of mercury. It’s superconductive.

Mercury is currently still needed by industry, even if attempts are made again and again to replace it with other substances. Nowadays the mine is closed and the “Antoni-Stollen” can be visited as a museum.

Almadén in Spain

Almadén is located in the Spanish province of Ciudad Real and has an area of approx. 240 km². Mercury sulphide (HgS (cinnabar)) has been mined near Almadén for centuries.

Vermilion is a bright red ore, it is not dangerous to humans.

Cinnabar (chemically mercury sulfide) is a solid with a melting point of 386 ° C, so it does not evaporate at normal temperature and is not soluble in water.

It is high in mercury. However, in order to obtain pure mercury, one has to work the ore, which creates toxic mercury fumes that are extremely harmful to health. In the case of minor poisoning, the teeth fall out and there is an abnormally high flow of saliva. Hg is also accumulated in the brain. Mercury-poisoned people usually die of kidney and liver failure and are in severe pain. From 1566 to 1801, many convicts and slaves from North Africa were employed as labor. In 1645 the Spanish state bought the mine. In 1755 a fire broke out in the mine that could not be extinguished for a long time.

The historic mercury mining sites in Almadén and Indrija were inscribed in 2012 on the list of “cross-border” UNESCO World Heritage Sites.
