One thing we do know though, Mt Cayambe, near Quito, Ecuador is the most interesting cold place in South America, it has a daytime average of 2 degrees celsius and an overnight average of -10 C and lies almost directly on the equator.

South America: Lowest Temperature

As winter settles over the Southern Hemisphere, South America has been lashed with snow, heavy rain and intense cold since the final week of June 2004. Unusually cold temperatures, down to -7 Celsius (19.4 Fahrenheit), chilled southern Brazil. …

Snowfall occasionally occurs in the surrounding areas of the city but rarely within Buenos Aires proper; since the start of meteorological observations in 1906 at the central observatory, snowfall has only been observed thrice: June 1918, July 1928, and July 2007.

November

Buenos Aires has a mild and warm climate throughout the year. The winter months are June to August, the summer months are December to February, the spring months are September to November, and the autumn months are March, April and May.

The tap water in Buenos Aires is safe to drink but is pretty awful. So many people use bottled water which is more and more expensive or a filter. “You even have to pay for water now.” Everywhere in Europe you go to any shop and they will give you bottled water free of charge.

The water from the tap in Guyana comes out brown, due to the chemicals in the water, which can be interesting if you’re not expecting it! The water isn’t polluted, but the tap water is generally not safe to drink.

Large parts of South America are in the grip of a serious drought. Signs of the drought began to appear in satellite gravimetry observations of southeastern Brazil in mid-2018, and had spread into parts of Paraguay, Bolivia, and northern Argentina by 2020.

In October 2020 South America experienced the second most intense drought in almost 2 decades, according to Matthew Rodell, a hydrologist at the NASA Goddard Space Flight Center.

According to Drought Crisis: The Global Thirst for Water in the Era of Climate Change, the impact of extreme droughts is growing worldwide, including in Europe, putting increasing pressure on energy supplies, food production, wetlands and cities and impacting 55 million every year on average.

The expansion of deforestation activities into the Amazon basin has been linked to the reduction of rainfall in the south of Brazil. Even if the Amazon’s evaporation was enough to generate flying rivers, urban heat islands coupled with a heat wave prevented the arrival of humid air masses that generate rain.

Pollution of air, land and water is a major problem. Air pollution is second only to Los Angeles.

Water supply and sanitation in Brazil

Abstract: Drought-related disasters are among the natural disasters that are able to cause large economic and social losses. In recent years, droughts have affected different regions of Brazil, impacting water, food, and energy security.

Agência FAPESP – Brazil’s internal consumption and exports of soybean, beef and other primary products from the Amazon are responsible for more than half of the deforestation rate and greenhouse gas emissions of the biome. The Amazon contributed more than 50% of the country’s greenhouse gas emissions.

Low precipitation has an immediate impact on agriculture. Deforesting the Amazon to establish cattle ranches, plantations and logging reduces precipitation in Brazil and other Latin American countries. With deforestation increasing, agribusiness and power generation may collapse in Brazil.
