Lying near the equator, Guyana has a tropical climate, and temperatures do not vary much throughout the year. The year has two wet seasons, from December to early February and from late April to mid-August.
Although the temperature never gets dangerously high, the combination of heat and humidity can at times seem oppressive. The entire area is under the influence of the northeast trade winds, and during the midday and afternoon sea breezes bring relief to the coast. Guyana lies south of the path of Caribbean hurricanes and none is known to have hit the country.

Temperatures in Georgetown are quite constant, with an average high of 32°C and an average low of 24°C in the hottest month (July), and an average range of 29°C to 23°C in February, the coolest month. The highest temperature ever recorded in the capital was 37.2°C and the lowest 16.6°C. Humidity averages 70 percent year-round. Locations in the interior, away from the moderating influence of the ocean, experience slightly wider variations in daily temperature, and nighttime readings as low as 12°C have been recorded. Humidity in the interior is also slightly lower, averaging around 60 percent.
Rainfall is heaviest in the northwest and lightest in the southeast and interior. Annual averages on the coast near the Venezuelan border are near 250 centimetres, farther east at New Amsterdam 200 centimetres, and 150 centimetres in southern Guyana's Rupununi Savannah. Areas on the northeast sides of mountains that catch the trade winds average as much as 350 centimeters of precipitation annually. Although rain falls throughout the year, about 50 percent of the annual total arrives in the summer rainy season that extends from May to the end of July along the coast and from April through September farther inland. Coastal areas have a second rainy season from November through January. Rain generally falls in heavy afternoon showers or thunderstorms. Overcast days are rare; most days include four to eight hours of sunshine from morning through early afternoon.
Guyana is a country in Northern South America and part of Caribbean South America, bordering the North Atlantic Ocean, between Suriname and Venezuela. With a land area of approximately 214,970 square kilometres, Guyana is slightly smaller than Laos and slightly larger than Belarus, or about the size of the U.S. state of Idaho. The country is situated between 1 and 9 north latitude and between 56 and 62 west longitude. With a 430-kilometre Atlantic coastline on the northeast, Guyana is bounded by Venezuela on the west, Brazil on the west and south, and Suriname on the east. The land comprises three main geographical zones: the coastal plain, the white sand belt, and the interior highlands.
Guyana, officially named the Co-operative Republic of Guyana, is the only nation state of the Commonwealth of Nations on the mainland of South America. Guyana lies north of the equator, in the tropics, and is located on the Atlantic Ocean. Bordered to the east by Suriname, to the south and southwest by Brazil and to the west by Venezuela, it is the third-smallest country on the mainland of South America. Culturally it is more associated with the Anglo-Caribbean countries than with Latin America and is the only English-speaking country in South America. It is also one of four non-Spanish-speaking territories on the continent, along with the countries of Brazil (Portuguese) and Suriname (Dutch) and the French overseas region of French Guiana (French).
The first Europeans arrived in the area around 1500. Guyana was inhabited by the Arawak and Carib tribes of Amerindians. Although Christopher Columbus sighted Guyana during his third voyage (in 1498), the Dutch were first to establish colonies: Essequibo (1616), Berbice (1627), and Demerara (1752). The British assumed control in the late 18th century, and the Dutch formally ceded the area in 1814. In 1831 the three separate colonies became a single British colony known as British Guiana.
The State House, Guyana's Presidential Residence.Escaped slaves formed their own settlements known as Maroon communities. With the abolition of slavery in 1834 many of the former enslaved people began to settle in urban areas. Indentured labourers from modern day Portugal (1834), Germany (first in 1835), Ireland (1836), Scotland (1837), Malta (1839), China and India (beginning in 1838) were imported to work on the sugar plantations. Today, Indians form the largest ethnic group in Guyana, followed by Africans.
In 1889 Venezuela claimed the land up to the Essequibo. Ten years later an international tribunal ruled the land belonged to British Guiana.
During World War II the United States arranged for its air force to use British airports in South America, including those in British Guiana.
Guyana achieved independence from the United Kingdom in 1966 and became a republic on 23 February 1970, remaining a member of the Commonwealth. The United States State Department and the CIA, along with the British government, played a strong role in influencing who would politically control Guyana during this time.They provided secret financial support and political campaign advice to pro-western Guyanese of African descent, especially Forbes Burnham's People's National Congress to the detriment of the Cheddi Jagan-led People's Progressive Party, mostly supported by Guyanese of Indian descent.
English is the official language of Guyana. In addition, Amerindian languages are spoken by a small minority, while Guyanese Creole (an English-based creole with African and Indian syntax) is widely spoken. Grammar is not standardized.
In addition to English, other languages of Guyana include Guyanese Creole, Akawaio, Wai-Wai, Arawak and Macushi.
Guyana, along with Suriname, French Guiana, and Brazil, is one of the four non-Hispanic nations in South America. Guyana's culture is very similar to that of the English-speaking Caribbean, to the extent that Guyana is included and accepted as a Caribbean nation and is a founding member of the Caricom (Caribbean Community) economic bloc and also the home of the Bloc's Headquarters, the CARICOM Secretariat. Its geographical location, its sparsely populated rain forest regions, and its substantial Amerindian population differentiate it from English-speaking Caribbean countries. Its blend of Indo-Guyanese (East Indian) and Afro-Guyanese (African) cultures gives it similarities to Trinidad and distinguishes it from other parts of the Americas. Guyana shares similar interests with the islands in the West Indies, such as food, festive events, music, sports, etc. Guyana plays international cricket as a part of the West Indies cricket team, and the Guyana team plays first class cricket against other nations of the Caribbean. In addition to its CARICOM membership, Guyana is a member of CONCACAF, the international football federation for North and Central America and the Caribbean. Another aspect of Guyanese culture is its rich folklore about Jumbees.
