In this article, we list and discuss the 44 Countries With Hot and Wet Equatorial Climate. If you would like to skip our detailed discussion of equatorial climate and its benefits to the economy, you can go directly to the top 8 Countries With Hot and Wet Equatorial Climate.
The equator is an imaginary line on the Earth’s surface at zero-degree latitude, dividing the Earth into two halves, the Northern and Southern hemispheres. According to National Geographic, Earth is widest at its equator and runs around 40,075 kilometers (24,901 miles) distance.
Equatorial climate, also known as the tropical rainforest climate, usually falls upon the countries found within 10 to 15 degrees latitude of the equator. It is a tropical climate sub-type and is characterized by high temperatures of around 30 °C (86 °F), extreme humidity, abundant rainfall, and, most importantly, little to no variation in temperature throughout the year. Regions with Equatorial climates experience hot weather throughout the year as the sun remains almost directly overhead, keeping temperatures high. Also, the Earth's position and the tilt on its axis results in more direct sunlight. These two factors, combined with warm air and the influence of the intertropical convergence zone (ITCZ) all year round also bring about high amounts of rainfall, which accounts for the countries in these regions being hot and wet.
Owing to such a climate, the country and its residents face quite a few challenges, with one of the major challenges being the existence of diseases like Malaria and Dengue Fever. According to the WHO report, there were a total of 2,376,522 dengue observed cases in Brazil, which is one of the 44 countries with a hot and wet Equatorial climate, during the first half of 2023. Other than diseases, there’s a high risk of natural disasters, like hurricanes, as with the increase in proximity to the Equator comes an increase in temperatures, which warms the seawater and results in forming hurricanes.
From an economic perspective, countries near the equator are tropical, and the warm weather and natural beauty act as magnets for tourists. Moreover, these countries are rich in renewable resources like minerals and oil, rare agriculture products, and forest products like timber and wood.
Some equatorial countries are also the leading suppliers of rubber, cocoa, coffee, and palm oil. Therefore, key players and companies dealing in cocoa, palm oil, and other tropical crops may operate in equatorial regions. Some of the key players in the agriculture and rubber industry, like Archer-Daniels-Midland Co (NYSE: ADM), Bunge Global SA (NYSE: BG), and Goodyear Tire & Rubber (NASDAQ: GT), are starting or have started their operations in these countries.
Last year, Archer-Daniels-Midland Co (NYSE: ADM) announced plans to make a series of investments in crush expansion in Brazil to meet the soybean oil demand and sustain the food industry. The company announced investing in three oilseed processing facilities – Campo Grande (Mato Grosso do Sul), Porto Franco (Maranhão), and Uberlândia (Minas Gerais). Moreover, in the same year, Archer-Daniels-Midland Co (NYSE: ADM) acquired Buckminster Química, a glycerin manufacturer for the food and pharmaceutical industries.
On the other hand, Bunge Global SA (NYSE: BG) collaborated last year with Bangkok Produce Merchandising Public Company Limited (BKP) to work on a blockchain technology and develop a solution for the traceability of soybeans as well as deforestation-free products for Brazil-sourced grains. Bunge Global SA (NYSE: BG) says that the partnership will help both companies conduct technical, commercial, and operational feasibility studies and build a sustainable supply chain.
Meanwhile, Goodyear Tire & Rubber (NASDAQ: GT), a global giant in the tire manufacturing industry, has a subsidiary company, Cooper Tire & Rubber Company in Brazil as well. In 2023, Goodyear Tire & Rubber (NASDAQ: GT) had a total of 373,000 import shipments, with 72,700 shipments from Brazil (72,700), according to its OEC company profile.
Overall, while Equatorial countries may have some downsides, they enjoy a significant global standing in industries like rubber, agriculture, and renewable energy.

Our Methodology
For our list of 44 Countries With Hot and Wet Equatorial Climate, we have included all the countries with a hot and wet equatorial climate. These include countries that are:
On or near the equator
Have been typically designated Af by the Köppen climate classification
Have a hot, humid, and wet climate with no dry season.
We’ve picked these countries from South America, Central America, Central Africa, and South East Asia, among others. However, note that not all of these countries fall entirely into the equatorial climate region, but some parts and portions of their lands do. The list is ranked in ascending order based on the average yearly rainfall by country – for countries in which an average rainfall range was involved, we’ve only considered the upper bound.
