  Curaçao has a hot, semi-arid climate (Köppen climate classification BSh) with a dry season from January to September and a wet season from October to December. Rainfall is scarce, only 450 millimeters (~17 inches) per year; in particular, the rainy season is drier than it normally is in tropical climates; during the dry season, it almost never rains. Owing to the scarcity of rainfall, the landscape of Curaçao is arid; especially on the north coast of the island. Temperatures are relatively constant, with small differences measured throughout the year. The trade winds cool the island during the day and warm it at night. The coolest month is January with an average temperature of 26.6 °C or 80 °F; the hottest is September with an average temperature of 29.1 °C or 84 °F. The year's average maximum temperature is 31.4 °C or 89 °F. The year's average temperature is 25.7 °C or 78 °F. The seawater around Curaçao averages around 27 °C (81 °F) and is coolest (avg. 25.9 °C) from February to March, and hottest (avg. 28.2 °C) from September to October.
  
  Because Curaçao lies North of the Intertropical Convergence Zone and in an area of low-level divergence where winds flow parallel to the coast, its climate is much drier than expected for the northeastern side of a continent at its latitude. Rainfall is also extremely variable from year to year, being strongly linked to the El Niño Southern Oscillation. As little as 200 millimetres or 8 inches may fall in a strong El Niño year, but as much as 1,150 millimetres or 45 inches is not unknown in powerful La Niña years.
  
  Curaçao lies outside the Main Development Region for tropical cyclones, but is still occasionally affected by them, as with Hurricanes Hazel in 1954, Anna in 1961, Felix in 2007, and Omar in 2008. No hurricane has made landfall in Curaçao since the US National Hurricane Center started tracking hurricanes. Curaçao has, however, been directly affected by pre-hurricane tropical storms several times; the latest being Hurricane Tomas in 2010, Cesar in 1996, Joan in 1988, Cora and Greta in 1978, Edith and Irene in 1971, and Francelia in 1969. Tomas brushed past Curaçao as a tropical storm, dropping as much as 265 mm (10.4 in) of rain on the island, nearly half its annual precipitation in a single day. This made Tomas one of the wettest events in the island's history, as well as one of the most devastating; its flooding killed two people and caused over NAƒ50 million (US$28 million) in damage.
  
  According to the Emissions Database for Global Atmospheric Research, average carbon dioxide emissions per person on the island were 52 tonnes in 2018, the second highest in the world.
