<P> At the equinoxes, the Earth's axis is perpendicular to the sun rather than tilted toward or away, meaning that day and night are both about 12 hours long across the whole of the Earth . </P> <P> The Equator lies mostly on the three largest oceans: the Atlantic Ocean, the Indian Ocean, and the Pacific Ocean . Near the Equator there is little temperature change throughout the year, though there may be dramatic differences in rainfall and humidity . The terms summer, autumn, winter and spring do not generally apply . Lowlands around the Equator generally have a tropical rainforest climate, also known as an equatorial climate, though cold currents cause some regions to have tropical monsoon climates with a dry season in the middle of the year, and the Somali Current generated by the Asian monsoon due to continental heating via the high Tibetan Plateau causes Greater Somalia to have an arid climate despite its equatorial location . </P> <P> Average annual temperatures in equatorial lowlands are around 31 ° C (88 ° F) during the afternoon and 23 ° C (73 ° F) around sunrise . Rainfall is away from cold current upwelling zones very high, from 2,500 to 3,500 mm (98 to 138 in) per year . There are about 200 rainy days per year and average annual sunshine hours are around 2,000 . Despite high year - round sea level temperatures, some higher altitudes such as the Andes and Mount Kilimanjaro have glaciers . The highest point on the Equator is at the elevation of 4,690 metres (15,387 ft), at 0 ° 0 ′ 0" N 77 ° 59 ′ 31" W ﻿ / ﻿ 0.00000 ° N 77.99194 ° W ﻿ / 0.00000; - 77.99194 ﻿ (highest point on the Equator), found on the southern slopes of Volcán Cayambe (summit 5,790 metres (18,996 ft)) in Ecuador . This is slightly above the snow line and is the only place on the Equator where snow lies on the ground . At the Equator the snow line is around 1,000 metres (3,280 ft) lower than on Mount Everest and as much as 2,000 metres (6,560 ft) lower than the highest snow line in the world, near the Tropic of Capricorn on Llullaillaco . </P> <Table> <Tr> <Th_colspan="14"> (hide) Climate data for Macapá, Brazil in South America </Th> </Tr> <Tr> <Th> Month </Th> <Th> Jan </Th> <Th> Feb </Th> <Th> Mar </Th> <Th> Apr </Th> <Th> May </Th> <Th> Jun </Th> <Th> Jul </Th> <Th> Aug </Th> <Th> Sep </Th> <Th> Oct </Th> <Th> Nov </Th> <Th> Dec </Th> <Th> Year </Th> </Tr> <Tr> <Th> Average high ° C (° F) </Th> <Td> 29.7 (85.5) </Td> <Td> 29.2 (84.6) </Td> <Td> 29.3 (84.7) </Td> <Td> 29.5 (85.1) </Td> <Td> 30.0 (86) </Td> <Td> 30.3 (86.5) </Td> <Td> 30.6 (87.1) </Td> <Td> 31.5 (88.7) </Td> <Td> 32.1 (89.8) </Td> <Td> 32.6 (90.7) </Td> <Td> 32.3 (90.1) </Td> <Td> 31.4 (88.5) </Td> <Td> 30.71 (87.28) </Td> </Tr> <Tr> <Th> Daily mean ° C (° F) </Th> <Td> 26.4 (79.5) </Td> <Td> 26.2 (79.2) </Td> <Td> 26.3 (79.3) </Td> <Td> 26.5 (79.7) </Td> <Td> 26.8 (80.2) </Td> <Td> 26.8 (80.2) </Td> <Td> 26.8 (80.2) </Td> <Td> 27.4 (81.3) </Td> <Td> 27.8 (82) </Td> <Td> 28.1 (82.6) </Td> <Td> 27.9 (82.2) </Td> <Td> 27.4 (81.3) </Td> <Td> 27.03 (80.65) </Td> </Tr> <Tr> <Th> Average low ° C (° F) </Th> <Td> 23.0 (73.4) </Td> <Td> 23.1 (73.6) </Td> <Td> 23.2 (73.8) </Td> <Td> 23.5 (74.3) </Td> <Td> 23.5 (74.3) </Td> <Td> 23.2 (73.8) </Td> <Td> 22.9 (73.2) </Td> <Td> 23.3 (73.9) </Td> <Td> 23.4 (74.1) </Td> <Td> 23.5 (74.3) </Td> <Td> 23.5 (74.3) </Td> <Td> 23.4 (74.1) </Td> <Td> 23.29 (73.92) </Td> </Tr> <Tr> <Th> Average rainfall mm (inches) </Th> <Td> 299.6 (11.795) </Td> <Td> 347.0 (13.661) </Td> <Td> 407.2 (16.031) </Td> <Td> 384.3 (15.13) </Td> <Td> 351.5 (13.839) </Td> <Td> 220.1 (8.665) </Td> <Td> 184.8 (7.276) </Td> <Td> 98.00 (3.8583) </Td> <Td> 42.60 (1.6772) </Td> <Td> 35.50 (1.3976) </Td> <Td> 58.40 (2.2992) </Td> <Td> 142.5 (5.61) </Td> <Td> 2,571.5 (101.2393) </Td> </Tr> <Tr> <Th> Average rainy days (≥ 0.1 mm) </Th> <Td> 23 </Td> <Td> 22 </Td> <Td> 24 </Td> <Td> 24 </Td> <Td> 25 </Td> <Td> 22 </Td> <Td> 19 </Td> <Td> 13 </Td> <Td> 6 </Td> <Td> 5 </Td> <Td> 6 </Td> <Td> 14 </Td> <Td> 203 </Td> </Tr> <Tr> <Th> Mean monthly sunshine hours </Th> <Td> 148.8 </Td> <Td> 113.1 </Td> <Td> 108.5 </Td> <Td> 114.0 </Td> <Td> 151.9 </Td> <Td> 189.0 </Td> <Td> 226.3 </Td> <Td> 272.8 </Td> <Td> 273.0 </Td> <Td> 282.1 </Td> <Td> 252.0 </Td> <Td> 204.6 </Td> <Td> 2,336.1 </Td> </Tr> <Tr> <Td_colspan="14"> Source: World Meteorological Organization (UN), Hong Kong Observatory </Td> </Tr> </Table>
