<P> Guantánamo Bay (Spanish: Bahía de Guantánamo) is a bay located in Guantánamo Province at the southeastern end of Cuba . It is the largest harbor on the south side of the island and it is surrounded by steep hills which create an enclave that is cut off from its immediate hinterland . </P> <P> The United States assumed territorial control over the southern portion of Guantánamo Bay under the 1903 Lease agreement . The United States exercises complete jurisdiction and control over this territory, while recognizing that Cuba retains ultimate sovereignty . The current government of Cuba regards the U.S. presence in Guantánamo Bay as illegal and insists the Cuban--American Treaty was obtained by threat of force and is in violation of international law . Some legal scholars judge that the lease may be voidable . It is the home of the Guantanamo Bay Naval Base and the Guantanamo Bay detention camp located within the base, which are both governed by the United States . Since the 1959 revolution, Cuba has only cashed a single lease payment from the United States government . </P> <Table> <Tr> <Th_colspan="14"> (hide) Climate data for Guantánamo Bay </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> Record high ° C (° F) </Th> <Td> 35 (95) </Td> <Td> 35 (95) </Td> <Td> 33 (91) </Td> <Td> 35 (95) </Td> <Td> 37 (99) </Td> <Td> 37 (99) </Td> <Td> 39 (102) </Td> <Td> 37 (99) </Td> <Td> 37 (99) </Td> <Td> 38 (100) </Td> <Td> 39 (102) </Td> <Td> 35 (95) </Td> <Td> 39 (102) </Td> </Tr> <Tr> <Th> Average high ° C (° F) </Th> <Td> 29 (85) </Td> <Td> 29 (85) </Td> <Td> 30 (86) </Td> <Td> 31 (87) </Td> <Td> 31 (88) </Td> <Td> 32 (90) </Td> <Td> 33 (91) </Td> <Td> 33 (92) </Td> <Td> 33 (91) </Td> <Td> 32 (89) </Td> <Td> 31 (88) </Td> <Td> 30 (86) </Td> <Td> 31 (88) </Td> </Tr> <Tr> <Th> Average low ° C (° F) </Th> <Td> 20 (68) </Td> <Td> 20 (68) </Td> <Td> 21 (70) </Td> <Td> 22 (72) </Td> <Td> 23 (74) </Td> <Td> 24 (76) </Td> <Td> 24 (76) </Td> <Td> 24 (76) </Td> <Td> 24 (76) </Td> <Td> 24 (75) </Td> <Td> 23 (73) </Td> <Td> 21 (70) </Td> <Td> 22.5 (72.8) </Td> </Tr> <Tr> <Th> Record low ° C (° F) </Th> <Td> 13 (55) </Td> <Td> 13 (55) </Td> <Td> 16 (61) </Td> <Td> 17 (63) </Td> <Td> 18 (64) </Td> <Td> 20 (68) </Td> <Td> 21 (70) </Td> <Td> 20 (68) </Td> <Td> 19 (66) </Td> <Td> 18 (64) </Td> <Td> 16 (61) </Td> <Td> 13 (55) </Td> <Td> 13 (55) </Td> </Tr> <Tr> <Th> Average precipitation cm (inches) </Th> <Td> (1) </Td> <Td> 2.3 (0.9) </Td> <Td> (1.2) </Td> <Td> 3.3 (1.3) </Td> <Td> 9.1 (3.6) </Td> <Td> 5.3 (2.1) </Td> <Td> 2.8 (1.1) </Td> <Td> 4.8 (1.9) </Td> <Td> 8 (3) </Td> <Td> 13 (5.1) </Td> <Td> 4.6 (1.8) </Td> <Td> 2.8 (1.1) </Td> <Td> 61.5 (24.2) </Td> </Tr> <Tr> <Td_colspan="14"> Source: Weatherbase </Td> </Tr> </Table>
