<P> North Carolina's climate varies from the Atlantic coast in the east to the Appalachian Mountain range in the west . The mountains often act as a "shield", blocking low temperatures and storms from the Midwest from entering the Piedmont of North Carolina . Most of the state has a humid subtropical climate (Köppen climate classification Cfa), except in the higher elevations of the Appalachians which have a subtropical highland climate (Köppen Cfb). For most areas in the state, the temperatures in July during the daytime are approximately 90 ° F (32 ° C). In January the average temperatures range near 50 ° F (10 ° C). (However, a polar vortex or "cold blast" can significantly bring down average temperatures, seen in the winters of 2014 and 2015 .) </P> <Table> Average Monthly Temperature <Tr> <Th> City </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> </Tr> <Tr> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> </Tr> <Tr> <Th> Asheville </Th> <Td> 46 / 26 </Td> <Td> 50 / 28 </Td> <Td> 58 / 35 </Td> <Td> 66 / 42 </Td> <Td> 74 / 51 </Td> <Td> 80 / 58 </Td> <Td> 83 / 63 </Td> <Td> 82 / 62 </Td> <Td> 76 / 55 </Td> <Td> 67 / 43 </Td> <Td> 57 / 35 </Td> <Td> 49 / 29 </Td> </Tr> <Tr> <Th> Cape Hatteras </Th> <Td> 54 / 39 </Td> <Td> 55 / 39 </Td> <Td> 60 / 44 </Td> <Td> 68 / 52 </Td> <Td> 75 / 60 </Td> <Td> 82 / 68 </Td> <Td> 85 / 73 </Td> <Td> 85 / 72 </Td> <Td> 81 / 68 </Td> <Td> 73 / 59 </Td> <Td> 65 / 50 </Td> <Td> 57 / 43 </Td> </Tr> <Tr> <Th> Charlotte </Th> <Td> 51 / 32 </Td> <Td> 56 / 34 </Td> <Td> 64 / 42 </Td> <Td> 73 / 49 </Td> <Td> 80 / 58 </Td> <Td> 87 / 66 </Td> <Td> 90 / 71 </Td> <Td> 88 / 69 </Td> <Td> 82 / 63 </Td> <Td> 73 / 51 </Td> <Td> 63 / 42 </Td> <Td> 54 / 35 </Td> </Tr> <Tr> <Th> Greensboro </Th> <Td> 47 / 28 </Td> <Td> 52 / 31 </Td> <Td> 60 / 38 </Td> <Td> 70 / 46 </Td> <Td> 77 / 55 </Td> <Td> 84 / 64 </Td> <Td> 88 / 68 </Td> <Td> 86 / 67 </Td> <Td> 79 / 60 </Td> <Td> 70 / 48 </Td> <Td> 60 / 39 </Td> <Td> 51 / 31 </Td> </Tr> <Tr> <Th> Raleigh </Th> <Td> 50 / 30 </Td> <Td> 54 / 32 </Td> <Td> 62 / 39 </Td> <Td> 72 / 46 </Td> <Td> 79 / 55 </Td> <Td> 86 / 64 </Td> <Td> 89 / 68 </Td> <Td> 87 / 67 </Td> <Td> 81 / 61 </Td> <Td> 72 / 48 </Td> <Td> 62 / 40 </Td> <Td> 53 / 33 </Td> </Tr> <Tr> <Th> Wilmington </Th> <Td> 56 / 36 </Td> <Td> 60 / 38 </Td> <Td> 66 / 44 </Td> <Td> 74 / 51 </Td> <Td> 81 / 60 </Td> <Td> 86 / 68 </Td> <Td> 90 / 72 </Td> <Td> 88 / 71 </Td> <Td> 84 / 66 </Td> <Td> 76 / 54 </Td> <Td> 68 / 45 </Td> <Td> 60 / 38 </Td> </Tr> </Table> <Tr> <Th> City </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> </Tr>
