<P> The hottest months are July and August, with average highs of around 82 ° F (28 ° C), with an average of 15 days per year above 90 ° F (32.2 ° C). The coolest month is December, with the average daytime high in the mid-40s ° F (7--8 ° C), and nights averaging just above freezing . There are 54 nights per year with a low below freezing, and about three days with highs not exceeding freezing . The record high low was 73 ° F (23 ° C) in 2006 . </P> <P> Eugene's average annual temperature is 52.1 ° F (11.2 ° C), and annual precipitation at 50.9 inches (1,290 mm). Eugene is more wet and slightly cooler on average than Portland . Despite being located about 100 miles (160 km) south and having only a slightly higher elevation, Eugene has a more continental climate, less subject to the maritime air that blows inland from the Pacific Ocean via the Columbia River . Eugene's average August low is 50.8 ° F (10.4 ° C), while Portland's average August low is 56.5 ° F (13.6 ° C). Average winter temperatures (and summer high temperatures) are similar for the two cities . This disparity may be additionally caused by Portland's urban heat island, where the combination of black pavement and urban energy use raises nighttime temperatures . </P> <P> Extreme temperatures range from − 12 ° F (− 24 ° C), recorded on December 8, 1972, to 108 ° F (42 ° C) on August 9, 1981 . </P> <Table> <Tr> <Th_colspan="14"> (hide) Climate data for Eugene, Oregon (Eugene Airport), 1981--2010 normals </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 ° F (° C) </Th> <Td> 69 (21) </Td> <Td> 78 (26) </Td> <Td> 80 (27) </Td> <Td> 89 (32) </Td> <Td> 95 (35) </Td> <Td> 102 (39) </Td> <Td> 106 (41) </Td> <Td> 108 (42) </Td> <Td> 103 (39) </Td> <Td> 94 (34) </Td> <Td> 76 (24) </Td> <Td> 68 (20) </Td> <Td> 108 (42) </Td> </Tr> <Tr> <Th> Average high ° F (° C) </Th> <Td> 47.2 (8.4) </Td> <Td> 51.1 (10.6) </Td> <Td> 56.2 (13.4) </Td> <Td> 60.8 (16) </Td> <Td> 67.0 (19.4) </Td> <Td> 73.2 (22.9) </Td> <Td> 82.2 (27.9) </Td> <Td> 82.8 (28.2) </Td> <Td> 76.9 (24.9) </Td> <Td> 64.2 (17.9) </Td> <Td> 52.2 (11.2) </Td> <Td> 45.6 (7.6) </Td> <Td> 63.3 (17.4) </Td> </Tr> <Tr> <Th> Average low ° F (° C) </Th> <Td> 34.5 (1.4) </Td> <Td> 35.1 (1.7) </Td> <Td> 37.4 (3) </Td> <Td> 39.8 (4.3) </Td> <Td> 43.8 (6.6) </Td> <Td> 47.9 (8.8) </Td> <Td> 51.7 (10.9) </Td> <Td> 51.4 (10.8) </Td> <Td> 47.3 (8.5) </Td> <Td> 41.5 (5.3) </Td> <Td> 37.9 (3.3) </Td> <Td> 34.1 (1.2) </Td> <Td> 41.9 (5.5) </Td> </Tr> <Tr> <Th> Record low ° F (° C) </Th> <Td> − 4 (− 20) </Td> <Td> − 3 (− 19) </Td> <Td> 18 (− 8) </Td> <Td> 25 (− 4) </Td> <Td> 28 (− 2) </Td> <Td> 32 (0) </Td> <Td> 39 (4) </Td> <Td> 35 (2) </Td> <Td> 30 (− 1) </Td> <Td> 17 (− 8) </Td> <Td> 12 (− 11) </Td> <Td> − 12 (− 24) </Td> <Td> − 12 (− 24) </Td> </Tr> <Tr> <Th> Average precipitation inches (mm) </Th> <Td> 6.89 (175) </Td> <Td> 5.43 (137.9) </Td> <Td> 4.99 (126.7) </Td> <Td> 3.33 (84.6) </Td> <Td> 2.73 (69.3) </Td> <Td> 1.50 (38.1) </Td> <Td> 0.55 (14) </Td> <Td> 0.61 (15.5) </Td> <Td> 1.29 (32.8) </Td> <Td> 3.25 (82.6) </Td> <Td> 7.72 (196.1) </Td> <Td> 7.83 (198.9) </Td> <Td> 46.12 (1,171.4) </Td> </Tr> <Tr> <Th> Average snowfall inches (cm) </Th> <Td> 0.5 (1.3) </Td> <Td> 1.4 (3.6) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0 (0) </Td> <Td> 0.1 (0.3) </Td> <Td> 0.8 (2) </Td> <Td> 2.8 (7.1) </Td> </Tr> <Tr> <Th> Average precipitation days (≥ 0.01 in) </Th> <Td> 17.8 </Td> <Td> 14.9 </Td> <Td> 17.7 </Td> <Td> 14.5 </Td> <Td> 11.7 </Td> <Td> 7.9 </Td> <Td> 3.1 </Td> <Td> 3.2 </Td> <Td> 5.4 </Td> <Td> 11.4 </Td> <Td> 17.9 </Td> <Td> 17.9 </Td> <Td> 143.4 </Td> </Tr> <Tr> <Th> Average snowy days (≥ 0.1 in) </Th> <Td> 0.4 </Td> <Td> 0.7 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0.1 </Td> <Td> 0.5 </Td> <Td> 1.7 </Td> </Tr> <Tr> <Td_colspan="14"> Source: NOAA Weather.com (extremes) </Td> </Tr> </Table>
