Spring and autumn, from March to May and from early October to late November, are generally warm to hot seasons, with infrequent rains (but when it rains, the rains can be abundant). Indeed, New Orleans was catastrophically hit by Hurricane Katrina in late August 2005, when the levees were broken by the waters that flooded the city. Due to its position at sea level (and in some areas even below) and surrounded by water, the city is particularly at risk. Hurricane season runs from June to November, although the period in which they are most likely is from August to October. The sun often shines, but the sky is not always clear, as cloud coverings can form, which can give rise to thunderstorms.īetween late summer and early autumn, New Orleans can be affected by hurricanes or tropical storms. The record is 39 ☌ (102 ☏), recorded in August 1980. On the hottest days of the year, the temperature usually reaches 37/38 ☌ (99/100 ☏). The combination of humidity and temperature can produce a perceived temperature of 40 ☌ (104 ☏) and above. Due to high humidity the heat is sweltering, even though the breeze blows from the sea. The summer, from June to September, is hot and muggy. Sometimes the dangerous phenomenon of freezing rain can also occur. The last time a light white blanket formed was in December 2008. On Christmas Eve 2004, 2 centimeters (0.7 in) of snow fell. On December 22, 1989, 2 to 5 cm (1-2 in) fell depending on the area of the city. On the New Year's Eve in 1963, 11 cm (4.5 inches) of snow fell. Snow in New Orleans is very rare, however, from time to time there may be a snowfall with a few centimeters of accumulation. In January 1963 and January 1985, the temperature dropped to -10 ☌ (14 ☏), with a maximum of -1 ☌ (30 ☏). The record is -11.5 ☌ (11 ☏), recorded in December 1989, with a maximum of 0 ☌. However, there may also be short cold spells, in which the temperature drops below freezing, usually down to -5/-6 ☌ (21/23 ☏), while during the day it remains about 5/6 ☌ (41/43 ☏). There may be warm periods even in the middle of winter, when the temperature can reach or exceed 25 ☌ (77 ☏).
