History[edit]

Riddle was named for William H. Riddle, a native of Springfield, Illinois, who settled in this area in 1851. By 1881, the Southern Pacific Railroad line south of Roseburg had a station here called "Riddlesburg", which was changed to "Riddles" in 1882 and to "Riddle" in 1889. A post office at this location opened under the name of "Riddles" in 1882 and was changed to "Riddle" in 1910.[5]

Climate[edit]

Riddle has a warm-summer Mediterranean climate (Csb) according to the Köppen climate classification system. Summers are cool during the mornings but become hot by afternoon, whilst winters are chilly if not severe, and rainy. During hot spells in the summer, there are 28 afternoons reaching over 90 °F or 32.2 °C and three afternoons over 100 °F or 37.8 °C, although only five mornings have ever stayed at or above 68 °F or 20 °C. The hottest afternoon has been 110 °F (43.3 °C) on August 17, 1977, and the hottest morning 72 °F (22.2 °C) on June 28, 2016. The hottest month on record has been July 2015 with a mean of 75.1 °F (23.9 °C), although the hottest mean maximun is 93.6 °F or 34.2 °C in July 1938 and August 1939.[9]

During winter, most days feature westerly surface and aloft winds, although rainfall is restricted by the coastal mountains. On rare occasions, a block in the Gulf of Alaska will drive cold air from the continent west of the Sierra/Cascade crest, producing much colder than normal weather with either snow or clear skies. The coldest month on record has been January 1937 with a mean of 32.7 °F (0.4 °C) and a maximum of 40.0 °F (4.4 °C). The coldest temperature on record has been −3 °F (−19.4 °C) on January 22, 1962.

The wettest “rain year” was from July 1973 to June 1974 with 50.01 inches (1,270.3 mm) and the driest from July 1976 to June 1977 with 16.20 inches (411.5 mm). The wettest day on record has been November 20, 2012 when 4.43 inches (112.5 mm) fell, and the wettest month December 1996 with 16.72 inches (424.7 mm). Snowfall is rare: the mean is 5.2 inches or 0.13 metres; although the most in one month 42.9 inches (1.09 m) in January 1950 and the most on the ground 13 inches or 0.33 metres on January 13, 1930, eighteen seasons have had zero snowfall and four more only a trace.
