Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies. Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter. The Old Farmer's Almanac's extended forecasts can be used to make more informed decisions about future plans that depend on the weather, from vacations and weddings to gardening, hiking, and other outdoor activities. This climate is considered to be Dfa according to the Köppen-Geiger climate classification. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory. A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The figure below shows you a compact characterization of the entire year of hourly average temperatures. Average Weather in Ames Iowa, United States In Ames, the summers are long, warm, humid, and wet; the winters are freezing, dry, and windy; and it is partly cloudy year round. On December 27, the cloudiest day of the year, the sky is overcast or mostly cloudy 56% of the time, and clear, mostly clear, or partly cloudy 44% of the time. The stations contributing to this reconstruction are: Ames Municipal Airport (86%, 4.9 kilometers, south); Boone Municipal Airport (10%, 19 kilometers, west); Marshalltown Municipal Airport (2.0%, 59 kilometers, east); and Iowa Falls Municipal Airport (2.0%, 59 kilometers, northeast). To characterize how pleasant the weather is in Ames throughout the year, we compute two travel scores. Report Station. Daylight saving time (DST) is observed in Ames during 2020, starting in the spring on March 8, lasting 7.8 months, and ending in the fall on November 1. This rainfall is typically spread over 10 days, although this may vary considerably. In 2020, the shortest day is December 21, with 9 hours, 7 minutes of daylight; the longest day is June 20, with 15 hours, 15 minutes of daylight. From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night. The brighter period of the year lasts for 3.6 months, from May 2 to August 22, with an average daily incident shortwave energy per square meter above 6.0 kWh. The growing season in Ames typically lasts for 5.7 months (174 days), from around April 18 to around October 9, rarely starting before March 31 or after May 6, and rarely ending before September 21 or after October 28. : Days with precipitation - Hours sun. The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. While a non-hybrid unit averages $4,600 over a six-month period in fuel and maintenance, the new utility hybrids have averaged $2,000 over the same time frame. Average monthly temperatures in Ames (degrees centigrade and fahrenheit) Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec °C-3.2-0.1: 7.2: 15.6: 22.4: 27.5: 29.7: 28.2 Place. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. (mi.) The average hourly temperature, color coded into bands. Average high temperature Av. The thin dotted line is the corresponding average liquid-equivalent snowfall. Chance of precipitation is 70%. The estimated value at Ames is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Ames and a given station. The rainy period of the year lasts for 10 months, from February 19 to December 20, with a sliding 31-day rainfall of at least 0.5 inches. In Ames, the summers are long, warm, humid, and wet; the winters are freezing, dry, and windy; and it is partly cloudy year round. The drier season lasts 6.3 months, from September 27 to April 4. The rainfall in Ames is significant, with precipitation even during the driest month. Visibility: 10 mi. The least snow falls around July 18, with an average total liquid-equivalent accumulation of 0.0 inches. low temp. : Average precipitation in inch - Days precip. Heat index values as high as 103. New rainfall amounts between a quarter and half of an inch possible. Humidity: 73%. This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
