Denver has several additional professional teams. In 2006 Denver established a Major League Lacrosse team, the Denver Outlaws. They play in Sports Authority Field at Mile High. In 2006, the Denver Outlaws won the Western Conference Championship, and then went on to become 2014 MLL Champions, eight years later. The Colorado Mammoth of the National Lacrosse League play at the Pepsi Center.
July is the warmest month, with a daily average temperature of 74.2 °F (23.4 °C). Summers range from mild to hot with occasional, sometimes severe, afternoon thunderstorms and high temperatures reaching 90 °F (32 °C) on 38 days annually, and occasionally 100 °F (38 °C). December, the coldest month of the year, has a daily average temperature of 29.9 °F (−1.2 °C). Winters consist of periods of snow and very low temperatures alternating with periods of milder weather due to the warming effect of Chinook winds. In winter, daytime highs can exceed 60 °F (16 °C) but also often fail to reach 32 °F (0 °C) during periods of cold weather and can even fail to rise above 0 °F (−18 °C) on occasion. On the coldest nights of the year, lows can easily fall to −10 °F (−23 °C) or below. Snowfall is common throughout the late fall, winter and early spring, averaging 53.5 inches (136 cm) for 1981–2010. The average window for measurable (≥0.1 in or 0.25 cm) snow is October 17 through April 27; however, measurable snowfall has fallen in Denver as early as September 4 and as late as June 3. Extremes in temperature range from −29 °F (−34 °C) on January 9, 1875, up to 105 °F (41 °C) as recently as June 29, 2018. Due to the city's high elevation and aridity, diurnal temperature variation is large throughout the year.
Denver has many nationally recognized museums, including a new wing for the Denver Art Museum by world-renowned architect Daniel Libeskind, the second largest Performing Arts Center in the nation after Lincoln Center in New York City and bustling neighborhoods such as LoDo, filled with art galleries, restaurants, bars and clubs. That is part of the reason why Denver was, in 2006, recognized for the third year in a row as the best city for singles. Denver's neighborhoods also continue their influx of diverse people and businesses while the city's cultural institutions grow and prosper. The city acquired the estate of abstract expressionist painter Clyfford Still in 2004 and built a museum to exhibit his works near the Denver Art Museum. The Denver Museum of Nature and Science holds an aquamarine specimen valued at over $1 million, as well as specimens of the state mineral, rhodochrosite. Every September the Denver Mart, at 451 E. 58th Avenue, hosts a gem and mineral show. The state history museum, History Colorado Center, opened in April 2012. It features hands-on and interactive exhibits, artifacts and programs about Colorado history. It was named in 2013 by True West Magazine as one of the top-ten "must see" history museums in the country. History Colorado's Byers-Evans House Museum and the Molly Brown House are nearby.
