Question: When does the monsoon season end in the state where the Raton Municipal Airport is?

full_context: Document 1: North American Monsoon: The North American monsoon, variously known as the Southwest monsoon, the Mexican monsoon, the New Mexican monsoon, or the Arizona monsoon, is a pattern of pronounced increase in thunderstorms and rainfall over large areas of the southwestern United States and northwestern Mexico, typically occurring between July and mid September. During the monsoon, thunderstorms are fueled by daytime heating and build up during the late afternoon - early evening. Typically, these storms dissipate by late night, and the next day starts out fair, with the cycle repeating daily. The monsoon typically loses its energy by mid-September when drier and cooler conditions are reestablished over the region. Geographically, the North American monsoon precipitation region is centered over the Sierra Madre Occidental in the Mexican states of Sinaloa, Durango, Sonora and Chihuahua.
Document 2: Tunica Municipal Airport: Tunica Municipal Airport is a public use airport located one nautical mile (2 km) east of the central business district of Tunica, in Tunica County, Mississippi, United States. It is owned by the Tunica County Airport Commission. Also known as Tunica Airport, it should not be confused with the 10 acre privately owned, public use Tunica Airport located south of the center of town, which has been recently changed to Ralph M Sharpe Airport.
Document 3: Ticonderoga Municipal Airport: Ticonderoga Municipal Airport is a public use airport located two nautical miles (4 km) northeast of Ticonderoga, a hamlet in the Town of Ticonderoga, Essex County, New York, United States. The airport is owned by the Town of Ticonderoga. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a "general aviation" facility.
Document 4: Monsoon of South Asia: The monsoon of South Asia is among several geographically distributed global monsoons. It affects the Indian subcontinent, where it is one of the oldest and most anticipated weather phenomena and an economically important pattern every year from June through September. Yet it is only partly understood and notoriously difficult to predict. Several theories have been proposed to explain the origin, process, strength, variability, distribution, and general vagaries of the monsoon, but understanding and predictability are still evolving.
Document 5: Climate of Pakistan: Western Disturbances mostly occur during the winter months and cause light to moderate showers in southern parts of the country while moderate to heavy showers with heavy snowfall in the northern parts of the country. These westerly waves are robbed of most of the moisture by the time they reach Pakistan. Fog occurs during the winter season and remains for weeks in upper Sindh, central Khyber Pakhtunkhwa and Punjab. Southwest Monsoon occurs in summer from the month of June till September in almost whole Pakistan excluding western Balochistan, FATA, Chitral and Gilgit -- Baltistan. Monsoon rains bring much awaited relief from the scorching summer heat. These monsoon rains are quite heavy by nature and can cause significant flooding, even severe flooding if they interact with westerly waves in the upper parts of the country. Tropical Storms usually form during the summer months from late April till June and then from late September till November. They affect the coastal localities of the country. Dust storms occur during summer months with peak in May and June, They are locally known as Andhi. These dust storms are quite violent. Dust storms during the early summer indicate the arrival of the monsoons while dust storms in the autumn indicate the arrival of winter. Heat waves occur during May and June, especially in southern Punjab, central Balochistan and interior Sindh. Thunderstorms most commonly occur in northern Punjab, Khyber Pakhtunkhwa and Azad Kashmir. Continental air prevails during the period when there is no precipitation in the country.
Document 6: Dodge City Regional Airport: Dodge City Regional Airport is three miles east of Dodge City, in Ford County, Kansas. It is used for general aviation and was at one point subsidized by the Essential Air Service program.
Document 7: Punjab, Pakistan: The onset of the southwest monsoon is anticipated to reach Punjab by May, but since the early 1970s the weather pattern has been irregular. The spring monsoon has either skipped over the area or has caused it to rain so hard that floods have resulted. June and July are oppressively hot. Although official estimates rarely place the temperature above 46 °C, newspaper sources claim that it reaches 51 °C and regularly carry reports about people who have succumbed to the heat. Heat records were broken in Multan in June 1993, when the mercury was reported to have risen to 54 °C. In August the oppressive heat is punctuated by the rainy season, referred to as barsat, which brings relief in its wake. The hardest part of the summer is then over, but cooler weather does not come until late October.
Document 8: Chihuahua (state): The plains at the foot of the Sierra Madre Occidental is an elongated mesa known as Altiplanicie Mexicana that exhibits a steppe climate and serves as a transition zone from the mountain climate in the western part of the state to the desert climate in the eastern side of the state. The steppe zone accounts for a third of the state's area, and it experiences pronounced dry and wet seasons. The pronounced rainy season in the steppe is usually observed in the months of July, August, and September. The steppe also encounters extreme temperatures that often reach over 100 °F in the summer and drop below 32 °F in the winter. The steppe zone is an important agriculture zone due to an extensive development of canals exploiting several rivers that flow down from the mountains. The steppe zone is the most populated area of the state.
Document 9: Tornado climatology: The United States has the most tornadoes of any country. Many of these form in an area of the central (with some definitions including Southern) United States known as Tornado Alley. This area extends into Canada, particularly the Prairie Provinces and Ontario; however, activity in Canada is less frequent and intense than that of the US. The high frequency of tornadoes in North America is largely due to geography, as moisture from the Gulf of Mexico is easily advected into the midcontinent with few topographic barriers in the way. The Rocky Mountains block Pacific - sourced moisture and buckle the atmospheric flow, forcing drier air at mid-levels of the troposphere due to downsloping winds and causing cyclogenesis downstream to the east of the mountains. Downsloping winds off the Rockies force the formation of a dry line when the flow aloft is strong, while the Gulf of Mexico fuels abundant low - level moisture. This unique topography allows for frequent collisions of warm and cold air, the conditions that breed strong, long - lived storms throughout the year. This area extends into Canada, particularly Ontario and the Prairie Provinces, and strong tornadoes can also occur in northern Mexico.
Document 10: Bakersfield Municipal Airport: Bakersfield Municipal Airport is a city-owned public-use airport located three nautical miles (6 km) south of the central business district of Bakersfield, a city in Kern County, California, United States. The airport is mostly used for general aviation.

Formerly known as Jefferson County Airport or Jeffco Airport, the airport was renamed Rocky Mountain Metropolitan Airport on October 10, 2006 although it is sometimes referred to as Rocky Mountain Regional Airport, e.g. 2007-2012 county planning documents.
Document 12: Geography of Nigeria: With the Intertropical Convergence Zone (ITCZ) swinging northward over West Africa from the Southern Hemisphere in April, heavy showers coming from pre-monsoonal convective clouds mainly in the form of squall lines also known as the north easterlies formed mainly as a result of the interactions of the two dominant airmasses in Nigeria known as the Maritime tropical (south westerlies) and the Continental tropical (north easterlies), begins in central Nigeria while the Monsoons from the south atlantic ocean arrives in central Nigeria in July bringing with it high humidity, heavy cloud cover and heavy rainfall which can be daily occurrence lasting till September when the monsoons gradually begin retreating southward to the southern part of Nigeria. Rainfall totals in central Nigeria varies from 1,100 mm (43.3 in) in the lowlands of the river Niger Benue trough to over 2,000 mm (78.7 in) along the south western escarpment of the Jos Plateau.
Document 13: Raton Municipal Airport: Raton Municipal Airport (Crews Field) is 12 miles southwest of Raton, in Colfax County, New Mexico. The National Plan of Integrated Airport Systems for 2011–2015 called it a "general aviation" facility.
Document 14: Rodeo Municipality: Rodeo is one of the 39 municipalities of Durango, in north-western Mexico. The municipal seat lies at Rodeo. The municipality covers an area of 1,854.9 km².
Document 15: Mexico City: The area receives about 820 millimetres (32.3 in) of annual rainfall, which is concentrated from June through September/October with little or no precipitation the remainder of the year. The area has two main seasons. The rainy season runs from June to October when winds bring in tropical moisture from the sea. The dry season runs from November to May, when the air is relatively drier. This dry season subdivides into a cold period and a warm period. The cold period spans from November to February when polar air masses push down from the north and keep the air fairly dry. The warm period extends from March to May when tropical winds again dominate but do not yet carry enough moisture for rain.
