The hamlet is also home to Long Island MacArthur Airport, which is owned and operated by the Town of Islip. The New York Air Route Traffic Control Center is located at the airport.
History
The name "Ronkonkoma" comes from the nearby Lake Ronkonkoma, which in turn comes from an Algonquian expression meaning "boundary fishing-lake", also earlier written as "Raconkumake" and "Raconkamuck."[3][4]
Ronkonkoma was the terminus of the first road in the United States designed exclusively for automobiles, the Vanderbilt Motor Parkway, constructed by a consortium of investors called the Long Island Motor Parkway, Inc.; the consortium was led by William Kissam Vanderbilt II.[5]
In May 1943, Long Island MacArthur Airport – located within the hamlet – was activated.[6] The airport would begin serving scheduled commercial passenger flights in 1960, when Allegheny Airlines commenced service at MacArthur that year.[7] The Town of Islip announced plans in 2025 to construct a new passenger terminal on the north side of the town-owned airport, adjacent – and connected – to the Ronkonkoma LIRR station.[8]
In 1982, the Town of Islip Foreign Trade Zone – located adjacent to MacArthur Airport – opened.[9][10] It is a magnet site for Foreign Trade Zone 52 and, as of 2026, is the only designated foreign trade zone on Long Island outside of New York City.[11]
Since 1988, the community has been the end of electrification along the Long Island Rail Road's Main Line.[12] The portion of the Main Line between the Hicksville and Ronkonkoma stations is known as the Ronkonkoma Branch.[12]
In 2017, then-Governor Andrew M. Cuomo announced the groundbreaking of a major development project to create a "Ronkonkoma Hub" adjacent to the Ronkonkoma LIRR station in Lake Ronkonkoma, straddling the north side of its border with the Ronkonkoma CDP (and, in turn, the Brookhaven–Islip town border); at the time of the announcement, the total cost of the project was estimated to be $650 million.[13] This development project, known as also known as Station Yards, would spur economic development on both sides of the tracks, in Ronkonkoma and Lake Ronkonkoma.[14] As of 2026, the total cost of the project is expected to be approximately $1.2 billion.[14]
Geography
According to the United States Census Bureau, the CDP has a total area of 8.1 square miles (21.1 km2), of which 0.35 square miles (0.9 km2), or 4.07%, is covered by water.[2]
The Lake Ronkonkoma kettle lake is located entirely within Ronkonkoma – not the neighboring, eponymous hamlet.[15]
Climate
Under the Köppen climate classification, Ronkonkoma has a humid continental climate (Dfa), with some maritime influence, or under the −3 °C or 26.6 °F threshold a humid subtropical climate (Cfa); it is part of USDA hardiness zone 7a.[16] The normal average monthly temperature ranges from 31.9 °F (−0.1 °C) in January to 75.0 °F (23.9 °C) in July; on average, there are 16.3 afternoons where the temperature remains at or below freezing and 8.3 afternoons with a high at or above 90 °F or 32.2 °C annually; the last year to not reach the latter mark was 2014. Temperatures below −5 °F (−20.6 °C) or above 100 °F (37.8 °C) are rare, and were last seen respectively on January 7, 2018, at −5 °F or −20.6 °C and July 22, 2011, at 100 °F or 37.8 °C. The record low is −14 °F or −25.6 °C, set on February 13, 1967, while the record high is 104 °F or 40 °C, set on July 3, 1966.

Snowfall averages 31.8 inches or 0.81 metres per year, falling almost entirely from November to April.[16]
