Source: jsc.nasa.gov
Boston’s total area:  232.1 square kilometer
Land area:   41.2 square kilometers
Area covered by water:  106.7 kilometers
Geographical Coordinates of Boston:  42.358N and 71.06W

Boston is located on the Shawmut Peninsula, found in the merging of the two rivers: Charles and Mystic rivers. The rivers flow into Boston's inner harbor and then into Boston Harbor itself. The hilly peninsula of Shawmut is entirely isolated from the mainland by marshy swamps. A planned and a compact city, Boston has an altitude of 5.8 meters above the sea level. Bellevue Hill, the highest point in the city, is 101 meters above the sea level.

The suburbs of Boston include the cities and towns of Winthrop, Everett, Somerville, Brookline, Needham, Canton, Milton and Quincy. Greater Boston is the name given to Boston and its suburbs. The Back Bay and the South End neighborhood of Boston are built on reclaimed land. The hills were leveled to fill in the marshlands.

River Charles separates the proper city from Cambridge, Watertown and Charlestown. The Neponset River in Boston separates the southern neighborhoods from the cities of Milton and Quincy. Mystic River determines the boundaries between Chelsea and Everett, while Boston harbor separates East Boston from the proper city.

Low rise brick or stone buildings, with Federal style architecture are found in Boston’s downtown and neighborhood areas. Modern high rise buildings are seen in South Boston Waterfront and Back Bay. Located in downtown, the Prudential Center and John Hancock Tower are two of the tallest buildings found here, which are major landmarks in Boston skyline.

The John Hancock Tower is in the center, Boston Common is at the upper left, and the Financial District is beyond the Common and Hancock. The major road to the right is the Massachusetts Turnpike (I-90), which connects to I-93 through the South Bay Interchange at the upper right. At the top right is Logan International Airport, which is across inner Boston Harbor.

Climate

Moderate climate is in between the months of April to September. Fog and humidity are by-products of Boston's proximity to water. Rain is frequent throughout the spring and summer, while snow falls regularly throughout the winter, making Boston one of the nation's wettest cities. Nearly 108 centimeters of snowfall are recorded annually in Boston. Atlantic Ocean breezes keep Boston's climate relatively mild compared to other cities in the northeastern United States. But those same Atlantic breezes help rank Boston among the country's windiest cities and occasionally blow into full-fledged storms called "nor'easters."

Average Temperatures: January, 29.3° F; July, 73.9° F; annual average, 51.6° F
Average Annual Precipitation: 42.53 inches of rain; 42.6 inches of snow
