Geography and climate
Honolulu is located at 21°18'32" North, 157°49'34" West (21.308950, -157.826182)GR1. While this is clearly in the tropics, the climate (temperature and humidity) is moderated by the mid-ocean location and some cooling achieved by the California Current that passes through the islands much of year. The average daily low and high temperatures in January are 65/80 °F (18/27 °C) and in July are 74/88 °F (23/31 °C). Temperatures exceed 90 °F (32 °C) only rarely, with lows in the 50's °F (15 °C) occurring perhaps once or twice in a year. The hottest temperature ever recorded in Honolulu was 95 °F (35 °C) on September 19, 1994 and the coldest temperature ever recorded was 53 °F (11.6 °C) on January 31, 1998, 1972 and 1948; January 20, 1969; February 1 and February 2, 1976; February 9, 1981; and February 12, 1983.
The Honolulu District is located on the southeast coast of Oahu between Makapuu and Halawa. The District boundary follows the Koolau crestline, so Makapuu Beach is in the Koolaupoko District. On the west, the district boundary follows Halawa Stream, then crosses Red Hill and runs just west of Aliamanu Crater, so that Aloha Stadium, Pearl Harbor (with the USS Arizona Memorial), and Hickam Air Force Base are actually all located in the island's Ewa District.
Most of the city's commercial and industrial developments are located on a narrow but relatively flat coastal plain, while numerous ridges and valleys located inland of the coastal plain divide Honolulu's residential areas into distinct neighborhoods: some spread along valley floors (like Manoa in Manoa Valley) and others climb the interfluvial ridges. Within Honolulu proper can be found several volcanic cones: Punchbowl, Diamond Head, Koko Head (includes Hanauma Bay), Koko Crater, Salt Lake, and Aliamanu being the most conspicuous.
Honolulu and Juneau, Alaska are the only two US state capitals that cannot be reached directly by road from the contiguous 48 States. Direct connections to these capitals require a boat or a plane.
