Southern New Jersey Climatological Data
EFFECTIVE 10/26/01, TABLE 1 WILL NO LONGER BE UPDATED. USERS OF CLIMATOLOGICAL DATA ARE REFFERED TO THE NEW JERSEY CLIMATOLOGIST WEBSITE, WHERE THE SAME INFORMATION CAN BE FOUND: http://climate.rutgers.edu/stateclim_v1/data/index.html
The data in Table 1 are the means from the National Weather Service's Southern New Jersey stations, after conversion to metric units.
Table 1. South Jersey Mean Monthly Temperature (C) and Total Monthly Precipitation (mm) for All Weather Stations, by Year, 1991-2001. The first row for each year is the temperature, and the second row is the precipitation. "Ann." means Annual, and is the mean annual temperature and mean total precipitation.| Year | JAN | FEB | MAR | APR | MAY | JUN | JUL | AUG | SEP | OCT | NOV | DEC | Ann. |
