Climate Zones. The earth's tilt, rotation and land/sea distribution affect the global weather patterns we observe. While the weather varies from day-to-day at any particular location, over the years, the same type of weather will reoccur. The reoccurring "average weather" found in any particular place is called climate. Choose Location. Choose Location displays the Lower 48 States as the default location. You can change the location by clicking the Choose Location drop down menu to switch between Lower 48 States, Alaska, Hawaii, and Puerto Rico.
The new map is generally one 5°F half-zone warmer than the previous map throughout much of the United States. This is mostly a result of using temperature data from a longer and more recent time period; the new map uses data measured at weather stations during the 30-year period 1976-2005.
Weather zones usa. Planting zones are areas you can find on a growing zone map that show exactly which plants are best suited to thrive in your given area, or zone. When shopping for new plants for your garden landscape, the terms “plant hardiness zones,” “growing zones” and “planting zones” may at first seem a bit confusing. Understanding the USDA planting zones you live in can mean the difference between success and failure in your garden. Planting plants, vegetables and flowers that are appropriate for your US growing zone will make sure that your garden is happy and healthy year after year. Below is the USDA planting zones map, also known as the USDA Hardiness Zone map. A hardiness zone is a geographic area defined to encompass a certain range of climatic conditions relevant to plant growth and survival.. The original and most widely-used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by annual extreme minimum temperature. It has been adapted by and to other countries.

Current weather in United States, with temperatures in 1021 cities, including high and low temperatures for the country. How Many Time Zones Are There in the US? There are 9 time zones by law in the USA and its dependencies. However, adding the time zones of 2 uninhabited US territories, Howland Island and Baker Island, brings the total count to 11 time zones. The contiguous US has 4 standard time zones. In addition, Alaska, Hawaii, and 5 US dependencies all have their own time zones.
We have provided 2 differing Climate zone maps of the US with varying levels of detail. ClimateZone Maps of United States: Hardiness Zone Map The USDA Hardiness Zone Map divides North America into 11 separate planting zones; each growing zone is 10°F warmer (or colder) in an average winter than the adjacent zone. Northern Arizona and New Mexico, central and northern Nevada and most of Utah (outside higher mountain areas) have a temperate semi-desert to desert climate, but with colder and snowier winters than in Phoenix and similar areas, and less-hot summers (as at Salt Lake City, Utah).Summer high temperatures often reach the 90s, but low temperatures drop into the low 60s and even 50s. Stay ahead of the weather with our local, national and world forecasts.
How are climate zones divided in USA & Canada? Using information gathered from 4,775 US weather sites, in the early 2000s, the U.S. Department of Energy’s Pacific Northwest National Laboratory created a simplified map separating North America into 8 general climate zones based primarily on temperature. It was then divided into three moisture. Surface Weather Upper Air Marine and Buoy Reports Snow Cover Satellite Space Weather International Observations.

The two most commonly referenced hardiness zone maps are those produced by the U.S. Department of Agriculture ( USDA ) and Natural Resources Canada ( NRC ).
The USDA map is the one most gardeners in the eastern United States rely on, and the one that most national garden magazines, catalogs, books, websites and nurseries currently use. This map divides North America into 11 separate zones. Each zone is 10°F warmer (or colder) in an average winter than the adjacent zone. The 2012 USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Given that the contiguous United States spans the width of North America, it’s not surprising that the country has no fewer than nine unique climate zones.While weather can vary within these regions depending on geographic features such as coastlines, mountains, and deserts, overall these regions are climatically consistent.
