Maps & Data

How cool does it usually get overnight during this month? Based on daily observations from 1991-2020, colors on the map show the long-term average minimum temperature, sometimes referred to as “the overnight low,” in 5x5 km grid cells for the month displayed. The map reveals the average of overnight low temperatures during the month over the previous three decades.

What is the long-term average temperature for this month? Based on daily observations from 1991-2020, colors on the map show the long-term average mean temperature in 5x5 km grid cells for the month displayed. The maps show mean temperatures—the arithmetic average between the highest and lowest temperature in a 24-hour period—averaged together over the month for the previous three decades.

How warm do afternoons usually get during this month? Based on daily observations from 1991-2020, colors on the map show the long-term average maximum temperature, sometimes referred to as the daytime or afternoon high, in 5x5 km grid cells for the month displayed. The map reveals the average of daytime high temperatures during the month over the previous three decades.

How much rain and snow usually fall this month? Based on daily observations from 1991-2020, colors on the map show long-term average precipitation totals in 5x5 km grid cells for the month displayed. The darker the color, the higher the total precipitation.

A digital archive of oral history interviews related to our changing environment, climate, oceans, and coasts. The entire database houses nearly 2300 unique oral histories as part of 118 distinct collections.

A one-stop shop for current, reliable, and useful information and resources related to drought conditions and associated risks.

How has the age of Arctic Sea Ice changed over time? Since the late 1900s, Arctic sea ice has thinned, and less sea ice has persisted in the Arctic over multiple melt seasons. The trend toward younger, thinner sea ice over time reflects warming temperatures in the Arctic. As older ice is thicker than younger ice, the reduced area of old ice also indicates a reduction in the total volume of ice.

Where is the chance for wildfires enhanced at this time of year? Shading on each map reflects how often fires with an area of 100 acres or larger were reported within 25 miles during a 24-year base period. The darker the shading, the higher the number of fires reported close in time to the displayed date.

How much rain and snow fell through the month? Colors show monthly precipitation totals across the contiguous United States. The darker the color, the higher the total precipitation.

NOAA's Geoplatform provides geospatial data, maps, and analytics in support of NOAA's mission through a GIS application using Esri's ArcGIS Online. Maps, Layers, Scenes, Apps, and StoryMaps are available to the public for browsing.
