NWS: Average Temperatures And Rainfalls Increased In Daytona Beach


Daytona Beach, FL - Recently released data showcasing the new "climate normals" for Daytona Beach shows the area saw more rainfall and higher temps between 1991 and 2020.

According to the National Weather Service (NWS) office in Melbourne—the source of the data—the World Meteorological Organization (WMO), of which the United States is a member, requires each member nation to calculate 30-year meteorological averages at least every 30 years. The WMO also recommends that member nations provide an update each decade.

This means that data collected by the NWS between 1981 and 2010 will now be replaced with the averages over the 1991-2020 period. The data concerns "climate normals," which is the 30-year average of a climatological variable's measurements, such as temperature and precipitation.

Climate normals are obtained from weather and climate observations captured by weather stations in order to put today's weather into a "historical context," per the NWS.

In the 1991-2020 period, Daytona Beach saw an increase in max temperatures pretty much across the board when compared to the values captured within the 1981-2010 time period. Average max temperatures in July, however, remained unchanged. The highest change seen on the table came in December, where 1991-2020 was found to be 1.1 degree hotter than the average max temperature recorded in the 1981-2010 period.

Data from meteorologists also indicates that the average minimum temperatures of 1991-2020 increased over those found within 1981-2010. The highest change in that category also came in December, where the average minimum temperature of 1991-2020 was found to be 1.6 degrees hotter than 1981-2010.

The majority of rainfall totals in the 1991-2020 time period also increased over 1981-2010's totals, but there were some minor dips found within the data too. The largest increase in rainfall came in June where 1991-2020 was found to have 1.11 more inches of rain compared to 1981-2010.
