The 2023 Atlantic hurricane season is an upcoming event in the annual tropical cyclone season in the Northern Hemisphere. The season officially begins on June 1, 2023, and ends on November 30, 2023. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean (over 97%). The National Hurricane Center (NHC) will begin issuing regular Tropical Weather Outlooks on May 15, 2023, about two weeks prior to the start of the season.

In advance of, and during, each hurricane season, several forecasts of hurricane activity are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States National Oceanic and Atmospheric Administration (NOAA)'s Climate Prediction Center, Tropical Storm Risk (TSR), the United Kingdom's Met Office (UKMO), and Philip J. Klotzbach, William M. Gray and their associates at Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to NOAA and CSU, the average Atlantic hurricane season between 1991 and 2020 contained roughly 14 tropical storms, seven hurricanes, three major hurricanes, and an accumulated cyclone energy (ACE) index of 72–111 units. Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 39 mph (63 km/h).[2] NOAA typically categorizes a season as above-average, average, or below-average based on the cumulative ACE index, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is sometimes also considered.[2]

Storm names[edit]
The following list of names will be used for named storms that form in the North Atlantic in 2023. The names not retired from this list will be used again in the 2029 season. This is the same list used in the 2017 season, with the exceptions of Harold, Idalia, Margot, and Nigel which will be used for the first time (if they form) after they replaced Harvey, Irma, Maria, and Nate, respectively.
