Atlantic hurricane seasons
2021, 2022, 2023, 2024, 2025

The 2023 Atlantic hurricane season was a hyperactive season in which 22 total storms formed, 8 of which became hurricanes, 6 became majors, 5 Category 4s and 3 Category 5s.

It had a late start in August, but due to the active late season full of weak storms the number skyrocketed. It was a destructive and deadly season, however most storms capable of causing massive damage missed land, with only Arlene making a major landfall. It was the first time a hurricane made landfall in Europe, with Arlene making landfall as a Category 4 storm, causing 57 billion dollars of damages and 51 fatalities.

The season had a late end, with Alpha dissipating over Central America on the second day of Christmas. Alpha was the deadliest storm, causing more than 2000 fatalities in Central America during the holiday period due to rain and mudslides.

The season had an unusually inactive Gulf Of Mexico, but the MDR was hyperactive, and the Carribean was a bit above average.

It was thought that due to the El Nino event of 2018 - 2023 the season would be inactive, but during winter it became neutral, and eventually flipped to a super Nina, which fueled the activity that would follow.

This season is one of only 7 to feature multiple Category 5 hurricanes. It had 3 - Don, Emily and Harold.

The season produced 243.6625 ACE units, 69.17 of those were produced by Hurricane Emily. It makes the season the 3rd most active since 1851, behind 2005 and 1933, and the second in the satellite era, only behind 2005. Emily came close to beating the single storm ACE record, but came a bit short. It also was one of five years since 1950 to have multiple storms above 40 ACE, with Don and Emily both reaching above 40.

This season started the 2023 - 2026 active La Nina streak.

Seasonal forecasts

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 National Hurricane and Climate Prediction Center, Tropical Storm Risk, the United Kingdom's Met Office, 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 1981 and 2010 contained roughly 12 tropical storms, six hurricanes, three major hurricanes, and an accumulated cyclone energy (ACE) index of 66–103 units. NOAA typically categorizes a season as either 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 are considered occasionally as well.

Pre-season outlooks

On December 5, 2022, TSR released their initial forecast of the season, calling for a below average season, with 5 named storms developing, 1 of them becoming a hurricane, and no storms reaching major hurricane status. They also predicted the ACE index to be below 30, due to an El Niño phase in the ENSO. On April 5th, the TSR updated their forecast to 4 named storms and no hurricanes or major hurricanes, due to apparently worse than expected conditions, and an ACE index below 15. NOAA released their prediction on the same day, predicting 15 named storms, 6 hurricanes, 3 major hurricanes, and an average or above average season, due to predictions calling for the El Niño to weaken or end. CSU also released their initial prediction, placing in between the TSR and NOAA with 9 named storms, 2 hurricanes, and 0 major hurricanes predicted, and an overall below normal season.

Mid-season outlooks

On June 1st, the CSU updated their forecast to 6 named storms, 1 hurricane, and no major hurricanes, based on yet worse conditions for hurricane development in the Atlantic. The TSR also updated their forecast, at 3 named storms and no hurricanes or major hurricanes, with the NOAA updating their forecast as well, at 11 named storms, 5 hurricanes, and two major hurricanes, with a normal to below normal season. On the 5th of July, UKMO released their only forecast for the season, at an extremely low rating of two named storms, two hurricanes, and no major hurricanes. The generally low forecasts were influenced by the present El Niño pattern. On the 1st of August, the NOAA updated their forecast, increasing the named storms by five to 16, the hurricanes by two to 7, and leaving the majors as is. On August 11th, the last updates were issued by CSU, calling for 9 named storms, 6 hurricanes and 2 majors, and TSR, calling for 8 named storms, 6 hurricanes, and 3 majors. In the end, the season outperformed all predictions.

Seasonal summary

wikipedia:Saffir-Simpson Hurricane ScaleThe 2023 Atlantic hurricane season officially began on June 1st, 2023. However, the first system, Arlene, did not develop until August 1st. It was a hyperactive season and the second busiest on record, as well as the third highest ACE producing season on record, in which 22 systems formed, all of them became storms, 8 of the storms intensified into hurricanes, and a further 6 of those hurricanes intensified into majors. Due to a La Niña, a phase in the ENSO, unfavourable conditions were produced over the eastern Pacific, and favourable conditions were produced in the Atlantic, which resulted in the unusually high activity observed in the Atlantic. Overall the season caused $58.844 billion in damage, a majority of that figure coming from one storm - Arlene, and more than 2270 deaths, a majority of that figure being caused by Alpha.

Tropical cyclogenesis began in early August, with Arlene developing on the 1st of August. It was not named until the next day, resulting in one of the latest hurricane season starts on record. From August 1st to very late October, the season featured nearly constant tropical activity, however most of the storms were weak and short lived. August was a very active month, with 7 named storms forming, including the most powerful storm of the season - Emily, which lasted well into September. September had average storm formation statistics, with 3 named storms forming, the most powerful of them being Harold, which gave a major scare to the East Coast as it threatened to make a major landfall on the East Coast, before eventually turning away. In October, 6 storms formed, which was way above the average for the month. The most powerful storm in the month was Jose, however it formed in the previous month. November had a record breaking 4 storms, breaking the previous record of 3 storms set by 2005. The most powerful of those was Sean, a high end category 1 hurricane. December tied the highest number of named storms in the month at 2, with 1887 and 2005. The most powerful storm of December and the last storm of the season, Alpha, was the first storm to get named using the greek alphabet since Zeta in 2005, and produced torrential rainfall in Central America around christmas as a minimal category 1 hurricane.

The 2023 hurricane season was an unusual occurence and tied or broke some records. For one, Arlene was a record breaker storm, becoming the northeasternmost major and category 4 storm in the basin on record, the northeasternmost tropical storm force or higher landfall in the basin's history, most powerful landfall in Europe as it was a category 4 at landfall, an unprecedented occurence, and the costliest storm in Europe, totalling about $57 billion. This was also the first time on record that a storm produced winds of any category above tropical storm in Europe as a purely tropical system. Meanwhile, Emily nearly became the highest single ACE producer in the Atlantic, with 69.17 ACE units. Alpha became the deadliest December storm in the Atlantic, easily setting the record at over 2000.

The season's hyperactivity was reflected by an accumulated cyclone energy (ACE) rating of 243.6625, which is the third highest ACE rating in the basin's history, only below 1933 and 2005. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is tropical storm strength.


Hurricane Arlene

Category 4 hurricane (NHC)
