Summary
Two named storms occurred across the globe in June, which was below the 1991-2020 average of 5.5. One of those reached tropical cyclone strength (≥74 mph), and one reached major tropical cyclone strength (≥111 mph). The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was about 20% of the 1991-2020 average for June.
The Atlantic basin was the only basin that saw tropical cyclone activity during the month of June. Two named storms occurred during the month, which is above the average of about one named storm per season since 1991. The first storm, Tropical Storm Alberto, peaked as a moderate strength tropical storm with winds of 50 mph and a minimum central pressure of 993 mb. The storm made landfall in northern Mexico and brought gusty winds and flooding rains to the region. The second storm, Hurricane Beryl became the first category 4 hurricane observed in the Atlantic Ocean during the month of June. Later in July peaked as the earliest category 5 hurricane on record with winds of 165 mph and a minimum central pressure of 934 mb. Hurricane Beryl made landfall in Carriacou, Grenada as a powerful category 4 hurricane and caused extensive and very severe damage across the Windward Islands before moving further into the Caribbean as the calendar turned to July. Hurricane Beryl is only the third major hurricane on record during the month of June.
No other storms formed globally during the month of June, which is very unusual for the month. No tropical cyclones were active in the East or West Pacific during the month, which is tied for the record least activity in both basins for June. Typically two storms form each June in the West Pacific and two more form in the East Pacific during the month. This is only the second time since 1971 (2016 being the other) that the East Pacific had no activity before July. Additionally, no tropical cyclones formed in the North Indian Ocean during the month of June, which is slightly below the long term average of 6 every 10 June’s. No storms formed in the Southern Hemisphere during June. The lack of activity is typical for these basins during the month of June.
The end of June marks the end of the southern hemisphere tropical cyclone seasons (South Indian, Australian, and Southwest Pacific). The South Indian tropical cyclone season saw thirteen named storms, of which five reached tropical cyclone strength, and two reached major cyclone strength. The South Indian tropical cyclone season was tied for the 4th most named storms on record, with a typical season seeing between ten and eleven named storms. The South Indian ocean saw slightly fewer tropical cyclone and major cyclone strength storms than is typical. A typical South Indian ocean tropical cyclone season sees 6.1 tropical cyclone strength and 3.5 major cyclone strength systems, respectively. The strongest storm of the season was Very Intense Tropical Cyclone Djoungou, which peaked with winds of 135 mph and a minimum central pressure of 942 mb.
The Australian tropical cyclone season saw ten named storms, of which six reached tropical cyclone strength, and three reached major cyclone strength. A typical Australian tropical cyclone season sees 10.6 named storms, 4.8 tropical cyclone strength storms, and 2.4 major cyclone strength storms. The season had a near average number of named storms and major cyclone strength storms, but had a slightly above average number of tropical cyclone strength storms. The strongest storm of the season was Severe Tropical Cyclone Jasper, which peaked with winds of 135 mph and a minimum central pressure of 937 mb.
The Southwest Pacific tropical cyclone season saw six named storms, of which two reached tropical cyclone strength, and one reached major cyclone strength. A typical Southwest Pacific tropical cyclone season sees 7.0 named storms, 3.8 tropical cyclone strength storms, and 1.9 major cyclone strength storms. The season had a near average number of named storms, but had a slightly below average number of tropical cyclone and major cyclone strength storms. The strongest storm of the season was Tropical Cyclone Lola, which peaked with winds of 135 mph and a minimum central pressure of 941 mb.

Data Description
The data in this report are derived from NCEI's IBTrACS dataset (Knapp et al. 2010; Schreck et al. 2014). IBTrACS tropical cyclone track and intensity data from agencies and sources around the globe. In this report, data from NOAA's National Hurricane Center (NHC) are used for the North Atlantic and East Pacific. The other basins use data from the U.S. Military's Joint Typhoon Warning Center (JTWC).
Historical values use the "best track" data that have been analyzed by forecasters after the season using all available data. Operational procedures and observing systems have changed with time and between regions, which makes these data heterogeneous. Intensity data are generally the most reliable since the early 1970s in the Atlantic (Landsea and Franklin 2013) and since the mid-1980s in other regions (Chu et al. 2002). The number of short-lived storms (≤2 days) has also increased since around 2000 due to improvements in observations and analysis techniques (Landsea et al. 2010).
Values for the current year are provisional values from the operational forecast advisories. IBTrACS obtains these from NCEP's TC Vitals, the NCAR Tropical Cyclone Guidance Project, and NHC provisional data. These values are subject to change during the post-season best track analysis. They also only include 6-hourly storm fixes, which means they may miss special advisories at landfall, peak intensity, etc.
The tropical cyclone seasons in the Southern Hemisphere begin in July and end in June, while the Northern Hemisphere seasons are counted from January to December. Storms are counted in all basins, months, and years in which they occur, which means some storms may appear more than once. However, the global totals only include each storm one time.
