Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PDT Tue Aug 1 2023

For the eastern North Pacific, east of 140 degrees west longitude:

Three tropical cyclones, Hurricane Calvin, Tropical Storm Dora, and 
Tropical Depression Four-E, formed in the basin for the month of 
July.  Shortly after passing southwestern Mexico, Beatriz dissipated 
on 1 July, while Adrian became a post-tropical remnant low well to 
the southwest of the Baja California Peninsula on 2 July. Dora 
formed on the last day of the month, and was still a tropical 
depression at the end of the month. 

The formation of three tropical cyclones is below the long-term 
average for July.  The number of named storms in the basin so far in 
2023 (4) is below the long-term average of 5 or 6 through July.  
However, the season had a late start, with Adrian marking the 
second-latest formation of the first named storm of the season 
during the reliable period of records (1971-2023).

In terms of Accumulated Cyclone Energy (ACE), which measures the 
combined strength and duration of tropical storms and hurricanes, 
2023 is well below the long-term (1991-2020) average.
