Re: Longest streak without a tropical cyclone worldwide

I had noticed there had not been a storm for a bit but didn't realize it was that long. I needed to test something a few days ago on an active storm somewhere in the world within the past 30 days and I kept going back 6 hours and finally just jumped back to April. I didn't realize that it had really been that long.

Looks like perhaps 41 days is the record in recorded history, at least reliably. Going back 70 years you miss storms when there were no satellites.

From Jeff Masters post on May 15, 2012:

"Earth's longest tropical storm-free period in at least 70 years
The formation of Aletta ends a 41-day streak without a tropical storm anywhere in the world. According to the UK Met Office, the 41-day period storm-less period is the longest span Earth has gone without a tropical storm in at least 70 years. The last time there were as many as 38 consecutive storm-less days was in 1944. Prior to Aletta, the last tropical storm on the planet was Tropical Storm Daphne in the South Pacific, which dissipated 06 UTC April 3, 2012. April is usually is the quietest month globally for tropical cyclones. The long storm-less period comes in the midst of a very quiet two-year period of global tropical cyclone activity. According to Dr. Ryan Maue, who specializes in tracking global tropical cyclone activity, 2010 and 2011 saw a total of 146 global tropical cyclones--the lowest two-year total since satellite observations began in 1970. The 24-month period April 2010 - March 2012 had 141 global tropical storms, which is also a record low. That's quite a turnaround from 2004 - 2005, which saw near-record high levels of global tropical cyclone activity."
