Unless you plan to holiday in the Caribbean, for more than a couple of weeks, November is not a good month to retire. Days are dark, cold and miserable. You may as well be at work, explaining to colleagues that you are not taking on new work because you're retiring in a few months. Retire in Spring and adjust to your new found freedom. There is much more to retirement than weather and money. The psychological adjustment can be difficult.
Disclosure: I retired a couple of weeks after passing the 40 years, in November, but went straight to a part time gig, which I am struggling to give up, 4 years later. Want to retire, again, but hesitate to pull the plug!
