I live in Palm Beach County. Just south of Palm Beach Gardens. I actually in West Palm Beach, the county seat.
Jobs:
Experience tells me, there are very few jobs available. What are available only pay minimum wage or slightly better.
Living Expenses:
Be glad you could get the free rent, food and transportation. It's very high. A rental on a 3 BR place around here or Palm Beach Gardens easily goes for $1800-$2000 a month. We live my mother-in law and I have a family of 5.
Weather :
Varies. We have lots of rain, lots of sun, lots of heat and high humidity. Wind every so often. In the Winter, it used to only go down to maybe the 50's, now we get down to the 30's. We do get the occasional hurricane, possible tornado and possible flash floods. We have also been know to have fire issues. The county is currently on a water restriction for the 3rd or 4th year. In spite of all the rain, we are still dry.
General stuff:
Mosquitoes are bad and they do spray 2-4 times a year. Crime is out of this world, but not as bad as other places. (Do not take this wrong, anybody please. I promise, I am not prejudicial at all.) When I left here in 1996, there was a joke that said, "Will the last American to leave Dade County, please bring the flag?" I returned here in 2009. Palm Beach County has had an "explosion" of foreigners. We are "overrun" with Mexicans, Puerto Ricans, Cubans, Haitians, Guatemalans, and I'm not sure what else. We have learned to adapt and deal with it, but it makes shopping and job hunting hard. They seem to get all of the jobs and are still on welfare.
Positives:
We do get the occasional celebrity here. There have been times that a President comes to town. It can rain in your front yard but not your back yard. Even though the Doppler radar shows rain covering the whole area, it's still hit or miss. My area doesn't get rain as much, but then an area just 3 miles from us gets rain daily. The beaches are wonderful. You may have to go through some trash left by careless people to get there. Also, there is no more free parking for the beaches here in my area. You have to pay for your parking. Up towards Juno Beach or so (Just north of Palm Beach Gardens) there is a fantastic park called Blowing Rocks. They have some of the best snorkeling opportunities available. (I only hope the hurricanes from 4 or 5 years ago didn't damage them too much.)
It is a great area, as long as you can deal with the diversity of cultures. There is not a big deaf community. (I am still trying to find more)
Let me know if you need any other information.
