Sunflake, Sunbird ?
 

If a snowflake is someone who only comes down for a few months (and usually rents) and a snowbird is someone who comes down for 5 to 6 months (rents or owns). What is a Florida resident who owns and claims this as their legal address but leaves for June July and August. I do not consider myself a snowbird as I am now a resident of Florida but I am planning to avoid the mid summer bake. So what do you call me.

Another friend and resident of the Villages...welcome! Labels separate, don't you think?

Smart.

How about Seasonal, I am down here for 6+ months and rent then go back to my beautiful northern Michigan, I love the fact that I have the best of both worlds ...Just an observation do we really need the labels? Then again in my area {resort town} we call vacationers Fudgies LoL

We call ourselves Seasonal Residents. We spend winters in our home in The Villages.
We spend summers in Canada where it's cooler.

First of all I call you smart! Years ago after an aunt and uncle who had resided in Towson, MD their whole lives bought a home in Winterhaven, FL. I used to drop by and visit them - but never in the summer. Over time I got to know a couple of successful local businessmen who spent their summers elsewhere, one in an RV, the other in a second home in the NC mountains. Neither one was fond of central Florida summers.

I have heard people who split their time between two homes referred to as splitters so that is what I call myself. Since splitter is not descriptive of weather driven change of residence perhaps another term would be more appropriate to the OP's circumstance.

I would call you LUCKY!

Snowflake is an owner who floats in and out as they please to their home. I am a snowflake. Other half reverse snowbird leaves in and out during high season. That's dance competition season, and you can never miss a performance

depends on where you are spending the summer

I call them "Summer Fleas" ... they flee for the Summer to cooler climes, and, smart they are.

How about Fair Weather Frog?

You have Florida residency/domicile but hop out of Dodge when the weather turns hot and humid.

Humiditybird.

The summer temperature in Florida isn't the problem - it's the high humidity with the 90 degree temperature that makes it uncomfortable.

Summer fleas sounds good. It is not about labels per say. People were making up a chore duty schedule for glass fusion and were asked to notify if we were snowbirds. Someone replied she was a full participating member and didn't consider herself a snow birds as she only leaves for three months, where as many members are only here for three months, which made me think.
