I cant speak to the science on the subject but i always felt like keeping my clubs out of harsh temperatures (except while playing) was beneficial. I worry that the epoxy between head and shaft would suffer the most. Also the rubber grips tend to be effected. Probably not significantly but after all, I wouldn't make my kids sleep in the garage and my Titleists are my "babies".

I don't leave my main bag in the garage in cold temps, but the other few bags of clubs that are out there, which I use to hit in the backyard throughout the winter, have not seemed to show any sign of even minor damage.

On the other hand, leaving them out there in the summer when the temps can get to baking-type temps, or leaving them in your trunk is NOT good for the grips or the epoxy which adheres the heads to the shafts. Epoxy can't handle excessive heat. Applying heat to the hosel to help separate head from shaft when reshafting is a common approach. So, it makes sense to not let them get too hot.

BTW, you don't want to soak them in water either. That too will break down the epoxies over time. Epoxies are typically repellent of water, but not impervious to it. (I worked in the marine industry on boats for many years using epoxies in many different construction applications. Certainly some epoxies are better than others for use around water, but I would guess those used for most golf club assemblies are typically not marine grade.) I think I have digressed from the original question. Sorry.

It is definitely recommended to store balls away from freezing or excessive high temperatures. Unless you play in sub-freezing weather, why not keep the clubs inside? The grips won't be as hard while warming to 37 degrees and the clubs will flex better. Not that you'd hit the mat fat, but more flex won't transmit as much shock to your arm joints.

Well I keep my clubs in my garage and felt nothing changed. I do think of them when it gets really cold and hot. But the change in weather is greater outside. Here in Texas we don't get that cold. When it is hot my garage is does not get as hot as outside. Now I do not keep my clubs in the trunk. I do not cover the hosel with hot water. Just dip the club itself and then take them out and wipe them. But you guys have me thinking.

Extreme cold and heat is not good for the glue between head and shaft, or the grip. That being said, I never had an issue with previous clubs being kept in a storage building with no climate control for years (then I recently switched to Titleist).

My Titleist's stay in my walk in closet. I want to see them when I wake up and when I go to bed. I want to know that they are ok and comfortable; like a child or beloved pet. haha

Thanks Sam. I didn't want to be the only one who treats his clubs that way.

Trust me Dale, you aren't!

Mine sit next to me in their comfy Titleist mid-staff bag, right at my desk all day. Well, at least they sit there when they are not out on the course with me, working their cute little bottoms and faces off on those winter days here in Maryland on which it's warm enough to play. (Only 2 days so far in 2018, but 3 more on tap beginning Friday, when temps are forecast to get over 40 degrees. Woo hoo!)

I love my full bag of Titleists. Some think I'm a bit nuts for the over-the-top care I heap on them. That's why I spend lots of time here at Team Titleist. You guys kinda understand.

I'm with Sam and Dale. My playing clubs are in our walk-in closet to keep them at room temps. That helps both the clubs and the balls. I do have a set of older (2008) AP1s and a couple of older putters in a bag and travel case in the garage. I don't really play these much so it doesn't matter if they get a little cold/warm. If I do plan to use one or two for a particular reason, I will bring them in the house to get them to normal temps. Fairways and greens.

Here in Idaho, I have played in 20 degree weather. I keep a hand warmer in my pocket with two balls and tees. Warm tees are easier to stick into the frozen ground. Also there's nothing like watching your perfectly place approach shot bounce off the green because it's frozen. Well I too treat my clubs like my babies as well. They sit in my office until it's time to play. I have seen my buddies clubs get mess up, grips, glue and what not, due to extreme weather.

I'm with all of these guys above. I especially feel strongly that it is not good for your grips whether they are rubber or leather. Extreme temperatures over time can crack and deteriorate the grip. That is why my clubs are always inside. With that said I have left my clubs in my trunk overnight when the lows are in the 60's. But only for one night. All of these comments above are excellent suggestions coming from experience and knowledge.

I am in agreement with the answers above. My clubs are in my closet during the winter. I don't want to sit in the garage during a Chicago winter, so I will not make my clubs do that either.

I to am a fellow Clevelander and I always keep my bag in the garage. I'm sure it can't be any worse than keeping them in the trunk of the car all summer. Besides being able to see them every day as I walk by gives me hope that winter will not last forever. This at least helps with the mental game!
Get them out this weekend!!! We might see 40°!!!
Those of you in the south have no idea how exciting a sunny 40° day in January can be.

i keep my clubs in house....i feel they are an investment..i mean if you think about it, you got about $2K worth of equipment. As for hitting....when it gets cold...(i.e. close to freezing)...i still like to go out and swing a club....i leave my driver, woods at home...although the stalls are heated....the balls are usually like rocks....why take chance with woods. Usually just take PW....9 or 8...7....just really to stay loose...and try to keep part of swing in a groove.....that is my take on cold weather

Mine stay in the house beside my dresser, I learned in high school to not leave clubs in the trunk & garage as I had an issue with 2 of the woods. So ever since then I kept my clubs indoors in a more stable environment.

I keep my golf balls inside after hearing to do so from the Titleist engineer at Pinehurst. My clubs...they stay in the car through SC summers and winters. Never had an issue. I do park in garages though at home and work...so my vehicle may not get as hot or cold as being truly outdoors.

Here in Colorado, I've pulled them inside once it has dipped below 50 degrees where they're nice and warm preparing to fly out the Phoenix Open next week! Who's gonna be out there?
