Safe temperature range to storage reef tank salt water

[Braveheart!]

I’m going away on vacation and have an experienced individual who can do water changes. It there a temperature range the salt water should be kept at. I would think a little cooler would be better. Currently, I keep it stored in the garage for about two weeks, but it can get in the high 80s on hot days. Thanks for any input. Also and pros and cons.

I've kept water in the garage and in the summer here the water can get up into the low 90s. Never had any issues but just a pain to find a way to cool it down for use. Much easier if it's colder since you can just throw a heater in and warm it up.
