Is it ok to store 10 year expiry emergency water outside in the shade?

I have north facing balcony and wondering if it’s ok to store my boxes of emergency water outside, as they currently take up a lot of floor space in my bathroom.

It’s out of the sun, but it does get warm in summer I guess. But as it is sealed it should be fine? I’m wondering if there is any risk here I am not aware of

ETA: this is a bad idea. Thank you everyone !
