weather and guitars

[Antonio Cotichini]

I'm not keen in meteorology. Which is the alert point in humidity and temperature for acoustics? In these days it's very hot, here in Italy. In my area it's 30/34 °C (86/92 °F), 51% humidity. Any danger for guitars? And... if it's possible to reduce humidity putting silica gel in the hardshell case, how can one add humidity (if needed)? Shower?

I had brought home a new Chinese guitar that needed the bridge re glued and as my bridge clamps were at home I brought it home. I forgot about it for several days and when I went to use the car I found it in the back seat with all the windows closed. I had parked it under the apple tree in the shade in the afternoon.
IT was in the sun in the morning and should not have gotten to hot but it was. I should have gotten a theromator to see how hot it was but didn't. The bridge has shrunk and cupped up so I had to remove it to reglue.
The rest of the guitar was OK.

I don't think you have anything to worry about, Antonio. What you describe are pretty good building conditions, actually. Makes hide glue alot easier to work with. Just don't stick it in a black case in a car parked in the sun. You probably won't be as lucky as Ron.
