I am assuming that the paintings are on canvas.
If so, they respond very quickly to fluctuations in T and RH, as they are
thin. I agree with your assessment that moving them twice may pose more
risks than leaving them in acceptable RH conditions with 80 or 90 degree
temperatures, particularly since you did not provide T and RH info on where they
would be going. Remember, it was not all that long ago that we did not
have air conditioning, so all paintings except the most modern ones have
been through temperatures like that many times. Good luck.

Subject: [MUSEUM-L] Oil Painting
Question
Hello all-
I need some advice on the dangers of heat to oil paintings.
Everything I have found seems to suggest that high humidity and fluctuations
in heat and humidity are the biggest concerns. We are trying to decide if we
should move some paintings from a building where the air unit is
non-functional. The air unit is being repaired, but it will take three weeks
for this to happen. My view is that there is more potential for damage by
moving them twice in three weeks than just letting them be. The humidity
in the building is within acceptable range but the temp is in the 80s and 90s
at times.
I welcome your words of wisdom and advice.
