Hey guys. I haven’t been playing much (or maintaining) my old Czech double bass over the last handful of years.  in spite of using a humidifier, I have a couple of cracks and open seams. Is it better to repair the bass while the weather is still cold and dry, or wait a handful of weeks until spring has really sprung?
I would think that, since weather is always changing - and will change again - it doesn't matter whether you do it now, or wait. But I've been wrong before!
Depending on where you are, I chose to wait out the cold snap we had here that popped my seam. I don't think you need a wait out a whole winter or anything.
I like doing crack repairs and soundpost adjustments in the dryness of winter because as the humidity rises, the post gets looser not tighter. Same goes for lateral expansion of the top/back plates. Which means that you're more likely to pop a seam than open any cracks. Just my .02
