Hi Kay. Sourdough starter will keep comfortably up to about 80°F. The fact that it's a little runnier suggests that the humidity is being absorbed by your flour, causing it to be thinner. This is perfectly normal, so you can sprinkle in a little extra flour until it reaches the thicker consistency you're used to. We hope this helps! Annabelle@KAF
