If the old caulk was applied when the temperature was below 40 degrees F, then it is likely the caulk has lost its adhesion and is now cracking. Something to consider is that it's not just about the temperature in the bathroom, it's also the temperature of the caulk itself.
Use silicone caulk. Clean off all the old caulk and wipe the surface with denatured alcohol using cloth rags. Finishing and getting a nice bead is the key. Some use finishing tools like a Dap Cap, I prefer a finger but that works best for the experienced.

A well-applied bathroom caulk is supposed to last five years. If you're only a few years in and are seeing water where it shouldn't be or if you have gummy, cracking caulk, you know that something's afoot.
Reasons to Caulk Around a Toilet
Moisture Prevention: Without caulk around the toilet base, external water can seep under the toilet, leading to floor and subfloor damage over time. This is especially important in bathrooms with wooden floors, as prolonged exposure to moisture can lead to rot and structural issues.
Understanding mold growth
Caulking, with its porous nature, easily traps moisture, becoming a breeding ground for mold spores.
The International Plumbing Code requires caulk around the base of a toilet. You must use 100% silicone caulk where fixtures meet the wall or floor. Here are a few of the primary reasons it's required, and you should take the time to properly seal toilets above and beyond basic code requirements.
Most toilets are white and most bathrooms floors are white. Always chose white. White caulk will give your bathroom floor a seamless integration to the toilet which is what you want for your bathroom. Apart from time that, clear caulk tends to turn into a yellow color with time.

Typically, you should use caulk in bathrooms due to its flexible, waterproof, and non-porous composition. Caulk is also easier to remove and replace when necessary, which will minimize damage to your fixtures.
In order to fix this problem, you may need to use a different type of caulk or even just apply a wider bead of caulk. Similarly, it's not uncommon that the gap isn't wide enough. In this case, you may need to use a thinner bead of caulk or even just apply more pressure while smoothing it out.
The overarching reason why new caulk should never be installed over old caulk is because it simply does not produce long-lasting results. The reasons why depend on what has happened to the previous caulk line. In the case of caulk that has gotten moldy, recaulking over this material will not stop the mold problem.
If you notice peeling or flaking caulk, it's time to replace it. Soft or spongy caulk is a sign that it's reached the end of its useful life.
The paint dries first, forming a film. As the caulk dries, it shrinks and causes the paint film to stretch and crack.
Over time, caulk can dry out and shrink. It may pull away from the surfaces to which it was applied, or it may become brittle and crack. This deterioration compromises the seal, allowing water to leak through.
