It'll cause the spreading of the colonies that are growing on the agar surface if the condensed water falls on them. That's why usually the plates are inverted during incubation.

Bacteria love to grow in moist damp places - if you haven't noticed, condensation causes water droplets to form on the top of the lid and if you incubated the plate with lid on top when the water runs down the sides of the plate it can easily contaminate your culture.

What happens to a plate if agar is too hot?

You may kill your bacteria. To avoid this problem we "defrost" the agar in the microwave for 3-8 minutes (depending on how much you have) to liquefy it. It is important to loosen the cap of the agar container so that it doesn't explode in the microwave--never heat a closed system. When the agar comes out of the microwave it is too hot to plate with without the risk of killing your bacteria. Kepp the agar liquid by leaving in a 60 degree C water bath. When the temperature of the agar equilibrates with the bath it should be safe to use.
