If there is moisture in the core, the temperature of that material will be different than solid glass laminate or dry core. After a cold night, when the daytime temp rises above freezing, the wet core will remain colder longer than the dry areas of the hull because the moisture being denser than balsa and air, will hold the cold longer before warming up.
It's good practice to check a cored hull on a day where the nighttime and daytime temperatures are thirty degrees apart. Like a common winter day in my area where the nighttime temperature drops below freezing and then the afternoon gets above 50. If you have wet core, any wet area will feel cold and actually show surface condensation next to dry areas. Mark it with a pencil for reference later.
