If you read Al's sticky above, he notes that cold weather is a great time to check the hull since moisture stands out when the hull is cold.

I did read it. It only applies to thermal imaging. Not all surveyors have this.
I don't see how, using a moisture meter, you can check a frozen hull. But then I am not a surveyor nor do I have any experience with a moisture meter and fiberglass, which brought be to post the question.

Frozen water never gets below its freezing temperature under normal circumstances. The rest of the hull will go to the ambient temperature thus differentiating it on the thermal image.
Kind of like spraying water on the oranges when a deep frost is expected.

Hello to all, sorry for the delayed response. Seems I've become quite busy early on this season.
RickB is correct in his statement regarding the cold weather findings. It is much harder to get good readings with a standard moisture meter when moisture intrusion has become frozen. Expansion of a wet core that is frozen will create crazing in the gel-coat in some areas. Thermo imaging is the best way to detect problems. Be careful tho, there are surveyors that buy low end cameras and don't have the training to know how to use them! Ask a lot of questions before hiring someone to survey your vessel.
