A few guidelines on the sky condition code for IODs.
Usually, if the moon is full, the best the condition should be reported is fair. Similarly if it is very gibbous the best condition would be good.
Although the guidelines already tell you about cloudiness, it does matter whether these are high thin static clouds, or fast moving low stratus clouds, or fog or haze. One way to approach this is to compare the interference of the clouds of whatever type to a similar Moon phase.
