Fog: The real Jersey is the closest Channel Island to France, and it does get fog rolling in from the French coast, mostly in the summer.Generally, if it snows at all, it will be too warm for it to persist for long. However, in order for there to be a more authentic often-overcast “feel” here, in the preset fog is possible year-round. In autumn, winter, and spring, it will only happen when the temperature is 50F/10C or below and is set for longer durations, to contribute to gloom in colder times of the year when it isn’t raining.
In summer, it can happen at any temperature but durations are short.
