Fog 🌫️

Multiple layers of soft, wispy clouds rendered in light gray or white, stacked to suggest dense fog obscuring visibility. The design emphasizes haziness and reduced clarity, with clouds appearing almost cloud-like and ethereal rather than fluffy and defined.

People use this emoji when conditions are literally foggy—morning fog, sea fog, or visibility-reducing atmospheric conditions that affect driving or outdoor activities. It's common in weather reports from coastal areas or mountainous regions where fog is frequent. Safety-conscious drivers might use it to explain why they're driving slowly or need to postpone travel.

Figuratively, fog works for confusion or unclear situations: "the details are still foggy," "I'm in a fog," or "my mind is foggy." It's less energetic than stormy weather emoji, lending itself to contemplative, hazy, or uncertain messaging. It also appears in poetic or atmospheric social media posts, especially from scenic locations.

Designs are consistent across platforms, maintaining that soft, layered appearance. Unlike dramatic lightning or tornado, fog is quieter and more subdued. Approved as part of Unicode Emoji 0.7 in 2010, this weather icon has remained steadily useful for both literal conditions and metaphorical haziness.
