When Did It Snow in Miami, Florida?

Rare Snow Events in Miami

Snow in Miami is exceptionally uncommon but has occurred during rare cold outbreaks. The following entries summarize the most notable measurable snow events documented in the area, focusing on dates and observed accumulation. Most events produced only trace amounts, but a few stands out for measurable snow and impacts. The list below captures the most significant instances with reliable reporting or official measurements.

Why Snow Is Uncommon in Miami

Miami’s low elevation, coastal location, and subtropical to tropical climate keep average winter temperatures well above freezing. Snow requires a deep layer of subfreezing air from surface to cloud and moisture that produces ice crystals; these conditions rarely align near sea level in South Florida. Most cold outbreaks lower temperatures into the low 30s°F (0–2°C) at night but not the sustained sub-28°F (−2°C) necessary for snowflakes to reach the ground without melting.

Typical Cold Patterns vs. Snow-Supporting Setups

• Arctic front passages usually raise lows only to the low 30s°F, preventing snow.
• Snow in coastal South Florida typically requires a strong upper-level low moving through with deep cold air entrenched at the surface.
• When snow does occur, it is most often associated with intense cold-air damming and coastal cyclogenesis upstream of the peninsula.

Documented Snow in South Florida History

The 1977 event remains the most significant snow event on record for coastal Miami-Dade County. During that outbreak, snow accumulations reached around 1–2 inches (2.5–5 cm) in southern Miami-Dade before quickly melting. The 1989 and 1981 events produced much lighter material, generally described as snow grains or brief flakes that melted on contact. More recently, during notable cold snaps in 2010 and 2025, forecasters noted the potential for ice pellets and snow grains, but no accumulating snow was officially recorded at Miami International Airport or nearby COOP stations.

How Forecasters Assess Snow Potential Near Miami

Meteorologists evaluate temperature profiles, moisture transport, and surface wind patterns. Key indicators include a freezing level below 8,000 feet, surface temperatures below 32°F (0°C) for several hours, and low-level moisture. Even when surface temperatures are borderline, wet snow can occur if the layer just above ground is marginally below freezing. In Miami, such setups are exceedingly rare and usually confined to the northernmost suburbs, not the urban coast.

Impacts When Snow Does Appear

When snow does fall in Miami, the primary effects are on tropical vegetation, transportation, and outdoor events. Accumulating snow can damage palm fronds, avocado trees, and other cold-sensitive crops. Roads may become briefly slick, and schools sometimes close as a precaution. Because residents are unaccustomed to snow, even minor accumulations can disrupt commutes and outdoor activities more than in regions with regular winter snow.

Comparing Nearby Snow Events

While Miami rarely sees snow, inland counties and higher elevations in South Florida have recorded more frequent light snow. Below is a concise comparison of documented accumulating snow events within roughly 50 miles of downtown Miami.

Takeaways for Residents and Visitors

• Measurable snow in the Miami city area is rare; the last accumulating event was in 1989.
• Subtropical climate and coastal moderation keep temperatures above freezing during most cold snaps.
• When Arctic outbreaks coincide with strong coastal cyclogenesis, brief snow grains may occur, but accumulations are unlikely.
• Future snow events remain possible during extreme cold-air outbreaks, yet ongoing warming trends reduce their probability.
