What is the hottest day ever recorded in Miami?

Miami's hottest day on record reached 98°F, set on August 6, 1954. That is the single most extreme high in the nearest long-term weather station's full daily record — about 14°F hotter than a typical year's average high of 84°F, which is why a day like it stands out as genuinely rare rather than just a hot afternoon.

What is the record high temperature in Miami?

The all-time record high in Miami is 98°F, recorded on August 6, 1954. Records are drawn from the nearest long-term weather station's full daily history, so this is the hottest single day the station has ever logged — not a typical summer peak.

What is the coldest day ever recorded in Miami?

Miami's coldest day on record bottomed out at 30°F, set on January 22, 1985. Like the record high, it comes from the station's complete daily record, so it captures the most extreme cold the area has recorded rather than an average winter low.

What is the record low temperature in Miami?

The all-time record low in Miami is 30°F, recorded on January 22, 1985. The gap between that and the 98°F record high — a span of 68°F — is the full range of temperatures Miami has experienced across its long-term daily record.

Is it normal to be this hot in Miami?

It depends on how far above Miami's normal a given day runs. A typical year here averages a daily high near 84°F; the all-time record of 98°F (set 1954) sits about 14°F above that. The anomaly readout at the top of this page compares the current temperature against this month's normal high, so you can see exactly how unusual today is rather than guessing.

When did Miami set its temperature records?

Miami's record high of 98°F was set in 1954 (August 6, 1954), and its record low of 30°F in 1985 (January 22, 1985). Both are pulled from the station's complete daily record going back to 1948, so they reflect the true extremes rather than a recent or partial sample.

Has Miami been getting hotter?

Yes — Miami's annual mean temperature has trended about 3.2°F warmer since 1948, in line with the long-term warming seen across nearly every US city. That gradual shift in the average is separate from the all-time records above, which mark the single most extreme days rather than the trend, but a warming baseline is part of why recent years more often brush up against the record-high end.

How extreme Miami’s weather gets

Miami’s weather is usually mild by its own standards — a typical year averages a daily high near 84°F, and the normal high for June runs about 89°F. The records sit well outside that everyday range. The hottest day on record reached 98°F in 1954 — roughly 14°F above a typical year’s average high, the kind of gap that turns an ordinary summer into a genuine heat event.

At the other end, Miami has bottomed out at 30°F (1985). Together the two extremes span 68°F — the full width of what this place’s weather has done across the station’s daily record back to 1948. Those edges are exactly why the anomaly readout at the top of this page is worth a glance: it shows where today falls between the normal and the record, so a hot afternoon can be judged against the real history rather than a hunch. A reading a few degrees over the June normal is ordinary; one pushing toward the 98°F record is the rare event the record marks.
