Graphical Climatology of Miami Temperatures, Rainfall and other Variables (1949-Present)

The following is a graphical climatology of Miami, Florida (International Airport) temperatures, precipitation, and various other parameters, from 1949 into the present year 2024. Presented are daily climatological overview charts (temperature and rainfall), annual time-series (temperature and rainfall), “climograms” (hour-by-month depictions of temperature, humidity, winds, Flying Weather, cloud ceilings, fog, and thunderstorms), followed by year-to-year graphs that depict daily max/min temperature, daily mean temperature anomalies, and daily rainfall. The year-to-year graphs go back to 1949, the annual rainfall series back to 1906.

YEAR-TO-YEAR GRAPHS:

The year-to-year daily graphs pages (links below) consist of four charts tiled horizontally. The uppermost graph displays “floating-bars” or “hi-lo” depictions of the daily maxima and minima. Each bar represents an individual day’s temperature range. Superimposed are two line traces, the upper one connecting average daily maxima, the lower one average daily minima. The bars depict the varying diurnal, synoptic, long-wave, seasonal, and sea-surface temperature influences on temperature over time, and subjectively, some years’ features can be quite interesting to look at (see “REPEAT LINKS TO SOME OF THE MORE INTERESTING YEAR-TO-YEAR GRAPHS, WITH ACCOMPANYING NOTES” section below).

The second chart down shows the arithmetic departures of day-to-day mean temperatures less the corresponding calendar-day average means. Vertical lines extending upward from the zero line indicate above average means for the day (colored red), those extending downward indicate below average daily means (colored blue). In the entire series, the most extreme departure of either sign is -31 F on 24 December 1989 (associated with a daily maximum: 45 F, daily minimum: 31 F)

(Note: Clicking on the floating-bar charts a second time after they appear on the screen will enlarge them even further).

The third chart down shows the second chart’s departures in deseasonalized or “standardized” form. Standardized anomalies are calculated by dividing the arithmetic anomaly by the climatological mean temperature standard deviation for the calendar day in question, creating “z-scores”. Through the present, the most extreme z-score was -4.27 z, for 29 June 1966

The fourth chart down depicts daily rainfall, as high as 14.85 inches (25 April 1979).
