Beyond today’s pollen
What this forecast doesn’t measure, and when to get help.
No mold level
Google’s index covers tree, grass and weed pollen only, so there is no mold level for Miami on this page. The National Allergy Bureau publishes pollen and mold counts measured at its stations. Our guides cover common molds such as Alternaria, Cladosporium and Aspergillus.
No indoor allergens
The forecast doesn’t cover allergens indoors either: dust mites, cockroaches, mice, cats and dogs. Our guides explain each one, starting with dust mites and cats.
Asthma in Miami
An estimated 8.6% of adults in the city of Miami have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 7.6% to 9.6%). It is a statistical estimate from national survey data, not a count.
Allergists in the Miami area
81 allergists enrolled in Medicare practice in the Miami area: 1.27 for every 100,000 people, more than the 1.22 across the US. The count doesn’t show how soon you can get an appointment. See the doctors listed in the Miami area, or how every state and metro compares.

Miami’s pollen seasons
The geography, climate and plants behind each season here, with a source for every fact.
Melaleuca was the most common tree in the urbanized part of Miami-Dade County when researchers sampled it in 2008, at 42% of all trees.2 Red mangrove, button mangrove and Benjamin fig followed.2 A UF/IFAS Extension agent in Broward County names melaleucas, oaks and pines as trees whose lightweight pollen grains travel miles.3 Florida’s pollen season starts in North Florida, then creeps south and peaks in South Florida from February to May.3
A typical year at Miami International Airport has no freeze at all, and about 67 inches of rain and other precipitation falls.1 The National Weather Service dates South Florida’s wet season from May 15 to October 15, the part of the year that brings 60% to 70% of the average yearly rainfall.4
Australian pine is commonly seen along Florida’s coastlines and has naturalized in the state south of Orlando.5 UF/IFAS considers the tree extremely allergenic, and it blooms twice a year in Florida, in April and again in June.5 Among grasses, Bermudagrass pollinates year-round in subtropical parts of the state.6
