How is the Weather in Miami During May?

View Cities

May is a transition month as Miami enters the summer rainy season.  Temperatures are very warm, and the afternoons are increasingly humid so expect 13-14 muggy days. 


Temperature

Daytime high temperatures tend to be around 83-85 F (about 29 C) early in May, warming to 86-88 F (30-31 C) near the end of the month. 

About 4-6 of the warmer afternoons can reach or exceed 90 F (32 C).  The record high temperature for Miami during May is 96 F (35.6 F).

Late night and early morning low temperatures tend to be near 70 F (21 C) early in the month, warming to 74-76 F (23-24 C) near the end of the month. 

A few of the cooler mornings, especially early in the month, can dip down near 65 F (18 C).  The record low temperature for Miami during May is 55 F (12.8 C). 


Rain or Shine

About 17 days this month will see sunny, or at least partly sunny skies, however, most of these days will occur during the first half of the month as cloudiness and the risk for rain increase significantly with the onset of the rainy season. 

Overall, about 11 days will record rainfalls of at least 0.01 inches (0.25 mm) with about 4-6 of these recording 0.5 inches (12.7 mm) or more.  The risk for rain late near the end of May is double the risk during the first week of May.


Daylight

The number of daylight hours increases from about 13.1 hours on May 1st to 13.6 hours on the 31st.


Windspeed

Wind speeds will mostly be gentle at 8-12 mph (12-19 kph) to occasionally moderate at 13-18 mph (20-28 kph). 


Ocean Temperatures

If you are headed to the beaches expect warm ocean temperatures around 79-82 F (26-28 C).


What to Wear in Miami during May?

May is very warm and increasingly humid so dress light and airy for summer.  Bring your beachwear including a pair of casual flip flops, sunglasses, sunscreen, and a good pair of walking shoes.

May is the start of the rainy season, so definitely pack an umbrella as well.

Some might actually find the weather a bit too warm, and if that's the case, we recommend a cruise instead!

This is also usually a pretty good time for sporting events, as the Marlins should be entering their second full month of the season in May. Alternatively, there are also plenty of great concerts scheduled for this month.
