March is possibly the best month of the year to visit San Juan, Puerto Rico, for a cruise or stayover vacation.

San Juan’s average weather in March has only two inches of rain and a high temperature of 84 degrees Fahrenheit, according to historical records from the U.S. National Weather Service.

This historical city on Puerto Rico is a common port of call for eastern Caribbean cruises. It also is a common embarkation point for eastern and southern Caribbean cruises.

It is widely known for shopping, dining, architecture and especially the historical site of Old San Juan, which lies near the cruise terminals.

Rain in March


March is an important weather month for San Juan because it is part of a brief dry season that visits the city.

The average rainfall of 2.4 inches is a low point of the year along with the cooler February.

By comparison, rainfall climbs to four inches in April and keeps climbing until it reaches a high point of six inches in October and November.

It rains about eight days on average in March, the National Weather Service says. That’s better than the 13 to 14 days it rains each month from July through December.

Temperatures in March


San Juan’s average high temperatures stay in a fairly tight range throughout the year between the lower and upper 80s Fahrenheit.

In March, the average high temperature is 84 degrees Fahrenheit or 29 Celsius. The average low, which takes place mostly at night, is 72 Fahrenheit or 22 Celsius.

These moderate temperatures are comfortable for land activities throughout the day. But the nighttime temperatures are cool enough that water is chilly at times for swimmers.

Even though there is a beach close to the cruise terminal, cruise visitors is more likely to go to Old San Juan anyway.
