As March arrives in Puerto Rico, the weather begins to transition from the warmer winter months to the milder spring season. This transition is marked by a significant diurnal temperature range, where the difference between daytime and overnight temperatures can be substantial in some regions. Understanding these temperature fluctuations is essential for both residents and visitors to plan their daily activities and make the most of the pleasant weather.
Temperature Ranges across Cities and Regions
The temperature ranges in Puerto Rico vary significantly depending on the location and elevation. In general, cities and regions located near the coast tend to have milder temperatures, while inland areas experience a greater diurnal temperature range.
| City/Region | Average Daytime Temperature (°F) | Average Overnight Temperature (°F) |
| — | — | — |
| San Juan (coastal) | 82 | 70 |
| Ponce (coastal) | 80 | 68 |

Impact on Vegetation Growth and Plant Development
The diurnal temperature range in Puerto Rico has a significant impact on vegetation growth and plant development. Many crops grown in the island, such as coffee, tobacco, and sugarcane, are sensitive to temperature fluctuations.
The coffee plant, for example, thrives in temperatures between 64°F and 75°F (18°C and 24°C), with optimal growth occurring when temperatures range from 70°F to 75°F (21°C to 24°C) during the day.

The diurnal temperature range also affects the growth and development of sugarcane, which requires temperatures between 75°F and 90°F (24°C and 32°C) during the day and above 60°F (16°C) at night. Temperature fluctuations can cause stress to the plant, leading to reduced yields and lower sugar content.
