May weather forecast
Dominican Republic

May in the Dominican Republic marks the commencement of the wet season and the definitive arrival of warmer temperatures. Average temperatures during this month generally fluctuate between 21°C (69.8°F) and 32°C (89.6°F), showcasing a substantial rise compared to the preceding months. As the wet season unfolds, both the temperature and the humidity levels begin to surge, marking a significant departure from the comfortable conditions of the dry season.

High-altitude regions such as the Cordillera Central range continue to offer relatively cooler conditions, albeit with an upward temperature trend. The increased heat that the lowland areas experience is somewhat tempered in these higher regions.

By May, the northern regions, including Puerto Plata, start to encounter heavier rainfall, significantly more than the mild increase observed in April. The southern and inland regions, like Santo Domingo, also witness an escalation in rainfall. However, the rain is typically restricted to short, intense showers, often occurring in the late afternoon or evening, leaving much of the day dry and sunny.

The warmer weather of May is a clear indication of the approaching summer, with temperatures consistently rising throughout the month. Despite the increased heat and the onset of the wet season, the weather remains largely bearable, offering a balance between the enjoyable warmth of the sun and the refreshing respite brought by the afternoon showers.

Wind speeds during May typically remain under 32.2km/h (20mph), courtesy of the diminishing northeast trade winds. The chances of tropical storms, while still relatively low, start to increase towards the end of May, signaling the onset of the more volatile weather conditions characteristic of the wet season.
