San Juan Weather in April

Warm days, passing showers

April feels hot and humid in San Juan, with highs around 29°C and warm nights near 24°C. Rain falls on about half the days, often interrupting plans rather than washing out the whole day. Expect cloud and roughly five hours of sun a day.

You can still enjoy Condado beach, the forts at Old San Juan and shady streets around Plaza de Armas. But don't count on a full day of clear skies by the water. Long walks along the exposed walls of Castillo San Felipe del Morro can feel sticky in the afternoon.

Easter and spring crowds

Semana Santa, the week leading up to Easter, can bring church services and extra visitors to Old San Juan. The exact dates change each year, so check the calendar if you want to see services near San Juan Cathedral.

Families travelling during school breaks may find the old city and Condado busier, with higher hotel prices around Easter. Outside that holiday period, April is often calmer and less expensive than January to March, San Juan's strongest travel season. It's still a popular spring-break stop, so the quiet depends on the week.

A good fit for city days

For couples who like mixing beach time with history, April works well if you're happy to shift plans around showers. May gets wetter and hotter, while March is drier, so April sits between the two.

A practical Old San Juan tip: after rain, the blue cobblestones can be slick, especially on steep streets near the forts. Take the free trolley between the waterfront and the historic district when your feet need a break, then walk the narrow lanes once the stones have dried.
