When the weather turns in San Juan
Hurricane season spans June to November; the rest of the year rain means a hard twenty-minute shower rather than a lost day. For a properly wet one, the Museo de Arte de Puerto Rico, the Ballajá barracks museums and the Casa Bacardí distillery tour across the bay in Cataño are all under roof. Old San Juan's balconied streets keep one side of every block dry.
San Juan's museums, and which one to pick
The Museo de Arte de Puerto Rico on Avenida De Diego holds five centuries of island painting, Campeche and Oller included, opening Wednesday to Sunday, dark Monday and Tuesday, running until eight on Thursdays, with a sculpture garden that is free daily. Museo de las Américas fills the Ballajá barracks beside El Morro. The contemporary art museum occupies a Georgian-revival former school in Santurce.
What to eat in San Juan
Mofongo, green plantain pounded with garlic and crackling in a wooden pilón, is the plate, and the roadside kiosks strung along Piñones do a cheaper and often better version beside alcapurrias of green banana and yautía fried to order. Lechón asado belongs to the Guavate road in Cayey, an hour inland. Calle Loíza in Santurce is where the younger kitchens are. The coffee is grown here.
What first-timers get wrong in San Juan
The Tren Urbano has been fare-free since 2024, but it reaches neither Old San Juan nor the airport, so it solves almost nothing for a visitor. AMA buses cost 75 cents and keep loose schedules. This is US territory: dollars, no passport for Americans, no roaming charges, and tipping at fifteen to twenty per cent expected exactly as it is stateside.
What things cost in San Juan
Ten dollars covers both forts for 24 hours and under-sixteens go free. The art museum charges 17 general and 5 for students and over-sixty-fives. An alcapurria at Piñones costs a dollar or two while a mofongo plate in Old San Juan runs 15 to 22. AMA buses are 75 cents, the Tren Urbano currently nothing, and an airport taxi into the old city is a fixed zone fare in the twenties.
