San Juan Airport AC Is Still Out at Two Terminals: How to Plan Around It

Is the air conditioning back on at San Juan airport?

No, and no end date has been published. El Nuevo Dia reports that voltage fluctuations have left two terminals at Luis Muñoz Marín International Airport (SJU) without air since August, and that operator Aerostar Airport Holdings is renting mobile cooling units at close to 100,000 USD a month while the damaged equipment is repaired.

The report does not name which two terminals, so do not assume your airline is in the clear. Check your departure terminal in your airline's app the day before you fly and treat the building as a warm space rather than a cooled one.

How do you make a warm terminal bearable?

Dress for the building, not for the plane. A short-sleeve shirt plus a light layer in your carry-on beats a jacket you cannot take off while standing in a bag-drop line. Bring an empty refillable bottle through security and fill it at a fountain after the checkpoint. A 500 ml bottle from an airport concession runs roughly 4-5 USD, against about 1-2 USD at a supermarket in Isla Verde or Condado.

If you check a bag, do the bag drop as early as the counter allows and clear security before the midday crush. Two hours before departure is a reasonable target for a domestic flight out of SJU, and add 30 minutes on a Friday or Sunday. On a long layover, move to an air-conditioned restaurant or lounge rather than sitting at the gate.

What does the rainy Friday forecast change?

Primera Hora is forecasting a wet Friday across Puerto Rico, with rain starting early and continuing into the afternoon as daytime heating feeds new showers, plus a risk of flooding. That changes two things for a traveler.

First, ground transport slows down. A taxi or rideshare from SJU to Condado that usually takes 15-20 minutes can stretch well beyond that when roads hold water, and the same applies to the route into Old San Juan. Second, rental cars and standing water do not mix. Do not drive through a flooded stretch to save 10 minutes. If you are heading toward El Yunque or the east coast on Friday or Saturday, check road conditions before you set out rather than after, and watch your airline app for delay notices if you land or leave during the afternoon storm window.

Where do you go on a wet Saturday in San Juan?

The Puerto Rico Symphony Orchestra premieres "Contrastes Caribeños," a concerto by 24-year-old composer Ema Quiñones, at Bellas Artes on Saturday, according to the San Juan Daily Star. Soloist Andrés Maldonado takes the clarinet and the orchestra has a Spanish-American guest conductor on the podium. It is an indoor, seated concert, which is what a rain-soaked Saturday needs.

Centro de Bellas Artes sits in Santurce, a 10-15 minute taxi ride from Condado when traffic moves, longer in heavy rain. Book through the orchestra's official site rather than a resale page, and keep the ticket on your phone in case the printed copy dies in the weather. If classical is not your thing, the standard rainy-day fallback in San Juan is a museum afternoon in Old San Juan, where the walks between stops stay short.

What should you check before leaving for SJU?

Three things, in this order. Your airline app for terminal and gate, the radar for the afternoon storm window, and your ground transport.

If you are staying in Isla Verde, the ride to SJU is often under 15 minutes, so you can leave later than you would from Old San Juan. From Condado, allow 20-30 minutes with rain traffic. From further out, add more and do not rely on a rideshare appearing in three minutes during a downpour. Screenshot your boarding pass and keep a charged power bank in your carry-on, since a hot wait with a dead phone is the worst version of this trip.

One clarification that matters. El Nuevo Dia's report describes an equipment and comfort problem inside the terminals. It does not mention flight cancellations tied to the air conditioning, so do not rebook anything over this. Plan for a warm building, a wet road and a slower taxi, and the rest of the trip is unchanged.
