As summer temperatures rise in Prague, public transport can quickly turn from a convenience into a challenge—especially for those sensitive to heat.

But there’s good news: Prague’s public transport company has shared a simple way to identify air-conditioned vehicles, helping commuters stay cool while navigating the city.

The most reliable way to ride in comfort is to board the Škoda 15T4 tram model. These newer trams come with fully functional climate control systems in the passenger cabin. They’re easy to spot thanks to the yellow plastic panels at the front—currently, 127 of these modern trams operate across Prague.

Older Škoda 15T models, on the other hand, typically have air conditioning only in the driver’s cabin. These trams feature a grey and red nose with no yellow inserts. However, there are two exceptions—trams numbered 9243 and 9285—which do have passenger cabin climate control installed as part of a test program.

How to Check in Advance: Use the Live Map

To avoid waiting in the heat, passengers can check the official online map of Prague’s public transport system, which shows the real-time positions of all trams and buses.

By entering the route number into the search field, users can view all vehicles currently running on that line. Clicking on a specific tram or bus icon reveals detailed information—including a snowflake icon, which confirms whether air conditioning is available.

It’s important to understand how the climate control system operates. The system switches on automatically once the outside temperature rises above 22°C. Drivers cannot adjust the settings manually, as the regulation is fully automated.

Here’s how it works:

• At outside temperatures between 22°C and 25°C, the interior cabin temperature is maintained between 20°C and 25°C.
• When temperatures climb above 25°C, the air conditioning cools the cabin to 1–6°C below the outside temperature.
