Dublin to São Paulo (DUB–GRU) — Airlines, Schedules & Connections

Dublin Bus route 747 (Airlink) runs from the city centre (O'Connell Street) to the airport in 30–50 minutes, costing €7 one-way or €12 return. DART rail does not serve the airport directly; the nearest station requires a bus connection. Ride-shares from the city centre typically cost €20–35 depending on traffic.

The M50 and M1 motorways feed into the airport; short-term parking in Terminal 1 or 2 costs from €4/30 min, while long-stay lots (P3/P4) are significantly cheaper for multi-day trips. Allow extra time during morning and evening rush hours on the M50.

CPTM Line 13-Jade to Luz station (central São Paulo) takes 33 minutes (R$4.40). Transfers at Luz connect to metro Lines 1, 3, and 4 for broader coverage. Airport trains run every 30 minutes; check the last departure time if arriving late. Executive buses to Tietê terminal and Paulista run frequently (R$52–62, 45–75 min).Taxis use a fixed airport tariff (zona aeroportuária); central São Paulo costs R$120–200. Uber and 99 are widely used and typically cheaper. São Paulo's traffic is notoriously heavy on the Dutra; road times can double during peak hours. GRU has two terminal buildings (T1/T2/T3 domestic and T3 international); confirm your terminal before heading to check-in.

Humid subtropical climate at 750m altitude. São Paulo is perched on a plateau, which moderates temperatures compared to coastal Brazil. Summers (December–March) are warm and extremely wet. Heavy thunderstorms develop almost daily in the afternoon, regularly causing ground holds at GRU. Flooding in the city can cut road access to the airport even when the runway is clear.

Winters (June–August) are mild and dry (10–20°C) with low humidity. This is the most flight-stable season. Fog occurs occasionally on winter mornings. Temperatures rarely exceed 32°C or drop below 8°C. The rainy season aligns with Southern Hemisphere summer, the opposite of Northern Hemisphere intuition.
