Singapore Travel Essentials 2025: MRT Tap-and-Go, SG Arrival Card & Weather Hacks

## Planning Your Trip to Singapore in 2025 Singapore is one of the smoothest, safest, and most technologically seamless destinations on earth. However, several post-2024 updates can save you time and unnecessary transit card costs! --- ### 1. You NO LONGER Need to Buy an EZ-Link Card Good news! Singapore MRT trains and public buses accept **SimplyGo contactless payments**: * You can simply tap your existing Visa or Mastercard credit/debit card, Apple Pay, or Google Pay directly at the turnstiles. * Foreign transaction fees are minimal (usually less than S$0.50 per day for transit batches). * No need to queue at Changi Airport ticket counters or worry about unspent card balances. --- ### 2. Mandatory SG Arrival Card (SGAC) with Electronic Health Declaration * All international travelers (including tourists) must submit the free **SG Arrival Card** online within **3 days prior to arrival** in Singapore. * **Official URL:** [eservices.ica.gov.sg](https://eservices.ica.gov.sg) (Do NOT pay third-party scam sites — the official submission is 100% free). * You will receive an instant PDF barcode via email to show border control. --- ### 3. Beating the Humidity: The "Underground Highway" Singapore temperatures hover around 30°C–33°C (86°F–91°F) with 80% humidity year-round. * **Secret Hack:** Much of central Singapore (Orchard Road, City Hall, Marina Bay, Suntec City) is interconnected by fully air-conditioned subterranean shopping malls and underground pedestrian links. * Always carry a light folding umbrella and a refillable water bottle (tap water in Singapore is 100% potable and meets WHO standards).
