Tropical climates bring heat, humidity, and sudden downpours, all of which place extra strain on buses. Passenger safety, comfort, and uptime depend on understanding these challenges and acting early.
· Engines: Cooling systems work harder in hot conditions, increasing the chance of overheating.
· Batteries: High heat accelerates wear, reducing lifespan.
· Tyres: Rising temperatures push up air pressure, raising the risk of blowouts.
· Air-conditioning: Humidity makes AC units work harder, often leading to faster wear and higher fuel use.
· Rain and flooding: Waterlogged routes delay schedules, while prolonged exposure leads to underbody rust and corrosion.
What to Do
· Flush radiators, clean fans, and check coolant often.
· Inspect and replace ageing batteries before failure.
· Monitor tyre pressure in hot spells and fit tyres suited for tropical conditions.
· Check air-conditioning units for blockages and leaks.
· Apply anti-rust treatments, wash undercarriages frequently, and reseal doors and windows to keep water out.
· In downpours, slow down, increase braking distance, and prioritise passenger safety if flooding occurs.
