Weather Travel Tips

  • Pack lightweight, breathable cotton clothing to stay comfortable in Chennai's heat and humidity.
  • Carry an umbrella or raincoat at all times, especially from October to December when rains are heavy.
  • Stay hydrated by drinking bottled or filtered water, and avoid street food that may be contaminated.
  • Use sunscreen, a hat, and sunglasses to protect against the strong sun, particularly from March to June.
  • Plan outdoor activities for early morning or late evening to avoid the peak heat of the day.
  • Use reliable transportation like app-based cabs or the metro, as auto-rickshaws may overcharge tourists.
  • Dress modestly when visiting temples and religious sites, and remove footwear before entering.
  • Check the weather forecast daily during monsoon months, as sudden downpours can disrupt travel plans.
