Essential Tips

What to Pack

Lightweight breathable rain jacket - October thunderstorms are intense but brief (45-90 minutes), and umbrellas are useless in the wind

SPF 50+ broad spectrum sunscreen - UV index of 8 combined with reflection off wet surfaces after rain increases exposure risk

Quick-dry cotton or linen clothing - avoid polyester which becomes unbearable in 70% humidity, especially during midday heat index of 38-40°C (100-104°F)

Comfortable closed-toe walking shoes with good grip - temple floors and heritage sites become slippery after afternoon downpours

Portable phone charger/power bank - high humidity can affect battery life, and you'll use GPS frequently for navigating monsoon-altered routes

Light scarf or shawl for temple visits - required for shoulder covering, and cotton material helps with air conditioning transitions

Antacid tablets - October street food season coincides with spice-heavy festival preparations that can overwhelm unaccustomed stomachs

Insect repellent with DEET - post-monsoon conditions create ideal breeding environments, especially near water bodies like Pulicat Lake

Waterproof phone case - essential for photography during unexpected downpours and high humidity conditions that can damage electronics

Electrolyte packets - combination of heat, humidity, and frequent indoor/outdoor transitions can cause dehydration faster than expected

Insider Knowledge

Visit major temples before 9am or after 6pm - not just for heat avoidance, but because priests perform special October rituals during these hours that tourists rarely witness

Book train tickets to nearby destinations (Pondicherry, Tirupati) at least 15 days ahead - October begins domestic tourism season and popular routes sell out quickly

Shop for silk sarees and traditional clothing in T. Nagar during 2-4pm when locals avoid the heat - you'll get better attention from shopkeepers and avoid evening festival shopping crowds

Time your Marina Beach visits for 6:30-8:30pm when sea breeze is strongest and locals emerge for evening walks - this is when authentic street food vendors set up their best offerings

Avoid These Mistakes

Planning outdoor activities between 11am-4pm when heat index reaches dangerous levels of 38-40°C (100-104°F) - even locals stay indoors during these hours

Assuming monsoon is completely over - October can still deliver surprise heavy downpours that flood streets within 30 minutes, disrupting all ground transportation

Booking accommodation without air conditioning - October humidity of 70% makes rooms uncomfortable even at night when temperatures only drop to 24°C (76°F)
