5 Tips For Rainy Season In Bali 2025
Bali’s rainy season, typically running from November to March, is a dynamic period marked by lush greenery, cooler temperatures, and, of course, heavy downpours. While the island’s tropical charm remains ever-present, the wet season brings its own set of health challenges and lifestyle adjustments. Whether you’re a resident, digital nomad, or holidaymaker, being well-prepared can make a significant difference in your comfort and wellbeing.
At Trishnanda Care Centre, Bali’s trusted mobile healthcare clinic, we are committed to keeping you safe and healthy; rain or shine. This expert guide will walk you through five essential tips for staying well during the rainy season in Bali in 2025, backed by the latest international and local medical recommendations.
1. Protect Yourself Against Mosquito-Borne Illnesses
Understanding the Risks
The rainy season in Bali creates ideal breeding conditions for mosquitoes, particularly Aedes aegypti, the vector responsible for dengue fever. According to the World Health Organization (WHO), dengue transmission surges during and just after the rainy season due to increased standing water. Other mosquito-borne illnesses, such as chikungunya and Zika, have also been reported throughout Southeast Asia.
How to Reduce Your Risk
• Use Mosquito Repellent: Apply an EPA-registered repellent containing DEET, picaridin, or oil of lemon eucalyptus. Reapply as instructed, especially after sweating or swimming.
• Wear Protective Clothing: Dress in long-sleeved shirts and long pants when outdoors, particularly at dawn and dusk when mosquitoes are most active.
• Eliminate Standing Water: Regularly empty containers, buckets, plant saucers, and any other items that collect rainwater around your villa or accommodation.
• Install Screens and Mosquito Nets: Ensure your living space is fitted with window and door screens. Use mosquito nets while sleeping if your accommodation is not fully enclosed.
Medical Support for Dengue and Related Illnesses
If you experience high fever, severe headache, pain behind the eyes, joint pain, or a skin rash, seek medical attention promptly. Trishnanda Care Centre offers Dengue IV Therapy for supportive care and symptom relief, along with in-villa lab testing (including dengue NS1 antigen tests). Our 24/7 doctor-on-call service ensures you’re never alone, day or night.
2. Prioritise Immunity and Hydration
Why Immunity Matters More in Wet Weather
Frequent rains and fluctuating temperatures can compromise your immune defences, making you more susceptible to viral and bacterial infections such as influenza, the common cold, or even gastroenteritis. According to research published by the Centers for Disease Control and Prevention (CDC), close indoor contact and humidity can facilitate the spread of respiratory viruses.
Practical Steps to Support Immunity
• Eat a Balanced Diet: Focus on fresh fruits, vegetables, and lean proteins to provide essential vitamins and minerals.
• Stay Hydrated: High humidity may mask dehydration. Drink plenty of filtered water throughout the day.
• Get Enough Sleep: Quality sleep underpins immune health.
• Wash Hands Frequently: Practice regular handwashing to reduce transmission of germs.
Medical Services for Immunity and Hydration
To further strengthen your immune response, consider Trishnanda Care Centre’s Immunity IV Therapy or Hydration IV Package, delivered directly to your villa. These therapies supply essential fluids, electrolytes, vitamin C, and other nutrients that support your body’s natural defenses.

3. Manage Food Safety and Digestive Health
Increased Risk of Foodborne Illnesses
Warm and humid conditions during the rainy season promote rapid bacterial growth in food. This elevates the risk of food poisoning, commonly known in Bali as “Bali Belly.” According to the Food and Agriculture Organization (FAO), improper food handling and storage are leading causes of foodborne outbreaks during wet weather.
How to Protect Your Digestive System
• Choose Reputable Eateries: Opt for restaurants and warungs that are busy and have good hygiene practices.
• Consume Freshly Cooked Foods: Avoid raw or undercooked meats, seafood, and eggs.
• Wash Fruits and Vegetables: Rinse produce with clean, filtered water before consumption.
• Stay Cautious with Street Food: If you indulge, select stalls where food is cooked in front of you and served hot.
Fast Relief for Bali Belly
Should you develop symptoms like stomach cramps, nausea, vomiting, or diarrhea, prompt hydration is crucial. Trishnanda Care Centre provides a comprehensive Bali Belly IV Therapy, as well as specialised options for mothers (Bali Belly Mom Care IV Therapy). These treatments help restore electrolytes and reduce discomfort; available 24/7 via our mobile service.
If you’re uncertain about the cause of your symptoms, our in-villa Doctor-on-Call service can provide a professional diagnosis and recommend the most effective treatment.
4. Prepare For The Unexpected: Accidents and Waterborne Hazards
Slippery Surfaces and Increased Injury Risk
The rainy season brings slick roads and walkways. According to the Bali Provincial Health Office, the incidence of slips, trips, and motorbike accidents rises significantly during heavy rainfall periods.
Staying Safe During Heavy Rains
• Wear Proper Footwear: Shoes with good traction help prevent slips on wet tiles or pavements.
• Be Cautious on Roads: If riding a motorbike or scooter, slow down and avoid flooded areas. Always wear a helmet.
• Avoid Swimming in Flooded Areas: Floodwaters often harbor bacteria, parasites, and debris.
Rapid Medical Response Anywhere
Trishnanda Care Centre offers 24/7 nurse and doctor visits island-wide. In case of minor injuries or sudden illness, our team can reach you quickly for wound care, pain management (Relief IV Therapy), or other emergency support in the comfort of your accommodation.
We also provide Flu IV Therapy for those who may pick up seasonal viruses due to increased indoor crowding during storms.
5. Plan Ahead With Preventative Healthcare
Vaccinations and Routine Health Checks
Wet weather increases the risk of certain infections, including influenza and hepatitis A. The CDC recommends that travelers to tropical destinations ensure they are up-to-date on standard immunisations and consider additional protection against waterborne or mosquito-borne diseases.
What You Can Do
• Book Travel Vaccinations: Prepare ahead by scheduling travel vaccinations before arrival or at the start of the rainy season.
• Schedule Health Screenings: Regular check-ups can detect early signs of infection or underlying conditions worsened by humid conditions.
• Monitor Chronic Conditions: If you live with asthma, diabetes, or heart disease, keep your medications stocked and easily accessible.
