Preparing for heatwaves: Residents can cool down at community centres, some indoor sports halls

Key Concepts

• Heat wave definition in Singapore (temperature thresholds and duration)
• Mercury task force and its role in mitigating heat wave impacts
• Public health advisories and cool spots
• Vulnerable populations (elderly, young children) and specific measures for them
• Preventive measures in schools, eldercare facilities, hospitals, and workplaces
• Heat stress sensor network expansion
• La Niña conditions and their impact on temperature
• Long-term trend of hotter days and nights

Measures to Combat Extreme Heat

• Community Centers and Indoor Sports Halls: Residents can seek refuge in air-conditioned community centers and indoor sports halls to cool down during heat waves.
• Mercury Task Force Activation: When the highest daily temperature is expected to exceed 35 degrees Celsius for three consecutive days, and the daily mean temperature reaches at least 29 degrees Celsius, the Mercury task force will implement additional measures.
• Health Advisories: The public will receive health advisories on establishing cool spots at home and minimizing heat injuries.
• Designated Cool Spots: Public spaces, including selected Residents' Committees, will serve as designated cool spots. These spaces will provide opportunities for hydration and cooling down to prevent heat exhaustion.
• Targeted Support for Vulnerable Groups: Special attention will be given to vulnerable populations such as the elderly and young children.

Specific Actions in Different Sectors

• Schools and Eldercare Facilities:
  • Students are allowed to wear attire that is more comfortable in the heat.
  • Residents are closely monitored for signs of dehydration.
  • Outdoor activities are minimized or stopped between 11:00 AM and 4:00 PM.
• Public Hospitals and Outdoor Sports Facilities: These facilities will enhance measures to prevent heat-related injuries.
• Employers: Employers of outdoor workers are required to step up measures to prevent heat-related injuries among their employees.

Expert Perspective

• An expert emphasizes the importance of these plans, especially as hotter days and nights are becoming the "new normal."
• The expert suggests a comprehensive approach, similar to a proposal by O.G. Mathur, to ensure information dissemination across all sectors, enhancing public awareness and preparedness for heat extremes.

Weather Prediction and Monitoring

• Heat Stress Sensor Network Expansion: Singapore will expand its heat stress sensor network by adding eight additional stations island-wide by mid-2025. These stations will measure air temperature, humidity, and wind speeds.

Current Weather Conditions

• La Niña Conditions: Singapore is currently experiencing La Niña conditions, which are expected to bring cooler and wetter weather to the country and the region.
• Temperature Outlook: Despite La Niña, above-normal temperatures are expected from March to May, with May anticipated to be the hottest month.

Historical Context

• Singapore has experienced six heat waves, with the most recent one occurring in 2016.

Synthesis/Conclusion

Singapore is proactively addressing the increasing threat of heat waves through a multi-faceted approach. This includes public health advisories, designated cool spots, targeted measures for vulnerable populations, and enhanced monitoring through an expanded heat stress sensor network. While La Niña conditions may provide temporary relief, the long-term trend of rising temperatures necessitates continued vigilance and preparedness. The Mercury task force plays a crucial role in coordinating these efforts and ensuring the public's safety during extreme heat events.
