Heat Wave Safety Tips

Earlier this week, Hilton Head Island was under an excessive heat warning. An excessive heat warning and a heat advisory are crucial alerts issued by the National Weather Service (NWS) to inform the public about dangerously high temperatures. It’s important to understand these alerts and take proper precautions.

  • A heat advisory is issued when the heat index—the combination of temperature and humidity—makes it feel like it is between 100°F and 105°F for two or more consecutive hours. This advisory serves as a warning that the heat could pose a risk, especially for vulnerable populations such as children, the elderly, and those with preexisting health conditions. During a heat advisory, it is essential to take precautions such as staying hydrated, avoiding strenuous activities during peak heat hours, and seeking shade or air-conditioned environments.
  • An excessive heat warning, on the other hand, is more severe. It is issued when the heat index is expected to reach or exceed 105°F for at least two hours. Under these conditions, the risk of heat-related illnesses like heat exhaustion or heat stroke significantly increases. An excessive heat warning calls for heightened awareness and immediate action to protect oneself and others from the extreme temperatures.

Here are some key tips to help you stay safe and prepared for the heat on Hilton Head Island this summer:

  • Stay Hydrated: Drink plenty of water throughout the day, even if you do not feel thirsty. Avoid beverages that can dehydrate you, such as alcohol and caffeinated drinks.
  • Dress Appropriately: Wear lightweight, loose-fitting clothing in light colors to reflect the sun’s rays. A wide-brimmed hat and sunglasses can also provide additional protection.
  • Limit Outdoor Activities: Try to schedule strenuous activities for the cooler parts of the day, such as early morning or late evening. When outdoors, take frequent breaks in the shade or an air-conditioned place.
  • Use Sunscreen: Apply a broad-spectrum sunscreen with an SPF of at least 30. Reapply every two hours, or more often if you are swimming or sweating.
  • Stay Informed: Keep an eye on local weather forecasts and heat advisories. Download weather apps or sign up for alerts to receive real-time updates.
  • Check on Vulnerable Individuals: Regularly check on family members, friends, and neighbors who are more susceptible to heat-related illnesses.
  • Know the Signs of Heat-Related Illnesses: Be aware of the symptoms of heat exhaustion (heavy sweating, weakness, dizziness, nausea) and heat stroke (high body temperature, confusion, loss of consciousness). If someone shows signs of heat stroke, seek medical attention immediately.
  • NEVER leave a baby, senior or pet locked in a car, even for a few minutes.
