Why is Maryland, USA, Hot? Causes and Heat Countermeasures

Detailed Explanation of the Causes of Heat, Countermeasures, and Cool Spots in Maryland, USA

1. Causes of Heat in Maryland

Maryland is located in the mid-Atlantic region of the United States and has diverse climate characteristics. The main causes of heat are as follows:

1. Mix of Humid Continental and Maritime Climates
   The eastern part of the state is close to the Atlantic Ocean and Chesapeake Bay, so it experiences high humidity influenced by the sea. The western part is inland and influenced by a continental climate, which causes temperatures to rise more easily.
2. Warm and Humid Air from the Gulf of Mexico
   In summer, moist air flows in from the south, increasing the muggy heat.
3. Heat Waves
   High-pressure systems can stall, causing extreme heat lasting from several days to over a week.
4. Urban Heat Island Effect
   In cities like Baltimore and Annapolis, buildings and paved surfaces retain heat, making it difficult for temperatures to drop at night.

2. Heat Countermeasures

To stay comfortable during summer in Maryland, consider the following:

• Use of Air Conditioning and Dehumidifiers
  Since humidity is high, using a dehumidifier along with air conditioning increases comfort.
• Sun Protection
  Use hats, sunscreen, and sunglasses to avoid direct sunlight.
• Hydration
  Frequently replenish water and salt to prevent dehydration and heatstroke.
• Adjust Outdoor Activity Times
  Avoid outdoor activities during the hot hours (12 PM to 4 PM), or stay in the shade if outside.
• Shade Indoors
  Use curtains or blinds to block sunlight and prevent indoor temperature rises.

3. Cool Spots

There are several relatively cool places in Maryland:

• Chesapeake Bay Coast
  Although humidity is high, the sea breeze makes it feel cooler than inland areas.
• Western Mountain Areas (Part of the Appalachian Mountains)
  Higher elevations have cool forests and hiking spots even in summer.
• State Parks and Forest Areas
  Shade from trees and riverside locations help avoid direct sunlight and have lower temperatures.
• Green Spaces and Lakes near Baltimore Suburbs
  These natural areas provide relief from urban heat and offer cooler environments.
