Climate and Weather in DE

DE, short for Delaware, is located in the Mid-Atlantic region of the United States. It has a humid subtropical climate, with hot and humid summers and mild winters. The state experiences a variety of weather conditions throughout the year, influenced by its proximity to the Atlantic Ocean and its geography.

Seasonal Temperature and Precipitation

The temperature in DE varies significantly between seasons. Summers are hot and humid, with average high temperatures ranging from 85°F (29°C) in June to 89°F (32°C) in August. However, heatwaves can push temperatures well into the 90s°F (32-37°C). Winters are milder, with average high temperatures ranging from 41°F (5°C) in December to 46°F (8°C) in February. However, cold snaps can bring temperatures below freezing.

Precipitation in DE is evenly distributed throughout the year, with an average of 45 inches (114 cm) of rainfall annually. The wettest months are typically July and August, while the driest months are October and November. Snowfall is relatively low, averaging around 19 inches (48 cm) per year, with the majority occurring between December and February.

Extreme Weather Events

DE is susceptible to various extreme weather events throughout the year. Thunderstorms are common during the summer months, often accompanied by heavy rain, lightning, and strong winds. Tornadoes are rare but can occur, particularly during severe thunderstorms.

Hurricanes and tropical storms can impact DE, especially along the coast. The Atlantic hurricane season, which runs from June to November, poses a potential threat. These storms can bring heavy rainfall, strong winds, storm surge, and coastal flooding.

Winter storms can also affect DE, bringing snow, ice, and freezing rain. These storms can disrupt transportation, cause power outages, and create hazardous conditions on the roads.

Climate Change

Like many other regions around the world, DE is experiencing the effects of climate change. Rising temperatures, increased frequency of extreme weather events, and sea-level rise are some of the key impacts.

According to the Delaware Climate Change Impact Assessment, the average annual temperature in DE has increased by 1.7°F (0.9°C) since the early 20th century. This trend is expected to continue, with projections indicating a further increase of 3.5°F (2°C) by mid-century.

Sea-level rise is a significant concern for DE due to its low-lying coastal areas. The state's average rate of sea-level rise is higher than the global average, with projections indicating a rise of 1.6 feet (0.5 meters) by 2100. This poses risks to coastal communities, infrastructure, and ecosystems.

Conclusion

DE's climate is characterized by hot and humid summers, mild winters, and a moderate amount of precipitation throughout the year. The state experiences a range of weather conditions, including thunderstorms, hurricanes, and winter storms. Climate change is also impacting DE, with rising temperatures and sea-level rise being notable concerns.
