Factors Affecting Mosquito Activity in Chelsea

Several factors influence mosquito populations in Chelsea, from weather patterns to urban features. Key influencers include:

Standing water in parks and residential areas, which serve as breeding grounds.
Temperature fluctuations, as mosquitoes are more active above 50°F.
Seasonal rainfall, which increases available habitats.

Chelsea's proximity to the Mystic River and its network of wetlands creates ideal conditions for mosquitoes. Urban heat islands, especially near Chelsea's industrial zones, can also extend mosquito activity later into the season. Understanding these factors helps locals and visitors anticipate mosquito presence and take precautions accordingly.
