Factors Influencing Mosquito Activity in San Cristobal

Several factors influence mosquito activity in San Cristobal de las Casas. The region's subtropical highland climate, with its moderate temperatures and rainy season, fosters mosquito proliferation. Key influencers include:
  • Rainfall: More rain means more standing water for breeding.
  • Temperature: Warm temperatures accelerate mosquito life cycles.
  • Altitude: At 2,200 meters, mosquito species here adapt uniquely.
Interestingly, the surrounding pine forests also affect humidity levels, which can increase mosquito survival rates. Understanding these elements helps explain why mosquito presence fluctuates throughout the year, impacting both residents and visitors.
