Phoenix, Arizona: It's rattlesnake weather in in Arizona, as residents and visitors are reminded to exercise caution on trails due to increased activity. The Phoenix Herpetological Society told ABC 15 that the state's 13 rattlesnake species are more active during cooler months, increasing the likelihood of encounters during outdoor activities.

Rattlesnakes are ectothermic, meaning they rely on external heat sources to regulate their body temperature. During the extreme heat of summer, they often seek shelter during the day to avoid overheating. When temperatures cool in fall and winter, the weather becomes more comfortable for them to move around and hunt, making them more active.

While rattlesnakes don't hibernate in the traditional sense, they do enter a state called brumation in winter, where their metabolic processes slow down significantly. Before fully entering brumation, however, they become more active to find food and prepare for this dormant period. This pre-brumation activity is often seen in late fall.

When temperatures cool in fall and winter, the weather becomes more comfortable for rattlesnakes to move around and hunt.

For some species of rattlesnakes, the fall season is also part of their mating cycle. Males may roam more extensively in search of females, which contributes to higher activity levels during cooler months.

To ensure safety, follow the following guidelines:

Stay on designated trails: This practice allows for better visibility and reduces the chance of disturbing snakes hidden in underbrush.

Watch your step: Be mindful of where you place your feet, especially when navigating over rocks or logs, as snakes may be concealed beneath

Avoid handling snakes: If you come across a rattlesnake, do not attempt to touch or move it. Most bites occur when individuals try to handle or provoke the snake

In the event of a rattlesnake bite, take the following steps immediately

Call emergency services: Dial 911 without delay, as prompt medical attention is crucial.

Keep calm and still: Minimize movement to slow the spread of venom.

Remove constricting items: Take off jewelry or tight clothing near the bite area to allow for swelling.

Position the bite below the heart: If possible, keep the bitten area lower than heart level to reduce venom circulation

Never attempt to suck out the venom, apply ice, or use a tourniquet, as these methods can cause further harm.
