Have you noticed more bee activity lately? You aren't alone and it isn't necessarily an odd occurrence. We have had warm temperatures, after all, and wonderful sunny days.
Honeybees can forage year round if the temperatures and weather is nice enough for them. Consider how much rain we've received. Wildflowers and other plants are confused and starting to bloom in odd spots, which gets the bees excited. Even if you don't have anything blooming, the bees may be more active around your home searching for anything sweet from trashcans, pet food, or standing water.
Even if bees have enough honey stored up for the winter, if the day is nice enough to forage, they'll take off! They also use water to help maintain the temperatures in their hive, so finding bees around standing water isn't unusual this time of year, either.
Honeybees are most aggressive when they are protecting their home, so as long as you avoid the home, they'll probably leave you alone. If they do bother you, consider putting some sugar water far away from where you'll be spending time to draw them away.
