No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to frigid winters. What many people don’t realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. While air temperatures can vary greatly from day to night or winter to summer, the temperature just a few feet below the earth’s surface stays an average 55°–70°F year-round.
