Did you see these patterns in the data?

Daily cycles:
  • Air temperatures rise shortly after sunrise, reach their peak late afternoon, and then cool down as the sun sets
  • The air above the water does not vary as much as the air over land, because the steady water temperature moderates it
  • On cloudy days, the temperature does not rise as much
  • On clear nights, the temperature falls more
Comparing land and water temperatures:
  • Water temperatures do not vary much during the day
  • Weather systems can change these temperatures dramatically, as a cold or warm air mass spreads over the region
Seasonal cycles:
  • In summer, the water will rise to about 80 degrees F
  • In winter, the water will fall to about 40 degrees F
