Why Coasts Are Warmer
Many people are surprised when they look closely at North America's climate patterns. It can be warmer on the coast of Washington state — or even in parts of Alaska — than it is much farther south! Here's why:

The Wonders of Water
Winter and spring temperatures tend to be warmer along the coasts than they are inland at the same latitudes. This is because water holds heat longer than land does. Because average winter temperatures near oceans are warmer, spring events occur earlier in those areas.

  • Think! Does this mean that spring moves north FIRST along the COASTS? Keep your eyes on Journey North maps in the weeks ahead!

So why does the West coast have warmer winter temperatures, on average, than the East coast does? Read on . . .

Wind and Temperatures
Our Pacific Coast usually has warmer temperatures because most winds come from the west over mild Pacific waters. But winds heading toward the East coast come across colder inland regions.

Think and Journal!
What do Rufous hummingbirds need to survive? How might warmer temperatures influence their ability to meet their needs? (Hint: Think about how temperatures affect hummingbird food sources!)
