The Northwest starts early

Here, the wave rising from south to north breaks: despite the latitude, morels begin to bloom in April, as in Ohio or Pennsylvania, because spring arrives earlier in the ocean. This is why the northernmost band, on average, seems to start earlier.

Because every year is different

  • The season opens with rain: after a heavy rain, with the soil still warm, it takes one or two weeks.
  • In mountain It begins earlier and ends earlier than on the plain, and the same is true for the northern slopes.
  • A'dry summer It pushes it forward, sometimes by weeks. A mild autumn lengthens it.
