Explain the climate of the Willamette Valley and the influence the Pacific Ocean has on it
WV is one of the coolest and wettest areas in Oregon. The coastal range mountains offer some protection from Pacific cool/wet influences but breaks in it offer direct influence. Summers are still warm and dry, and due to latitude sunshine hours are high. Diurnal range is high due to warm inland air pulling cool Pacific air inland.
Is irrigation allowed in Willamette Valley?
Only if growers dig their own ponds and retain their own water, river water is only permitted for the longest established vineyards.
Most growers are small plot holders, dry farming is prevalent.
