Arcata's barometric pressure is influenced by its proximity to the Pacific Ocean. The pressure changes frequently due to the ocean's moderating effect. This results in a mix of high and low-pressure systems.
The city is situated in a valley near the ocean. This unique landscape creates a channel for marine air to move inland. The surrounding hills and mountains block or redirect winds.
These wind patterns disrupt the airflow, causing pressure changes. As a result, the barometric pressure in Arcata is often unstable. This instability leads to fluctuating weather conditions.
