| Type of Weather Pattern | Description |
|---|---|
| Foggy Weather | Lopez Island is known for its foggy mornings, particularly during the summer months. The fog is caused by the cooling of the air overnight, resulting in the formation of dew and fog. This can lead to a phenomenon known as “sea smoke,” where the fog rolls in off the ocean and envelops the island. As the day progresses, the fog typically burns off, revealing a clear blue sky and perfect weather for outdoor activities. |
| Rainy Days | Rainy days are a common occurrence on Lopez Island, particularly during the winter months. The island receives an average of 70 inches of rainfall per year, with the majority of it falling between November and March. While the rain can be heavy at times, it is often accompanied by a gentle, drizzly mist that sets the island ablaze with vibrant greenery. |
