Covington has a **warm-summer Mediterranean climate (Köppen Csb)**, closely related to the ocean-influenced climate common across the Puget Sound region. Winters are generally cool, wet, and cloudy, while summers are usually mild to warm and noticeably drier.
| Climate Factor | Typical Pattern | |---|---| | Summer highs | Usually in the 70s °F (low to mid-20s °C) | | Winter highs | Often in the 40s °F (about 5–10 °C) | | Rainfall | Significant from autumn through spring; drier in July and August | | Snowfall | Usually light and occasional, though stronger winter storms can bring temporary snow and ice | | Humidity | Moderate to high much of the year | | Sunshine | Most abundant in summer; winters are frequently overcast |
Spring and early summer are popular times for outdoor recreation because landscapes are green and temperatures are comfortable. Late summer is often the driest and sunniest period. Autumn tends to be cool and wet, and winter brings rain, occasional windstorms, and periodic freezing conditions.
Natural hazards are similar to those of the broader Puget Sound area: - Winter windstorms - Heavy rain and localized flooding in poorly drained areas - Snow and ice events that can disrupt travel - Regional wildfire smoke during some late-summer seasons - Earthquake risk, as throughout western Washington
For many visitors, **late June through early September** offers the most consistently pleasant weather.
