About Newport County Weather
A mild coastal climate near the median
Newport County averages 51.9°F annually, placing it just below the national median temperature. The Atlantic Ocean provides a stabilizing influence that prevents the extreme temperature swings found further inland.
Exceeding the Rhode Island temperature average
The county ranks among the state's warmer regions with an average temperature of 51.9°F compared to the 51.2°F state average. It is notably drier than its neighbors, recording 46.3 inches of rain against a state average of 49.1 inches.
Milder winters than the mainland
Newport's winter average of 33.6°F is warmer than Providence County's 30.0°F, thanks to its coastal position. It also sees significantly less snow, averaging 32.0 inches compared to over 50 inches in the north.
Temperate summers and oceanic breezes
Summer temperatures average a comfortable 70.3°F with only 6 days hitting the 90-degree mark. Winters remain relatively mild for the region, with January lows averaging a manageable 31.1°F.
Focus on moisture protection and mild cooling
High-efficiency dehumidifiers help manage the coastal air, though heavy air conditioning is less critical here than in Kent County. Residents should prepare for 32 inches of annual snow, though coastal salt air often accelerates melting.
