Port Royal climate and seasons
Warm humid weather makes shade, drainage, cooling, and coastal storm systems part of the home choice
NOAA's 1991 to 2020 normals for Beaufort MCAS report a 67.2-degree annual mean, mean daily high and low of 76.8 and 57.6 degrees, January highs and lows near 60.3 and 40.1 degrees, and July highs and lows near 91.8 and 74.5 degrees. Annual precipitation is 45.02 inches, the station records 73.1 days with highs at least 90 degrees and 16.9 nights at or below freezing, and normal snowfall is zero.
Port Royal's marshes, tidal waterways, humidity, heat, heavy rain, tropical systems, and storm surge make the regional normals only a starting point. The catalog lists a current temperature of 26 degrees Celsius, humidity of 65, AQI of 81, and a warm climate band. Inspect air conditioning, shade, windows, roof, drainage, mold, flood elevation, trees, backup power, wind coverage, and the route to care during heat, smoke, heavy rain, and a storm.

Port Royal in everyday life
Could Port Royal work for you?
What may work well
- Mild winters, a long warm season, marsh, waterfront, and nearby trails support an active calendar.
- Parks, wetlands, boardwalks, museums, and indoor civic options provide alternatives when the coast is hot or wet.
- The regional setting makes it possible to combine Port Royal outdoor life with Beaufort services and larger indoor options.
What to think about
- Hot humid summers and warm nights can make cooling, shade, and electricity essential.
- Heavy rain, tidal flooding, surge, wind, mold, termites, hurricanes, and power interruption can change a season quickly.
- Beaufort MCAS is a regional reference and does not replace a drainage, flood, shade, elevation, or wind review for the exact property.

Plan for July highs near 91.8 degrees, 73 days at or above 90 degrees, 45.02 inches of rain, warm nights, few snow concerns, and tropical-system exposure.
Inspect cooling and drainage
Request equipment age, service history, utility records, shade, windows, roof, foundation, drainage, mold, termites, flood elevation, and backup power.

Plan weather alternatives
Balance outdoor outings with museums, libraries, indoor exercise, maritime programs, home activities, and regional options for heat, smoke, flooding, or evacuation.
