Pendleton climate
Hot humid summers and a long shoulder season shape the best retirement months
NASA POWER data for 2019 through 2023 places Pendleton's average June through August daily high near 91 degrees Fahrenheit and its December through February average daily low near 37 degrees. The series records about 68 days above 90 degrees, about 40 days with lows below freezing, average relative humidity near 76%, and about 1,674 peak sun hours. Five months meet the published comfort window, with April through June and September through October as the best months and July, January, and August as the hardest.
Spring and fall can make the historic center, parks, gardens, and Clemson area outings inviting, while summer requires an earlier schedule, shade, cooling, and indoor alternatives. Inspect air conditioning, attic ventilation, windows, roof, gutters, drainage, mold prevention, trees, storm protection, and backup power. Visit in July or August, not only during a mild spring weekend.

Pendleton in everyday life
Could Pendleton work for you?
What may work well
- April through June and September through October provide the strongest combination of outdoor comfort and local events.
- The town, Clemson area, botanical garden, and parks offer indoor and outdoor choices across the year.
- The climate data makes hot summer days and freezing nights visible rather than hiding them behind a generic warm label.
What to think about
- The city averages about 68 days above 90 degrees in the NASA series.
- Humidity, storms, heavy rain, and air conditioning can affect comfort and utility costs.
- Freezing nights, outages, and wet roads still matter for the home and medical route.
Try Pendleton through heat, rain, and the comfortable months
Visit in summer
Walk the square, run errands, check cooling, review utility bills, and see whether shade, water, benches, and indoor alternatives make the day manageable.
Visit in a wet or cold spell
Inspect roof, windows, gutters, drainage, pipes, trees, driveway, mold prevention, and the route to care after rain.
Practice the storm plan
Confirm alerts, shelter, backup power, food, medication, road information, and a comfortable indoor plan for a multi day outage.
