July, the warmest month, averages a high around 88°F (31.1°C) with lows around 70.9°F (21.6°C). January, the coolest month, averages a high around 48.9°F (9.4°C) with lows around 33.4°F (0.8°C) -- a real, if moderate, seasonal contrast rather than a mild-winters-year-round climate.
Year-round rainfall, peaking in late summer
Greenville receives roughly 34 inches of rain per year on average, spread across 165+ rainy days, with August as the wettest month (about 3.82 inches over roughly 18.7 rainy days). Humidity peaks May and July through September, averaging around 79% relative humidity, with January the least humid month at around 74%.
Hurricane season means real, if intermediate, storm exposure
Atlantic hurricane season runs June through November. Greenville sits on the inner Coastal Plain, not directly on the coast -- it does not face the direct landfall wind/storm-surge exposure of a coastal NC town, but as both Hurricane Florence (2018) and, more severely, Hurricane Floyd (1999) demonstrated, it faces real, documented inland flooding risk from tropical rainfall.

A genuine four-season climate, warmer overall than the NC mountains
Greenville's inner Coastal Plain location gives it noticeably warmer winters and more humid summers than this dataset's NC mountain markets, while still carrying a real winter chill (freezing overnight lows in January are normal) that distinguishes it from a true Deep South or Gulf Coast climate.
