Climate & Weather in Pearland
Pearland shares Houston's humid subtropical climate: hot, humid, long summers and short, mild winters. Sources cited Pearland's mean yearly temperature at about 69.8°F, with August the warmest month (average around 83.4°F) and January the coolest (average around 54.0°F) -- and annual rainfall commonly cited in the 50-55 inch range, though the city's own Hurricane Harvey record (49.2 inches in a single 2017 storm) shows how far a single extreme event can exceed a typical year's total.

Pearland's mean yearly temperature is cited around 69.8°F (21.0°C), with August as the warmest month at an average of about 83.4°F (28.6°C) and January as the coolest at about 54.0°F (12.2°C). One source separately describes typical summer highs around 90°F and winter highs in the 40s-50s°F -- broadly consistent with the mean-temperature figures, and in line with the humid subtropical pattern the whole Houston region shares.
Rainfall: A Wet Climate Year-Round, With Real Extremes
Annual precipitation is commonly cited in the 50-55 inch range, falling mostly in the summer months. That's a typical-year figure -- Hurricane Harvey's 49.2 inches recorded at Mary's Creek in a single multi-day event in August 2017 (see the insurance-hazard-costs topic page) shows how dramatically a single storm can approach or exceed a full year's normal rainfall, underscoring why flood-risk planning matters here beyond routine wet-season expectations.
Hurricane Season in Practical Terms
Atlantic hurricane season runs June 1 through November 30. As covered on the insurance-hazard-costs topic page, Pearland's practical risk during this window is centered on heavy rainfall and Clear Creek/Mary's Creek watershed flooding rather than direct storm-surge exposure, since the city sits inland of the open Gulf -- but that inland position did not prevent real, documented flood damage during Harvey.
Humidity as a Year-Round Factor
Gulf Coast humidity is present across most of the calendar in Pearland, not just the hottest months, moderating somewhat in the comparatively drier winter. This affects daily comfort and air-conditioning costs (see the cost-of-living topic page) and is a genuine adjustment for anyone relocating from a drier climate.
Key takeaways
- Pearland's mean yearly temperature is cited at about 69.8°F, with August the warmest month (~83.4°F average) and January the coolest (~54.0°F average) -- essentially no true cold season.
- Annual precipitation is commonly cited in the 50-55 inch range for a typical year, but Hurricane Harvey alone dropped a state-record 49.2 inches at one Pearland-area gauge in 2017 -- a reminder that single extreme events can rival a full year's normal total.
- Hurricane season (June 1-November 30) is a real planning factor centered on heavy-rain/watershed flooding rather than direct storm surge, given Pearland's inland position -- though that position didn't prevent documented Harvey flood damage.
- Humidity is a year-round factor, not just a summer one -- a genuine adjustment for anyone relocating from a drier climate.
