If you're planning outdoor activities in Houston, accept that humidity is the third dimension of every weather reading. I ran Buffalo Bayou Park in May at 7am: 24°C but 90% humidity, like jogging through warm soup. June-September is genuinely oppressive — 34°C with 75% humidity, heat index pushing 40°C. Best outdoor windows: March-April and October-November, 22-26°C with manageable humidity. Hurricane season (August-September) can disrupt everything. Winter is mild but unpredictable — I once did a January bike ride in 25°C, then a February one in 5°C. Always check radar; Gulf storms intensify fast.
