What July actually feels like
July is Osaka's hot summer in lived terms: hot and humid, festivals. Most days feel cold, dry and often clear, with damper grey stretches arriving in bursts rather than settling in for the whole month Check the full climate tables below for monthly averages and packing cues.
The underestimated variable is clustered wet days. It truncates outdoor evenings and pushes dinner earlier. Build one indoor spare block every day Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Early July often starts near 30°C while the final week trends toward 32°C. That 1° drift is enough to change coat weight mid-trip. Recheck the forecast before packing day seven Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Afternoons reach 31–32°C before an early sunset near the 15-hour daylight limit — plan open-air stops then.
Evenings cool quickly toward 24°C; shift to indoor dining and illuminated streets once the light drops.
