Osaka Temperatures Compared World Wide
Osaka’s average annual maximum temperature is 22°C. Let’s compare this with some popular tourist destinations:
Seville, Spain, stands out with its warm Mediterranean climate and an average annual temperature of 23°C.
In contrast, in Oslo, Norway, the average annual temperature is significantly lower at 10°C, with mild summers and cold winters.
Beijing, China, experiences more extreme temperature shifts, but still averaging 20°C annually.
Perth, Australia, experiences a Mediterranean climate, with a pleasant average temperature of 25°C.
How does the temperature feel?
Humidity is an essential factor in how you experience temperature. When a warm period is accompanied by high humidity, it results in a higher perceived temperature. This is especially true when temperatures exceed 25°C, as it can cause greater discomfort.
On the other hand, in cooler months, especially when temperatures dip below 10°C, high humidity can intensify the cold. This makes the air feel much colder than it really is.
In Osaka, during the coolest month, January, you will experience 61% humidity, which is considered high. This is accompanied by an average maximum temperature of 10°C. In the warmest month, August, the humidity is 66% combined with an average maximum temperature of 34°C, which creates a high-feel temperature.

How are these Temperatures Measured?
Generally, temperature data depicting climate is usually given over a 30-year average in order to reduce short-term fluctuations and reveal better long-term trends in climate conditions.
This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.
Effects of Temperature on Weather and Climate
Temperature variations influence precipitation patterns in Amsterdam:
Rainfall: Warm air holds more moisture, leading to heavier rain during warmer months. However, precipitation is generally moderate year-round.
Snow: Occasional snowfall occurs in winter, though it rarely lasts very long.
