Honolulu Temperatures Compared World Wide
Honolulu’s average annual maximum temperature is 27°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 Reykjavík, Iceland, the average annual temperature is significantly lower at 9°C, with mild summers and cold winters.

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.
In Honolulu, during the coolest month, February, you will experience 71% humidity, which is considered high. This is accompanied by an average maximum temperature of 25°C. In the warmest month, August, the humidity is 64% combined with an average maximum temperature of 29°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.
Sea vs. Land Temperatures
The influence of nearby oceans or large water bodies significantly affects local temperatures:
- Ocean Influence: Coastal regions tend to have more stable temperatures, as large bodies of water absorb and release heat slowly. This often results in milder winters and cooler summers compared to inland areas.
- Continental Climates: Landmasses well away from large bodies of water tend to show greater extremes in temperature, having hotter summers and colder winters because of the absence of water as a moderating influence.
