Coastal regions in Hawaii experience a relatively consistent temperature range throughout July, with average highs of around 86°F (30°C) and lows of 70°F (21°C). This is because the ocean has a moderating effect on the climate, keeping temperatures relatively stable. In contrast, the mountainous regions experience a more significant temperature drop as elevation increases. For example, at the summit of Haleakala on the island of Maui, temperatures can range from 50°F (10°C) to 70°F (21°C) during the day, while nighttime temperatures can drop to around 40°F (4°C). This is due to the decreasing humidity and increasing elevation, which allow for a greater temperature gradient.
- Coastal regions experience a more stable temperature range due to the moderating effect of the ocean.
- Mountainous regions experience a greater temperature drop as elevation increases.
- The temperature difference between coastal and mountainous regions can be up to 20°F (11°C) or more.
Relationship between humidity and sunny hours
Hawaii’s tropical climate is characterized by high humidity levels throughout the year. During July, the average relative humidity is around 64%, with some areas experiencing as high as 80% humidity. This high humidity can make the air feel hotter than it actually is, which can affect the perception of the number of sunny hours experienced during the day. In fact, research has shown that when the relative humidity is above 60%, the air can feel up to 10°F (5.5°C) warmer than it actually is. This means that even on days with minimal cloud cover, the high humidity can make the air feel warmer and more oppressive.

Rainfall in Hawaii during July is usually concentrated in specific regions
During the summer months, Hawaii experiences a unique weather pattern characterized by minimal rainfall. However, the islands do not remain completely rain-free throughout the month of July. In fact, rainfall in Hawaii during July is often concentrated in specific regions, influenced by the trade winds and topographical features of the islands.
The Role of Trade Winds in Rainfall Distribution
The trade winds, which originate from the northeast, play a significant role in shaping the climate of Hawaii. In July, these winds bring moisture-laden air to the islands, leading to increased precipitation in certain areas. The trade winds are strengthened by the temperature difference between the equator and the poles, resulting in a more pronounced east-west precipitation gradient. This gradient manifests in the form of increased rainfall on the windward sides of the islands, particularly on the islands of Kauai, Oahu, Maui, and the Big Island.
The Windward Coast of Kauai
Kauai’s windward coast is particularly prone to heavy rainfall during July. The island’s lush vegetation, towering mountain ranges, and rugged coastline create an orographic effect, leading to significant precipitation accumulation. This area is often referred to as the “Garden Isle,” and for good reason – the region’s rainfall is some of the highest in the state, with monthly averages reaching over 10 inches in July.
The Kona Coast of the Big Island
In stark contrast to Kauai’s windward coast, the Kona coast of the Big Island is a dry and sunny region. Located on the leeward side of the island, this area is protected from the trade winds and receives significantly less rainfall. However, when the trade winds do reach the Kona coast, the result can be intense rainfall and flash flooding events. These events are often the result of a phenomenon known as “Kona storms,” which occur when a low-pressure system develops over the Kona coast and brings heavy rain and strong winds.
Average Monthly Rainfall Across the Islands
While rainfall is concentrated in specific regions, other islands experience relatively dry conditions throughout the month of July. Here’s a snapshot of the average monthly rainfall across different islands in Hawaii:
| Island | Average Monthly Rainfall (July) |
| — | — |
| Kauai | 10.31 inches |
| Oahu | 4.31 inches |
| Maui | 3.45 inches |
| Big Island | 2.56 inches |
| Lanai | 1.35 inches |
| Molokai | 2.15 inches |
| Kahoolawe | 1.08 inches |
In summary, rainfall in Hawaii during July is concentrated in specific regions, primarily driven by the trade winds and topographical features of the islands. The windward coast of Kauai and the Kona coast of the Big Island are two regions that stand out for their unique weather patterns. While other islands experience relatively dry conditions, these regional variations highlight the importance of understanding the complex interplay of climate and geography in shaping the weather in Hawaii.
