It is essential to note that the precipitation levels can vary significantly across the islands, and it is not uncommon for some areas to receive more rainfall than others within a given 24-hour period. This is due to the unique geography and topography of each island, which can create microclimates that receive varying amounts of precipitation.
Temperature Fluctuations Across Islands
The temperature fluctuations across the Hawaiian Islands in November can be attributed to the island group’s geographical location and the influence of the sea surface temperature on the surrounding climate. Located near the Tropic of Cancer, the Hawaiian archipelago lies approximately 2,300 miles northwest of the equator, resulting in a tropical climate characterized by moderate temperatures throughout the year.
The sea surface temperature plays a crucial role in influencing the temperature fluctuations across the islands. In November, the sea surface temperature in the Hawaiian Islands is still relatively warm, ranging from 70°F to 80°F (21°C to 27°C) along the Kona coast of the Big Island to 65°F to 75°F (18°C to 24°C) in the northwestern islands. This warm ocean water contributes to a relatively constant temperature across the islands during the fall season, with a slight decrease in temperature from the peak summer temperatures.
Variation in Temperature within a Single Island
While the sea surface temperature has a significant impact on the temperature fluctuations across the islands, geographical features and microclimates also contribute to variation in temperature within a single island. The Hawaiian Islands exhibit a range of microclimates, from tropical rainforests to arid deserts, resulting in varying temperature conditions throughout the islands.
For instance, the Big Island’s Mauna Kea volcano rises over 13,796 feet (4,205 meters) above sea level, creating a unique microclimate at its summit. The summit experiences a dry and cold climate, with average temperatures ranging from 32°F to 55°F (0°C to 13°C) in November. In contrast, the island’s Kona coast receives significantly more rainfall than the eastern side, resulting in a more humid and warm climate.
Island Group Variations
- The Big Island’s Kona coast is generally warmer and sunnier than the eastern side, with temperatures ranging from 70°F to 85°F (21°C to 30°C) in November.
- The island of Oahu’s windward coast experiences a more significant variation in temperature, with temperatures ranging from 62°F to 78°F (17°C to 25°C) in November.
- The island of Maui’s Haleakala National Park is known for its extreme temperature variations, with temperatures ranging from 40°F to 60°F (4°C to 16°C) near the summit in November.
These variations in temperature within a single island are primarily caused by the combination of sea surface temperature, geographical features, and microclimates. Understanding these fluctuations is essential for travelers and residents alike to plan and prepare for the unique weather conditions found throughout the Hawaiian Islands.

Storm systems play a significant role in shaping the weather patterns of Hawaii in November. The islands are susceptible to various types of storm systems, including tropical cyclones, nor’easters, and subtropical storms. These storms can bring heavy precipitation, strong winds, and rough surf, which can impact the islands’ weather patterns.
Tropical Cyclones
Tropical cyclones are a type of storm system that forms over warm ocean waters. They are characterized by strong winds, heavy rainfall, and storm surges. In Hawaii, tropical cyclones are most common in October and November, with the peak season being from mid-September to mid-December. The islands are generally located outside the typical path of tropical cyclones, but it’s not uncommon for them to pass close to or make landfall.
The most significant tropical cyclone to affect Hawaii is Hurricane Iniki, which struck Kauai in 1992. The storm caused widespread damage and flooding, resulting in 6 fatalities and $3 billion in damage.
Subtropical Storms
Subtropical storms are a type of storm system that forms outside the tropics and typically lacks the strong rotation of a tropical cyclone. They can still produce strong winds and heavy rainfall, but they are generally less intense than tropical cyclones. Subtropical storms can impact Hawaii in November, bringing precipitation and rough surf to the islands.
Some of the notable subtropical storms to affect Hawaii in November include the 2007 Subtropical Storm Barry and the 2012 Subtropical Storm Seymour. These storms brought heavy precipitation and strong winds to the islands, causing disruptions to daily life.
Nor’easters
Nor’easters are a type of storm system that forms along the eastern coast of North America. They can impact Hawaii in November, bringing strong winds and rough surf to the islands. Nor’easters are characterized by strong winds, heavy precipitation, and storm surges.
The most significant nor’easter to affect Hawaii is the 2013 Nor’easter, which brought heavy precipitation and strong winds to the islands. The storm caused widespread power outages and disruptions to daily life.
Factors Affecting Precipitation Distribution
Several factors contribute to the precipitation distribution across the islands, including ocean currents and land features. The trade winds, which blow from the northeast, are a significant factor in shaping the precipitation patterns of Hawaii. The trade winds bring moisture from the ocean to the islands, resulting in precipitation along the windward coasts.
The mountainous terrain of Hawaii also plays a significant role in precipitation distribution. The islands’ high mountain peaks force warm, moist air to rise, cool, and condense, resulting in precipitation. This process is often referred to as orographic enhancement.
The ocean currents surrounding Hawaii also play a role in shaping the precipitation patterns. The North Equatorial Current and the South Equatorial Current bring warm, moist air to the islands, resulting in precipitation along the leeward coasts.
The combination of these factors results in a complex precipitation distribution across the islands, with the windward coasts generally receiving more precipitation than the leeward coasts.

Effects of Trade Winds and Kona Winds
The trade winds and Kona winds play a vital role in shaping Hawaii’s climate, making them a crucial aspect of understanding the state’s weather patterns.
The trade winds, which are also known as the northeast trade winds, blow from the northeast and dominate the weather in Hawaii during the summer months. By November, the trade winds start to weaken, but their influence can still be felt throughout the islands. The speed of the trade winds can reach up to 20-25 knots (23-29 mph), with the strongest winds typically occurring in the morning hours. In November, the trade winds blow from the east-northeast at an average speed of 15-20 knots (17-23 mph).
On the other hand, the Kona winds, also known as the trade wind shadows, occur when the trade winds are blocked by the islands, allowing the winds to blow from the south across the leeward slopes. This phenomenon is most pronounced on the Big Island, where the trade wind shadow creates a unique microclimate. The Kona winds are generally weaker than the trade winds, with speeds ranging from 5-15 knots (6-17 mph).
Temperature Fluctuations
The trade winds and Kona winds have a significant impact on temperature fluctuations across the islands. During periods of strong trade winds, temperatures tend to be cooler, especially in the mornings. However, when the trade winds weaken, temperatures can rise significantly, especially in the afternoons.
In contrast, the Kona winds tend to bring warmer temperatures, especially on the Big Island, where they can increase temperatures by 10-15°F (5.6-8.3°C) compared to areas not influenced by the Kona winds.
Precipitation Patterns
The trade winds and Kona winds also influence precipitation patterns across the islands. During periods of strong trade winds, precipitation is generally more widespread and frequent, with a greater chance of heavy rainfall. However, when the trade winds weaken, precipitation patterns can become more patchy and uneven.
In contrast, the Kona winds tend to bring more frequent and intense showers, especially on the Big Island, where they can lead to heavier rainfall and flash flooding.
Wind-Related Hazards
The trade winds and Kona winds can also lead to various wind-related hazards, such as dust storms and strong winds.
During periods of strong trade winds, dust storms can become a significant concern, especially for people with respiratory issues. The strong winds can also lead to power outages and property damage.
In contrast, the Kona winds can lead to strong winds, especially on the Big Island, where they can cause power outages and property damage.
