Maximum temperatures steadily peak at 29°C (85°F) from June through November, suggesting a subtle increase during the mid-year months. Overall, the atoll maintains a tropical warmth characterized by high humidity and stable seasonal patterns, indicative of its equatorial climate.
Enewetak experiences a mild climate, with temperatures ranging from a minimum of 24°C (76°F) in April to a maximum of 29°C (85°F) in November, offering a warm environment throughout much of the year. For more detailed monthly temperature information, visit monthly temperatures in Enewetak.
Enewetak Atoll's precipitation pattern reveals a distinct seasonal variation, with the wettest months occurring during mid to late summer. January begins the year with relatively low rainfall averaging 50 mm (2.0 in), while February sees a modest decrease to 30 mm (1.2 in). However, rainfall gradually increases from March onward, peaking sharply in August with an impressive 225 mm (8.9 in). This trend underscores a pronounced rainy season that is characterized by both increased precipitation and frequency of rainy days, especially during the summer months.
The frequency of rain also corresponds closely with the volume, as evidenced by the escalating number of rainy days from January to October. January to March experiences 12 to 15 rainy days, but this number jumps significantly to 25 to 29 days during the peak months of July through October. October stands out with the highest recorded precipitation at 298 mm (11.7 in), reinforcing the significance of this period for freshwater collection and ecosystem replenishment. Conversely, December experiences a reduction with 95 mm (3.7 in), signaling a gradual shift towards the drier months. Overall, Enewetak Atoll's precipitation dynamics are crucial to the region's tropical ecology.
Enewetak Atoll experiences a clear seasonal pattern in sunshine duration, with a significant increase in sunlight as the year progresses from winter to summer. Beginning with 238 hours in January, the amount of sunshine gradually rises each month, reaching a notable peak in July at 318 hours. This trend showcases the atoll's transition into a sunnier climate, with the months of March through July consistently offering over 300 hours of sunshine, indicating optimal conditions for outdoor activities and ecological processes.
As autumn approaches, sunlight starts to decline, yet it remains relatively abundant compared to the winter months. For instance, September sees 284 hours of sunshine, followed by October with 286 hours. Notably, November drops to 274 hours, a shift that signals the onset of a less sunlit period as the year closes. Overall, while Enewetak Atoll basks in plentiful sunshine for the majority of the year, the summer months stand out distinctly, making them pivotal for both the health of local ecosystems and the enjoyment of residents and visitors alike.
Enewetak Atoll is characterized by an extremely high UV Index throughout the year, reflecting the atoll's equatorial location. From January to November, the UV Index consistently hovers around 12 to 15, categorizing it as extreme, with a rapid burn time of just 10 minutes for unprotected skin. The highest UV exposure occurs in March with an index of 15, closely followed by April and May at 14. This enduring intensity poses significant risks for skin damage, emphasizing the need for stringent sun protection measures during outdoor activities.
As the year concludes, there is a slight decrease in the UV Index, particularly in December, which registers a UV level of 10 and transitions to the very high exposure category with a burn time of 15 minutes. However, even this reduction indicates that caution is still essential. Overall, the extreme UV conditions throughout most of the year in Enewetak Atoll highlight the importance of protecting oneself from harmful solar radiation, making sun safety practices critical for both residents and visitors alike.

Enewetak Atoll enjoys a relatively stable pattern of daylight duration throughout the year, reflecting its equatorial positioning. The year begins with approximately 11 hours of daylight in January and February, but as March approaches, daylight increases to 12 hours. This extended duration continues through the summer months, maintaining a consistent 12-hour day between March and September, which enhances opportunities for outdoor activities, recreation, and ecological processes on the atoll.
As the year transitions to autumn, daylight hours decrease once again, returning to 11 hours in October and persisting through December. This cyclical pattern highlights the unique balance of light exposure experienced in Enewetak, where months of roughly equal daylight create an environment conducive to both terrestrial and marine life. The consistent daylight duration plays a significant role in the island's climate stability, agricultural practices, and overall quality of life for its inhabitants.
Enewetak, Marshall Islands, experiences a tropical climate characterized by warm temperatures and significant rainfall throughout the year. Monthly averages range from 27°C (81°F) in January to 28°C (82°F) in July, with maximum temperatures reaching up to 29°C (85°F) during the peak months. Precipitation is highest from May to October, particularly in August, which receives about 225 mm (8.9 in) of rain. Sunshine hours peak in July, providing over 318 hours of sunlight, while the annual rainfall totals approximately 1,679 mm (66.3 in). For more information, visit Enewetak climate.
In conclusion, Enewetak Atoll's climate, characterized by warm temperatures, substantial precipitation, and high UV Index levels, coupled with consistent daylight duration, forms a unique ecological environment.
