Hawai‘i Climate Guide: What to Expect During Your Visit to Pearl Harbor

Seasons and Temperatures

Hawai‘i experiences two main seasons:

  • Winter (ho‘oilo in Hawaiian): November to March
  • Summer (kau wela in Hawaiian): April to October

Unlike the mainland U.S., temperatures in Hawai‘i remain fairly consistent throughout the year, with daytime highs ranging from the mid-70s to mid-80s°F. The coldest temperatures during winter rarely dip below 60°F.

Rainy Season

Winter is also the rainy season in Hawai‘i, during which flash floods can occur. Frequent rain showers often give way to stunning rainbows as the skies clear, adding a beautiful touch to the landscape.

Trade Winds

Trade winds are a significant factor in O‘ahu’s climate:

  • Present 90% of the time in summer
  • Occurring 50% of the time in winter

These winds help keep temperatures moderate and reduce humidity levels, making the climate more comfortable year-round.

Boat Ride Suspensions

Please note that boat rides to the USS Arizona Memorial may be suspended due to high winds. This decision is made by the U.S. Navy, which operates the boats. If tours are suspended, they will resume once the wind conditions improve.
