Oahu moved to the less-restrictive Tier 2 of Honolulu Mayor Kirk Caldwell’s four-tier economic recovery plan on Oct. 22. The mayor’s office says that to gauge whether Honolulu will move to a different tier, the city takes a “weekly assessment” of two key COVID-19 numbers each Wednesday. To move to Tier 3 from Tier 2, the 7-day average of new cases must be below 50 on two consecutive Wednesdays. Also, the 7-day average positivity rate must be below 2.5% on those two Wednesdays.

Today’s seven-day average case count for Oahu is 89 and the positivity rate is 3.1%, according to Caldwell.
