Honolulu, Hawaii, has experienced a string of record-breaking high temperatures since mid-May, including a tie of its all-time June high temperature earlier this month.
Monday marked the six-consecutive day Honolulu broke or tied a daily record high in records which date to 1890. Daily record highs have been set on 9 of the first 17 days in June, including a tie of the monthly record of 92 degrees on June 10.
Five additional daily record highs were tied or broken in the second half of May.
Warmer-than-average sea-surface temperatures in the central Pacific Ocean are one factor in Hawaii's record-breaking temperatures since mid-May, according to the National Weather Service (NWS).
Honolulu hasn't been the only city in the island chain to see record-breaking temperatures. Lihue on Kauai and Kahului on Maui have also broken several high temperature records since mid-May.
Kahului tied or set new daily records on 20 of 23 days from May 18 through June 9. This includes new all-time monthly record highs for May (96 degrees on May 22) and June (95 degrees on June 6-7). Weather records in Kahului date back to 1954.
