During the Pacific 'Blob' event, sea-surface temperatures in some locations were more than 10°F above average.
Notes on verification
Multiple independent sources (NPS, IFLScience) confirm anomalies up to 10°F in some locations, though most retrospectives (NOAA, NASA) cite slightly lower typical peaks of 5-7°F, putting the 'more than 10°F' phrasing at the upper edge of documented figures.
