Himawari‐8 is a new geostationary meteorological satellite operated by the Japan Meteorological Agency (JMA). The Earth Observation Research Center of the Japan Aerospace Exploration Agency in collaboration with the JMA produces skin sea surface temperatures (SSTs) from Himawari‐8 data. A new quasi‐physical algorithm was used to calculate SSTs. Cloud screening based on the Bayesian inference method was used to detect cloudy pixels. Himawari‐8 SSTs from June to September 2015 were compared with drifting and tropical moored buoy data. This comparison showed a root‐mean‐square difference of ∼0.59 K and a bias of ∼−0.16 K against the buoy data. Positive and variable biases were found in seas along the viewing boundaries.
