This dataset presents projected hourly time-series of wave heights, wave periods, incident wave directions, and directional spreading at distinct points along the U.S. West Coast and surrounding Hawai’i for the years 2020 through 2050. The projections were developed by running the National Oceanic and Atmospheric Administration’s (NOAA’s) WAVEWATCHIII model. Wind and sea-ice fields from seven different Global Climate or General Circulation Models from the CMIP6 High-Resolution Model Intercomparison Project were used to simulate waves across the globe at a 0.5-degree resolution (approximately 50 km, depending on latitude) and further downscaled to 10- (approximately 18 km) and 4-arc-minute (approximately 7 km) model grids. Point model output data extracted from NOAA’s 4 arc-minute grid for the U.S. West Coast and Hawai’i (wc_4m) are provided herein.
