Forecast, conditions and alerts: National Weather Service. Climate: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Temperatures and rainfall come from NOAA’s gridded normals for Tustin itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Santa Ana Fire Stn, CA (3 mi). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
