Hanford, California – Triple-digit heat will blanket Hanford and much of the San Joaquin Valley Sunday, pushing thermometers to a blistering 104°F by afternoon. The National Weather Service has issued a Heat Advisory through 8 a.m. Monday, warning residents to limit outdoor activity, hydrate frequently, and avoid prolonged sun exposure, especially along State Route 198, where pavement temperatures could exceed 130°F.
According to the NWS Hanford office, there’s also a slight chance of isolated showers Sunday, particularly in the late afternoon and evening. While rainfall totals are expected to remain minimal, the brief moisture paired with intense heat could create slick conditions on hot road surfaces.
Sunday night will remain warm, with overnight lows only dropping to 74°F under mostly clear skies. The heat continues into Monday, with a high near 103°F and no significant cooling until midweek.
Local emergency services advise residents to check on elderly neighbors, avoid strenuous activities during peak heat hours (1–6 p.m.), and never leave children or pets in vehicles.
No additional watches or warnings have been issued yet, but updates may follow if heat persists into midweek or if monsoonal moisture increases.
