Recent National Weather Service and model guidance indicate the daily minimum for Los Angeles on August 28 will likely occur overnight under lingering warm, humid conditions from the current heat wave, with forecast lows in the lower to mid-70s at downtown and coastal stations. Elevated sea-surface temperatures have suppressed typical marine-layer cooling, keeping overnight minima several degrees above the 1991–2020 average of 65 °F and supporting the market’s clustering around 72–75 °F buckets. A gradual onshore flow increase and the expected end of the extreme-heat warning after Friday evening introduce modest downside risk, which traders appear to price into the 67 °F-or-below outcome. Updated NHC and local model runs through the weekend will clarify whether the warm airmass lingers or yields earlier radiational cooling.
