**Persistent high pressure and a strong late-August heat wave are keeping overnight lows elevated across Los Angeles, with official National Weather Service and NOAA forecasts pointing to a minimum temperature in the mid-70s on August 27.** Weak onshore gradients, suppressed marine-layer development, and warm ocean waters have limited nocturnal cooling, producing lows well above the historical August average of ~65°F. Current model consensus and NWS point forecasts indicate 72–76°F as the most probable range for the daily minimum, consistent with the closely matched market probabilities clustered around 72–77°F. Slight variations in exact timing of any residual onshore breeze or cloud cover could nudge readings toward the lower- or upper-70s, while an unexpected strengthening of the ridge would favor the higher end; later-week cooling is not expected until after the 27th.
