Latest National Weather Service guidance and ensemble means from GFS and ECMWF models project a high temperature near 67-69°F at Los Angeles International Airport (LAX) on April 1, mirroring trader-implied probabilities clustered tightly around those ranges and reflecting coastal spring climatology with average highs of 67°F. The close contest stems from uncertainty in marine layer persistence—persistent stratocumulus clouds and moderate onshore flow could cap peaks at 66-67°F, while earlier burn-off and diurnal heating under weak high pressure might push 68-69°F. No major developments in the past week have shifted patterns, but daily 12Z model runs and NWS updates through tomorrow could refine odds amid typical 5°F forecast spread for LA Basin.
