Marine layer clouds and persistent onshore flow from cooler Pacific waters remain the dominant factors capping daytime heating in coastal Los Angeles on July 5, keeping official highs most likely in the low-to-mid 70s. Recent National Weather Service guidance and ensemble model runs show only modest reduction in morning stratus, with light southwest winds and weak pressure gradients limiting afternoon warming compared to the seasonal 81°F average. Traders assign nearly identical probabilities to the 72–73°F and 74–75°F brackets because small differences in marine layer clearance timing or localized sea-surface temperatures can shift the peak by a degree or two, while the risk of stronger clearing pushing readings into the upper 70s stays low. This setup aligns with typical early-July coastal moderation rather than inland peaks.
