Trader consensus on Polymarket assigns a 99.7% implied probability to a high temperature of 69°F or below in Los Angeles on March 25, aligned with the National Weather Service's latest forecast guidance projecting daytime highs in the mid-to-upper 60s. This positioning stems from persistent onshore flow delivering cool marine air from the Pacific, reinforced by low-level stratus clouds and a temperature inversion layer capping warming—conditions evident in recent GOES satellite imagery and model ensembles from NOAA's Global Forecast System and European Centre for Medium-Range Weather Forecasts. March climatology supports this, with Los Angeles' average high near 68°F, and no significant ridging anticipated to disrupt the marine layer through the event window. Realistic challenges include an unexpected offshore wind shift or rapid high-pressure buildup, potentially adding 5–10°F, though ensemble spreads show low likelihood before resolution. New forecast updates are due midday March 24.
