Trader consensus on Polymarket closely splits between 70-71°F (37%) and 72-73°F (34.5%) for Los Angeles' highest temperature today, reflecting National Weather Service guidance and recent GFS/ECMWF ensemble runs projecting peaks in the low 70s amid persistent onshore flow and a deepening marine layer. This follows a historic March heat wave with multiple record highs earlier in the month, but yesterday's Area Forecast Discussion from the Los Angeles/Oxnard office notes ridge breakdown allowing stratus clouds to erode slowly, capping insolation and favoring coastal sites like LAX around 71°F. Key differentiator: earlier marine layer burn-off by midday could enable 1-2°F extra solar heating for 72-73°F, while prolonged low clouds limit it to 70-71°F; light sea breezes (5-10 mph) add uncertainty, with hourly observations through afternoon providing resolution clues. Above-normal for March norms (68°F average), but no extreme heat risk remains.
