Race-morning weather history
2015 edition hit ~90F March heat with mass medical incidents, prompting earlier start times in later years. Wyndo tracks what this calendar slot has actually served up at the start hour — temperature, dew point, wind, and rain — including the years when weather canceled or disrupted the race, and reads the live forecast for the start once the race confirms its schedule and race week arrives.
The Los Angeles Marathon moves around the calendar year to year (A Sunday in early-to-mid March (exact week varies year to year — do not encode a fixed-week rule)), so there's no fixed slot for year-by-year history. A table based on estimated dates could put the race in the wrong weather, so we don't show one. We're sourcing the real past edition dates by hand; the history lands here when they do.
