Indianapolis is starting Tuesday with calm winds and temperatures in the low 50s, but the day will warm quickly. Patchy fog could linger through midmorning before partly sunny skies take over and temperatures climb to about 74 degrees.
Foggy Start, Warm Afternoon
The fog should clear before 10 a.m., with light southeast winds and no meaningful rain threat during the day. Tuesday night will be partly cloudy, with temperatures dipping to around 48 degrees.
Warm Weather Holds Through Friday
Wednesday will be mostly sunny with a high near 75, followed by an even warmer Thursday that could reach 78 degrees. Thursday’s southwest winds may gust up to 20 mph, while Friday stays mostly sunny and warmer than normal.
Rain Chances Rise For Halloween Weekend
The pattern turns wetter Saturday night, with showers mainly after midnight. Rain chances increase Saturday night and peak Sunday, when showers are likely and the high should reach the mid to upper 60s; Monday brings another chance of showers with a high in the mid to upper 60s.
How This Forecast Compares With October Normals
For seasonal context, the National Weather Service’s Indianapolis Weather Forecast Office lists Indianapolis’s normal October temperature as 55.5 degrees. That is a monthly average, not a normal daily high, so it does not establish how unusual highs in the 70s are; the figure also does not show how unusual late-October rain is.
