Cooler air settles in as late summer warmth fades | August 31, 2025

TONIGHT

Skies stay mostly clear; overnight lows ease into the low to mid 50s as a light northwest breeze near 5 mph brings in refreshed and drier air. It feels like the first peaceful breath of fall after a long summer stretch.

TOMORROW

High pressure stays in control with sunshine and comfortable highs in the mid 70s; humidity remains low and a light north northeast breeze around 5 mph keeps the air crisp. This is the kind of Monday that invites you outside for a walk, a bike ride, or a relaxed afternoon at the park.

TOMORROW NIGHT

Clear and calm, with lows dipping into the upper 40s to low 50s; light and variable breezes keep the air fresh. The night is perfect for open window sleep or sitting outside under cool and quiet skies.

TUESDAY

Slightly cooler still, with abundant sunshine and highs in the low 70s; a light north breeze near 5 mph adds to the crispness. The air feels invigorating, almost like an early October day, and it makes for excellent conditions to enjoy the outdoors.

TUESDAY NIGHT

Another cool and tranquil evening with lows in the upper 40s; skies remain mostly clear and winds stay light. A blanket may be needed if you are outside, but the comfort is undeniable.

WEDNESDAY

Midweek brings a gentle rebound in temperatures with highs reaching the upper 70s; sunshine continues and humidity stays low, while a light east northeast breeze near 5 mph makes the day easy and enjoyable.

WEDNESDAY NIGHT

Pleasant and calm with lows near the low 50s; partly cloudy skies develop but conditions remain dry, and light variable winds keep the air balanced and refreshing.

THURSDAY

The run finishes with another day of comfort, highs in the upper 70s under mostly sunny skies, and a light west northwest breeze near 5 mph to reinforce the steady late summer to early fall rhythm.

7 DAY FORECAST

The transition from summer warmth to fall like comfort becomes clear in this stretch. Highs trend from the mid 70s to upper 70s through midweek, with nights falling regularly into the 40s and 50s. Sunshine dominates, humidity stays low, and the overall pattern feels much more like September. This quiet and comfortable setup gives central Indiana a much needed early taste of autumn.
