Dressing for 27–30°C outside
Parents don’t experience weather as a single degree — “about 30°C” is how real mornings feel. This guide covers the 27–30°C band, where the outfit usually stays in the same family.
Around 27–30°C outside, keep baby in light short sleeves, a sun hat, and shade. Skip extra layers.
At the cool end (~27°C): At 27°C, a short-sleeve bodysuit or romper plus a sun hat is usually enough. At the warm end (~30°C): At 30°C outside, keep baby in light short sleeves, a sun hat, and shade. Skip extra layers.
Under 6 months, prioritize shade and a brimmed hat over sunscreen (AAP).
The 10-minute chest check
About 10–15 minutes after settling (or outside), feel the chest or back of the neck: warm and dry is right; sweaty means remove a layer; cool means add one. Cool hands and feet alone are normal.
Common mistakes in this band
Overdressing is the usual miss. Pack a spare layer instead of putting it on “just in case.” Under 6 months, prioritize shade over sunscreen.
This is general dressing guidance, not medical advice. Every baby is different — for fever, premature birth, or any medical concern, follow your clinician.
