The temparature usually signifies the ambient temparature.
If you notice, often when you keep a steel utensil in the sun, it heats up more than the actual temperature of the day
This indicates that some things absorb heat faster than others
An icecream absorbs heat faster than most things since its way colder.
In a room, the icecream needs to absorb heat from the air
Outside, it can absorb it from the sunlight directly.
Since the rate at which you absorb heat depends on the temperature difference between the two and the temp diff between air and icecream is lesser than temp diff betweeen sunlight and icecream, the icecream absorbs more heat from the sunlight and therefore melts faster

Outside, your ice cream is likely to be exposed to direct sunlight, which has a lot of infrared radiation in it. This particular frequency of light is particularly good at heating things up. So both the sunlight AND the temperature are working against you there.
Indoors, you're not likely to be getting the same level of infrared unless you're standing under a heating lamp, so you only have the temperature effect.

The sun helps it melt faster. Also, winds bring more air into contact with your ice cream causing it to melt faster.

the outside has higher humidity so it has a higher heat index...and it is rare in the summer to have the inside of an icecream place be equal temperature..oh yes, and when the icecream if just taken out of the freezer or just served out, it is still pretty cold, so it may not seem to start to melt for a few minutes, and often by then you are outside...

That would be because of the greater airflow / airspace outdoors. The cold from the ice cream disperses into the greater air supply more quickly.

it... doesn't... if its the same temperature then it melts at the same speeds... unless the sunlight is actually raising th temperature of the ice cream higher than that of the ice cream indoors due to the shade and such...

It's because of the sun, cloudy or not. That is why they came up with the heat index thing. Air flow (wind) probably has something to do with it also.

Direct sunlight outside.

air flow outdoors plus direct sun rays.

maybe cause of the sun is outside not inside and the temp can be different from the heat/ humidity/ uv rays
