Dehydrated ?

Hi everyone so first baby and of course I’m a worrier. We live east coast of Canada and aren’t accustomed to the warmest of weather. Today we had a beautiful 30 degrees Celsius and the baby was out for about an hour in the morning and perhaps an hour and a half in the late afternoon, she was sipping water all day and had her regular bottles. I noticed when I took her diaper off for bath Time it was really light not it’s usual sogginess, she had 8 oz of milk before bed and then I got a little worried and gave her another 3 and now trying to give her water even though she’s sound asleep. Am I just being super paranoid?
