Weather in March?

Light layers should be enough but it will depend on how cold (or warm) is too cold for you...The last time I went in April, the daytime was fine for light trousers and t-shirts but the evening got a bit cooler and needed a thin sweater to keep out the chill. Also, not sure whether the polar vector has affected the temps in Florida too much or not...?

Our weather here in March is typically light cardigan(nighttime only) and flip flop weather. It is typically high 70's to low 80's, during the day and high 60's(but not cold) at night. If you are someone that get's cold easily, bring a heavier sweater or jacket for the nighttime. But March weather here in Florida is beautiful!

High 60's sounds like shorts ant t-shirt weather to me

High 60's in Scotland is like Death Valley in America..

Well, my experiences is that it's pretty warm generally speaking. I recall most of my time during my last three trips (All of them were in March), temps were in the upper 70s, lower 80s for the most part. I think there was only one day I recall where it was the mid to upper 80s but never 90. At night, it cools down a bit to the 60s so I tend to wear a light spring jacket for the night.

When I was there in March last year (though I didn't do the parks), it was very, very much shorts/tank or shirt sleeve weather for me. We did Braves Spring Training games and sitting out in the sun for 2-3 hours got HOT. At night it got cooler, but I was still out in shorts, though I threw on like a denim/chambray shirt with the sleeves rolled up over a tank top, or I'd throw on a really light cardigan. Super, super enjoyable weather aside from sitting out in the hot sun with no shade to watch my baseball babes play.

I have a Scottish friend who feels like that too...! haha!
