    Frost appears at what temp?

    Our weather lady has said three or four time frost can appear at 36F, is that true?

    Doesn't that depend on the relative humidity in addition to the temperature?

    Cover your plants tonight or bring them inside, making. Frost can occur at ~36 degrees when the air right at the surface cools to 32 due to evaporative cooling of condensation hat forms on surfaces..

    But the air somewhere has to be 32F, right? I have everything in I can, I know I will lose some blooms if it freezes. According to the news I will be riding in at about 35F. I kinda like it.

    I think it depends on the purity of the water.
    impure water tends to boil and freeze at lower temperatures.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Sure, happens all the time.

    I have a personal weather station mounted at the standard of about 5 feet off the ground. But the ground itself can easily be several degrees colder just a few few lower than the sensor.

    official temp is taken 4 feet above ground. Frost can form at ground level with temp difference between G and G+4

    Thanks everybody, I learn a lot around here. It looks like all my little flowers will be safe, it did not get below 38 and the wind is blowing. The morning weather guy said there should not be any frost south of Indy.

    Yes the ground can be easily 5F less than 6' up.

    Now just what would a resident of Rubenland know about frost?
    Am I an expert on Palm trees?

    Occasionally we get frost in low lying areas, perhaps two, three times a winter. Sometimes actual freezing weather but this is not common. Bradenton and areas south have a climate different than that of Tampa Bay area. In Bradenton coconut trees flourish along with mango's, leeches, and other sub-tropical species but north of Bradenton, you are fooling yourself with sub tropical plants.

    There are ancient Indian mounds scattered around Bradenton and Palmetto, FL. These mounds are sometimes 25 feet high maybe more. But on top of these mounds grow trees that will never grow anywhere else. The tropical trees and plants flourish on these mounds as the 25 foot altitude now lets tropical's grow without fear of frost of freeze. Kind of neat actually. Species of trees found in the Keys can be found on these Indian shell mounds.

    Yea, kinda neat. I fished the Suwanne River one year, oh probably about 86 or 87 there was soild ice on the eyes on my fishing rod. The interstate was frozen and the natives were pouring hot water on their windshield cause they did not have scrapers cracking them. It was a zoo, but entertaining. The day we left it was 80F+. Oh on the way there, in MS I think it was so cold we stopped for breakfeast and the resturant did not have a real heather, the plate was soo cold it busted with the biscuits and gravey poured on it.

    At night, especially when the sky is clear, outdoor surfaces can cool considerably below the ambient air temperature as a result of radiating heat away to the night sky. Windshields of cars parked out in the open will have frost form earlier than if they are parked where much of the sky is blocked by trees or buildings. This radiational cooling is also what causes condensation on exposed surfaces overnight even when the ambient air temperature stays well above the dew point.
