Good morning Augusta

It’s gonna be hotter ‘n hell out there so use your head and stay the hell out of the heat.

This morning we have areas of patchy fog and partly sunny skies. Warm with highs in the upper 80s with light and variable winds, becoming southwest around 10 mph this afternoon.

Tonight we’ll have mostly clear conditions during evening hours, becoming partly cloudy with patchy fog after midnight. It’ll be humid with lows in the mid 60s. South winds around 10 mph in the evening, becoming light and variable.

The outdoor temperature is 73.8°F, the dewpoint is 69.7°F and it feels like 75.5°F.

We didn’t receive any rain here over the past 24 hours.

Sunrise is 4:56 am, sunset is 8:28 PM and we’ll have 15 hours 31 minutes of daylight today.

Moonrise is 2:43 AM,  Moonset is 7:21 PM. The moon phase is a NEW MOON and is xx% illuminated. Our next full moon will be on July 10 and our next new moon is on June 25.

The wind is from the North between 1.8 MPH and 3.8 MPH.

The Relative pressure is 29.82, the Absolute pressure is 29.62 and rising with a weather graphic indicating sun and a few clouds.

The humidity is 87%, the UV index is 3 placing the average person at moderate risk and the solar radiation reading is 331.8W/M2.

Visibility is 10.0 miles / 16.1 Kilometers with bright, sunny and hot skies.

 

Just exactly what is the UV index?

If you have read How Sunburns and Sun Tans Work, you know that your skin is sensitive to ultraviolet (UV) radiation. The UV index is a value calculated each day that helps you to know how much UV radiation will reach you if you go outside. By knowing the index value for the day, you can take appropriate precautions. These precautions help you avoid sunburn in the short term and skin cancer in the long term.

The UV index is calculated based on four factors:

  • The thickness of the ozone layer over your city (detected using satellites)
  • The cloud cover over your city (clouds block UV radiation to varying degrees)
  • The time of year (in winter, UV radiation is lower than in the summer because of the sun's angle)
  • The elevation of your city (higher elevations get more UV radiation)

The UV index value ranges between 0 and 10, with zero being minimal UV exposure risk and 10 being maximal UV exposure risk. This page lists the proper precautions to take for the different index values.

Bloggers note: If you have kids who want to be on the beach to swim, suntan or build those all-important sand castles I strongly urge you to go to some of the foregoing links and read up on things.
