Farmer’s Almanac extended forecast

The Farmers’ Almanac summer weather forecast calls for a warm, hot and muggy summer for most of the country. The southeast in particular experiences downpours and steamy days.

According to Farmers’ Almanac, the weeks of June 8 and 16 will see an increase in humidity and more thunderstorms in South Carolina. Expect the month to end with humidity and more thunderstorms.

Expect a period of hot but dry weather the week of July 4, followed by a week of heavy rain. More thunderstorms and high temperatures are forecast at the end of July.

The rainfall will continue into August. Temperatures are expected to be ‘oppressively hot’ in the week of August 8. Don’t expect rain chances to decrease in late August, but temperatures should cool somewhat, according to Farmers’ Almanac.

How Farmer’s Almanac predicts the weather

The Farmers’ Almanac, founded in 1818, uses a secret formula that includes components such as “sunspot activity, tidal action, the position of the planet” to predict long-term weather forecasts. The forecasts are usually made two years in advance. Fans of the Farmers’ Almanac have calculated over the years that the predictions are accurate 80-85% of the time.

Recommended thermostat setting

The U.S. Department of Energy recommends setting your air conditioner to 78 degrees in the summer. The idea is that for every degree above 78 degrees, you will save 10% on your energy bill. Otherwise, you spend 10% for every degree you go below 78 degrees.

Stay comfortable

Carolina Comfort Inc., a Columbia-based HVAC company, notes that 78 degrees can still be stuffy, especially in places like the Midlands because of the high humidity.

“This is because the heating and cooling system simply will not run long enough to bring the humidity in the home below 50% relative humidity, which is ideal for most people,” according to the company’s website.

To combat that feeling, the company suggests using ceiling fans as well.

“By running the ceiling fans in your home, you move the cool air; also, the air movement will help eliminate hot and cold spots that may be present in the home,” the website says.

Energy saving tips

Dominion Energy has several tips to help South Carolina residents save money on their energy bills this summer.

  • Check the air filters monthly and replace them if they are dirty
  • Check your ducts regularly for leaks or cracks
  • Have your central heating and cooling system serviced annually
  • Upgrade your attic insulation to at least R-38 (12-14 inches)
  • Caulk, caulk and weather strip around all seams, cracks and openings
  • Install a door sweep to seal the gap between the bottom of your door and the threshold
