After an intense heat wave scorched much of the state, South Carolina now faces a summer outlook that remains unrelentingly hot, according to updated forecasts from the National Weather Service and the Farmers’ Almanac.
South Carolina, particularly the Midlands, experienced oppressive heat earlier this week, with the heat index soaring well into the triple digits on Wednesday. The NWS issued heat advisories across the region on Tuesday and Wednesday, warning of dangerously high temperatures.
As June winds down, storms and rain are bringing some short-term relief, but meteorological projections for July, August and early September indicate a return to extreme warmth.
Forecast from the National Weather Service: hot and wetter than usual
The NWS Climate Prediction Center assigns a 40% to 50% probability of above-average temperatures across South Carolina during July, August, and September. While summer officially ends September 22, the forecast shows that much of the season could be dominated by oppressive heat.
In addition to high temperatures, the Palmetto State also faces a 40% to 50% chance of above-normal rainfall during this period. This suggests a humid, storm-prone pattern, especially during the latter half of summer, which often coincides with tropical storm activity.
Farmers’ Almanac summer forecast: thunderstorms, heat, and hurricanes
According to the Farmers’ Almanac, most of the United States, including the Southeast, will experience above-average temperatures this summer. For South Carolina, the forecast calls for intense heat to kick off July, leading straight into thunderstorms around Independence Day.
The middle of July is expected to remain hot with minimal precipitation, followed by a stormy, humid end to the month.
As August begins, mostly clear skies are likely, but August 8–11 brings a potential hurricane threat forming near the Florida coast and possibly impacting the Southeast, including South Carolina.
Between August 16–19, more thunderstorms are forecast across the Carolinas, transitioning into humid, showery days and scattered storms through the end of August.
Labor Day weekend may see a brief break in thunderstorms, but September 4–7 is likely to feature widespread thunderstorm activity. The middle of September raises the risk of another hurricane threat along the Atlantic seaboard, followed by persistent rain and storms until around September 20, when clear skies are finally expected to return.
A look at how the Farmers’ Almanac forecasts
Founded in 1818, the Farmers’ Almanac relies on a proprietary formula involving factors such as sunspot activity, planetary positions, and tidal patterns to issue its long-range weather predictions, which are compiled as far as two years in advance.
Despite the secrecy of its methodology, long-time followers of the Almanac estimate its accuracy to fall between 80% and 85%, making it a popular reference for those looking to prepare for seasonal weather conditions across the United States.
