Charleston is in for an unpredictable stretch of weather that will test residents’ ability to adapt. The city will see everything from thick morning fog and warm temperatures to thunderstorms, gusty winds, and a sharp cool-down.
If you’re making weekend plans or expecting smooth commutes, you’ll want to stay ahead of the forecast—this week’s weather won’t stay the same for long.
When Will the Biggest Weather Shifts Happen?
Wednesday, February 12 – The day starts with dense morning fog, which could reduce visibility to dangerous levels. Once the fog lifts, expect mostly cloudy skies and a mild high of 65°F (18°C). Light southerly winds will keep things comfortable, but be cautious if driving early in the morning.
Wednesday Night – Skies will remain mostly cloudy, with temperatures staying mild at 62°F (17°C). Winds will pick up slightly but remain manageable.
Thursday, February 13 – A major shift begins. After a calm morning, thunderstorms and showers will develop in the afternoon, with gusty winds up to 24 mph. Some storms could bring heavy rain and brief flooding. Despite the stormy conditions, temperatures will climb to 71°F (22°C) before plummeting overnight.
Thursday Night – As the rain clears, temperatures will drop dramatically to 44°F (7°C). Winds will shift to the north, bringing in colder, drier air.
Friday, February 14 (Valentine’s Day) – The storms will be gone, but cooler air settles in. Expect sunny skies with a crisp high of 58°F (14°C). If you’re planning an outdoor dinner or a waterfront walk, bring a jacket—it’ll feel much colder than earlier in the week.
Saturday, February 15 – The warm-up begins again. A mix of clouds and sunshine will push temperatures back up to 71°F (22°C). However, a 40% chance of showers lingers, so keep an eye on the radar.
Sunday, February 16 – Another storm system moves in. Expect showers and possibly a thunderstorm, with an 80% chance of rain. Temperatures will stay in the low 70s, but gusty winds and heavy rainfall could cause localized flooding.
What This Means for Charleston Residents
With foggy mornings, a big midweek storm, a sudden temperature drop, and another wet weekend, Charleston residents will need to be prepared for anything.
- Morning commutes could be dangerous due to dense fog on Wednesday. Drivers should slow down and use low-beam headlights to improve visibility.
- Thursday’s storms could bring downpours and strong winds. Secure loose outdoor items and be cautious of flooded roads.
- A sudden temperature drop Thursday night means you’ll need a jacket by Friday. The sudden shift could also trigger allergies and cold symptoms.
- Weekend plans may be disrupted by rain. Saturday looks decent, but Sunday could be a washout. If you have outdoor plans, Saturday is your best bet.
How to Stay Safe and Prepared
- Be extra cautious while driving on foggy mornings. If visibility is poor, keep headlights on low beam and increase following distance.
- Watch out for severe weather Thursday. Thunderstorms could bring strong winds and heavy rain, so avoid unnecessary travel during peak storm hours.
- Prepare for temperature swings. One day will feel like spring, the next will feel like winter. Dressing in layers will help adjust to the rapid changes.
- Expect a wet Sunday. If you’re heading out for weekend events, bring an umbrella and prepare for possible delays due to rain.
Final Thoughts
Charleston’s weather is all over the place this week—but if you stay ahead of the changes, you can navigate it safely.
With foggy mornings, afternoon storms, and a weekend rainmaker, residents should plan for unpredictable conditions and stay updated on the latest forecasts.
By driving carefully, dressing for the temperature swings, and staying indoors during storms, you can make the most of Charleston’s wild weather ride.
