Month-Long Weather Progression: Early vs. Late May
The weather experience shifts noticeably between the first and last days of the month. Travelers scheduling a vacation should evaluate these distinct phases to optimize their itinerary.
Early May Conditions
The first ten days of the month often carry lingering spring freshness. Morning temperatures can feel brisk, hovering around 55°F to 58°F, requiring a light jacket or sweater for early morning walks along the boardwalk or MarshWalk in Murrells Inlet. Afternoon highs stabilize near 75°F to 78°F.

Evening temperatures remain mild in the low 60s.
