Wetter in Hilton Head Island nach Monat

April on Hilton Head is upper 70s to low 80s F by day and near 60 at night, with the caveat that early April is the unpredictable part and some years want jeans and a sweatshirt for most of a week. The ocean is the honest limitation: around 68F, which regulars call fine for wading and not for staying in, and the standing suggestion is a place with a heated pool so the beach and the swimming can be separate decisions. The crowd calendar has one date on it - the Heritage golf tournament in early-to-mid April fills the hotels, the restaurants and the shops, and Easter week does the same. The record: 24C days, 15.6C nights, 5.9 precipitation days, 10.8 hours of sun, a 20.9C sea and a 22 kph wind.

Hilton Head's forum calls late May the sweet spot — warm enough for the beach and pool, genuinely rare to get as hot as July or August, roughly one day in four or five bringing rain, usually late afternoon or evening. Regulars note the ocean is swimmable but not warm, and that May stays noticeably quieter than the June-through-August rush since most schools are still in session.

Regulars call this a genuinely nice month - hot, but not July or August hot, with a steady ocean breeze regulars credit for keeping the beach comfortable even as humidity builds through the month. Our row backs the heat, 30.5C reading as 35C at 78.3 percent humidity, over 23.5C nights, with 139.9mm of rain across 9.6 days. The sea is refreshingly cool rather than warm at 26C, murky enough that stingrays are only visible in the shallowest water. Gnats are the one insect regulars flag as temperature-triggered rather than seasonal outright - worst in the low seventies Fahrenheit, so a cooler June week can bring them out where a hotter one keeps them away. Beaches stay noticeably less crowded than July. The record: 11.5 hours of sun, a 19.8 kph wind and AQI 54.

Regulars are specific it's genuinely the humidity more than the raw heat that makes this month tough, though a steady breeze helps take the edge off, evening thunder showers a near-daily feature that typically clear within 10 to 30 minutes rather than settling in. Our row backs that hot, genuinely wet read, 32.2C reading as a scorching 37C, over 25.3C nights feeling 30C, with a substantial 203.4mm of rain across 10.5 days and humidity at 79 percent. Regulars are consistent both the very start and the later weeks of the month run noticeably more crowded, a quieter mid-month stretch the practical workaround for anyone avoiding peak traffic. The sea sits at a bath-warm 30.4C. The record: 11.9 hours of sun, an 18.7 kph wind and AQI 68.

Asked whether hurricane season should put them off September, regulars answer with geography and lead time rather than reassurance: the island sits in an unlikely spot for a direct landfall, and a storm that does threaten gives several days of warning, so the decision can be made late. What they sell the month on is the emptiness - the summer crowds have gone, the water is still warm at 28.2C, and the temperatures are comfortable at 29.4C over 22.8C. They are also honest that September is among the wettest months, quoting about five inches; our row has 157.2mm falling across just 7.1 days, twenty-two millimetres each. The record: humidity 79 percent, 9.9 hours of sun and a 19.8 kph wind.

October is the month locals name for Hilton Head, and their figure - an average high of 76F, usually in the 70s and sometimes the 80s - sits just under our row's 25.7C. The water is the part that changes through the month: still warm enough to swim in early October, down to the high 60s Fahrenheit by the end, with our 22.7C the average of the two. Everything else about the month is quieter. The children are back at school, so the crowd turns to golf and tennis, and rates and rentals are discounted. On hurricanes they are matter-of-fact: this is officially the last month of the season, and residents point out the island has not had one in over a century and has evacuated twice in thirty years. The record: 18.2C nights, 77.8mm across just 4.8 precipitation days, 9.1 hours of sun and AQI 41.

Forum posters describe November as genuinely variable year to year - one long-time Thanksgiving-week visitor reported both an 80sF year warm enough to swim and a separate year with sleet on Thanksgiving Day itself. Typical conditions run more moderate: highs around 72F easing to the low-60s by late November, with mornings and evenings crisp enough for a jacket or light layers even on an otherwise mild day. Posters generally describe November as sunny, comfortably warm rather than hot, and low-humidity - good outdoor-activity weather overall, with the year-to-year temperature swing being the main thing to hedge against rather than a fixed expectation either way.
