Været i Hilton Head Island i februar

Regulars are specific about two things in February: it is too early for the main azalea display, which they date to mid-March, though a few blooms show up early in the sunniest spots; and the coast runs about ten degrees warmer than Atlanta while still needing a real jacket after dark. Our row backs both, 20.5C reading as 20C over 8.4C nights feeling 6C, with 70.4mm of rain across 5.7 days. The advantage of the month is crowds rather than blooms - January is slow and February only picks up gradually, well ahead of the high rates and booked-out hotels that spring brings with its flowers. The record: humidity 76 percent, 7.9 hours of sun, a 22 kph wind and AQI 40.

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.

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.

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.
