サバンナには9月のメモがまだありません — これは季節を共にする近くのヒルトンヘッドアイランドについてのメモです。
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.

Regulars call this a genuinely fantastic month, warm without yet tipping into the thick, oppressive humidity that defines June onward, with sunny days in the 80s Fahrenheit and rain chances still comparatively low. Our row backs that warm, still-manageable read, 29.3C reading as a hot 31C, over 18.2C nights, with 99.1mm of rain across 6.9 days and humidity at 73 percent. Regulars are specific this window is worth prioritizing over deep summer for anyone planning to walk the historic squares extensively, since the heat index climbs sharply just weeks later. Light, breathable fabrics remain the standard packing advice even this early. The record: 11.2 hours of sun, a 21.4 kph wind and AQI 46.
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 call November the start of the southern autumn and then manage the expectation it creates: this is a semitropical city of live oaks, so it stays green, and anyone arriving for northern colour will find some dark red and brown leaves on the ground by the end of the month and nothing scenic. What the month is for is walking - the squares, the riverfront, and the beach out at Tybee - with everything open year-round. Their averages of 71F and 48F are our 21.5C over 9.9C, warm by day and chilly after dark, and about 18C around Thanksgiving. The record: 73.9mm across 6.8 days, humidity 75 percent, 7.9 hours of sun and AQI 35.
Late March in Savannah is close to perfect by the forum's reckoning - days of 60F and better, some cool nights, and the dogwoods and azaleas coming out from about mid-month. Our row gives 22.9C days against 10.6C nights, which is that cool-night gap in figures. Three caveats they raise. There is usually one more cold spell between early March and St Patrick's Day, with nights below 40F. The 17th itself is the one date to avoid unless the crowds are the point, because the festival fills the town. And gnat season starts in March and runs to May. The record: 6 precipitation days carrying 80.5mm, a 22.8 kph wind and 9.3 hours of sun.
