Hamilton weather in September

Regulars are specific that daytime temperatures typically run in the low-to-mid 70s Fahrenheit with cooler evenings in the mid-60s, and the first week of the month usually isn't real beach weather even if a warm afternoon can nudge into the low 70s. Our row backs that mild, genuinely wet and windy read, 22.4C over 17.4C nights feeling 15C, with a substantial 73.9mm of rain across 9.8 days and a real 33.6 kph wind. Regulars are consistent this remains pleasant enough for general touring, golf, tennis and walking rather than swimming, most visitors waiting for the water itself to warm up later in the season. The sea sits at a cool 20.9C, still too brisk for a comfortable swim for most. The record: humidity 75 percent, 10.8 hours of sun and AQI 49.

Regulars call this possibly the best month of the year here, with low-to-moderate humidity by the island's own standards and daytime temperatures in the comfortable low-to-high 70s to low 80s Fahrenheit range - though one thread specifically flags this as the month humidity starts climbing toward its May-through-August peak, hitting 80 percent in town. Our row backs the warm, increasingly humid read, 27.4C reading as a real 30C at 82 percent humidity, over 22.7C nights, with 123.1mm of rain across 14.2 days - regulars describe showers as typically brief and localized rather than washing out a full day. The sea sits at a swimmable 24.2C. The record: 11.5 hours of sun, a 26.1 kph wind and AQI 41.

Bermuda-forum threads on October weather call it genuinely one of the best months of the year - daytime temperatures still comfortably in the high 70s to low 80s Fahrenheit, ocean water in the mid-to-high 70s and still good for swimming, without summer's peak crowds or prices. The catch regulars are upfront about: the chance of a longer rain stretch climbs compared to June or July, conditions less predictable this late in the season. Hurricane season technically runs through November, but posters are consistent that a direct hit is rare - Bermuda gets brushed by storms far more often than actually struck. Travel insurance still gets recommended as a low-cost precaution rather than a sign the risk is high. The record: 26.8C days feeling like 28C, 22.1C nights, a notably high 141mm across 13.5 days, a 25.9C sea, 75 percent humidity and wind averaging nearly 33 km/h.

May is the month Bermuda's swimming season opens, and the forum's figures move fast inside it: the water runs cooler in early May and reaches the high 70s Fahrenheit by the end, occasionally into the low 80s, with our row's monthly 21.7C sitting at the cool end of that arc. Air temperatures they give as low-to-mid 70s rising to the low 80s - our row says 24.8C over 20C. The real selling point is rain, or the lack of it: May has the fewest wet days of the Bermudian year and the showers that come are brief, which our row renders as 9.1 precipitation days carrying 96.9mm, brief and heavy rather than persistent. The record: feels-like 26C, humidity 80 percent, a 27.9 kph wind and 11.5 hours of sun.
