Het weer in Funchal (Madeira) in augustus

Madeira's forum calls August the hottest, sunniest, busiest month on the island, with regulars flagging strong UV and humidity as the real concerns rather than rain, which stays rare. The island's well-known microclimates mean conditions can differ sharply from one town to the next — Calheta gets singled out as the more reliably sunny spot if the forecast elsewhere looks mixed.

Regulars call this a favorite month specifically for the jacaranda trees still in full, spectacular bloom, sunny and genuinely warm without tipping into summer's heat, and notably free of the humidity that can make walking uncomfortable elsewhere. Our row backs that mild, still-dry read, 22.3C over 16.5C nights, with rain light at 24.3mm across 7.3 days and humidity at 74 percent. Regulars are consistent the island's real microclimates make forecasting more than a few days out genuinely unreliable, one side of the island running sunny while another sees a passing shower at the same time. This remains a genuinely comfortable month overall for the levada walks the island is known for. The sea sits at a comfortably swimmable 21.1C. The record: 12.4 hours of sun, a 14 kph wind and AQI 45.

Locals call June the blanket month, for the cloud that settles over the island - and the important half of that phrase is where it settles. The mountains take it; the south coast, where this city sits, is usually warm and sunny underneath. So the answer depends on the plan: the promenade and the sea front are mostly fine, levada walks up in the interior are far likelier to be inside cloud, and a lightweight gilet earns its place up there. The warning regulars repeat is UV rather than heat - it burns faster than you expect even on a dull day. Our row is mild and steady, 23.8C reading as 26C over 18.5C nights, with 29.1mm of rain across 5.9 days, a 22C sea and 12.9 hours of sun. The record: humidity 74 percent and AQI 41.

Madeira-forum threads on December visits describe Funchal as warm enough by day for shorts and a t-shirt on a good stretch, daytime readings comfortably in the low-to-mid 20s Celsius, but posters are consistent that sunshine is never guaranteed - genuinely pleasant days sit right alongside cloudy, wet, windy ones, sometimes within the same week. Evenings turn noticeably cooler regardless of how the day went, a light jacket or sweater the standing recommendation after dark. The island's famous microclimates mean the north coast sees meaningfully more rain than Funchal itself on the sheltered south side, worth knowing when picking a base. The one thing regulars agree on: December is a strong month for the city's Christmas lights display, reason enough for some repeat visitors to plan a trip around this month regardless of the weather roulette. The record: 20.9C days feeling like 20C, 15.7C nights, 58mm across 10.8 days, a 21.4C sea, 78 percent humidity and 8.3 hours of sun.

September is when the sea around Madeira is at its warmest - regulars say at least 24C, and our row gives 24.8C - which makes it the swimming month rather than August. The qualification they always add is where: large stretches of this coast are not safe for open-water swimming, so the lidos and the sheltered bathing complexes are the answer, not the nearest bit of shoreline. On land it is sunny with the occasional cloudy or wet day, days in the low-to-mid twenties, and the humidity has begun to drop from its summer peak. Our row's 26.2C reads as 29C, so the levadas are the smart daytime plan: most of those walks run in shade. The record: 20.4C nights, 17.4mm across 6.3 days, 11.2 hours of sun and AQI 40.
