מזג האוויר בפארו בדצמבר

Forum posters describe December as genuinely variable day to day - a nice, sunny 18-20C one day, 13C and rainy the next - with average daytime temperatures commonly cited around 16-18C and nights cooling to 8-10C. Posters are consistent it can and does rain, but not all day every day, and that the Algarve's winter climate is generally mild compared to a UK winter even on a wetter day. Posters flag a real seasonal quirk: sun loungers and lifeguards are absent from the beach this time of year, and the sea itself can run rough, so caution near the water is worth noting even on an otherwise pleasant, sunny December day. Posters note many tourist bars and restaurants reopen specifically for the Christmas and New Year stretch after a quieter start to the month.

Regulars are specific this remains a favorite month to visit with rarely any extended rainfall, any rain that does arrive typically a short, sharp shower rather than a settled grey day. Our row backs that mild, genuinely dry read, 23.6C over 16.8C nights feeling 16C, with rain light at 50.7mm across 5.2 days and humidity at 74 percent. Regulars are consistent wind tends to pick up in the evenings, an extra layer worth having even on a warm afternoon, with swimming in a pool or the sea still genuinely pleasant throughout. Temperatures ease toward the high teens by the very end of the month. The sea sits at 20.2C. The record: 9.5 hours of sun, a 23.8 kph wind and AQI 34.

Regulars call late May very nice, not as hot as July or August but warm enough for the beach and a swim, with early May sometimes reported as consistently hot and sunny in its own right - the usual caveat being that weather here is never fully predictable. Our row lands in between, 24.1C reading as 25C over 15.8C nights, with 21.5mm of rain across 3.3 days and a real 26.8 kph wind - regulars specifically flag June through August as this coast's windiest stretch, so May is comparatively calmer already. The trade for coming now rather than June is crowds: Spanish and Portuguese schools do not break up until mid-June, so May keeps the beaches genuinely quiet. The sea is a cooler 17.4C. The record: humidity 69 percent, 12.7 hours of sun and AQI 41.

Regulars call September the best month of the Algarve year - the crowds gone, the summer still running - and give a date for the second drop: after mid-September the Portuguese school term restarts and it quietens again. On weather they promise endless sun and effectively no rain, which our row matches at 8.9mm across 1.3 days under 26.2C. Their sea figure is about 22C and at its yearly peak; ours reads 18C, too cold for this coast in September, so take theirs. Evenings cool to 18.9C and the breeze runs at 24.1 kph. The record: humidity 69 percent, 11.1 hours of sun and AQI 35.

August on this coast is hot and effectively rainless - our row gives 29.6C reading as 31C, with 0.2mm across 0.1 precipitation days - and the question regulars actually argue about is the water. Their answer is that it depends on which current arrived: an Atlantic one puts the sea at 19 or 20C, a Mediterranean-influenced one at 22 or 23. Our row's 18.1C is the cold case, and the eastern Algarve where Faro sits usually runs at the warmer end, so treat the figure as the floor rather than the forecast. Either way it is far colder than the Mediterranean and, with air in the thirties, most people get in anyway. The 26 kph wind is the other thing to plan around. The record: 20.7C nights, humidity 62 percent, 12.6 hours of sun and AQI 39.
