Salvador weather in December

December is one of the three months regulars name for Bahia, with November and January, on the grounds that this is when the cloud clears and the sun is most reliable. The Salvador rains run April to August and arrive as bursts of 15 to 90 minutes rather than all-day weather, which is why our row's 10.5 precipitation days carrying only 49.3mm still describes a dry, bright month. It is high Brazilian summer, so the heat is the trade: 31.9C reading as 36C at 76 percent humidity, with the 20.9 kph sea breeze doing most of the cooling. The record: 24.4C nights, 11.4 hours of sun, a 26.5C sea and AQI 34.

Regulars with long personal experience here are direct that this month simply isn't dramatic weather-wise despite technically falling within the May-to-September rainy season, most rain arriving as quick 10-to-20-minute showers locally called chuva rapida rather than a settled wet day. Our row backs that warm, genuinely wet read, 28.1C reading as a hot 30C, over 22.1C nights, with 92.7mm of rain across over 20 days and humidity at 77 percent. Regulars are honest that some years do bring genuinely too much rain and wind for reliable beach time, so this remains real variability rather than a guarantee either way. The sea sits at a warm, swimmable 26C. The record: 10.6 hours of sun, a 20.2 kph wind and AQI 40.

Regulars name the driest months as November through January, which places February just past that peak and still firmly in Brazilian summer - hot and humid, one visitor calling it full summer weather. Our row backs the heat, 32.5C reading as 37C at 76.4 percent humidity, over 25C nights, with 51.7mm of rain across 14.7 days. The city's population roughly doubles for Carnival, which regulars date to around the 12th of the month though it moves with the wider calendar each year, and petty crime rises sharply enough that extra police get drafted in specifically for the event. The sea is a warm 28.1C. Anyone timing a trip around the festival should check that year's exact date rather than assume mid-February. The record: 11.4 hours of sun, a 20.3 kph wind and AQI 36.

Salvador-forum threads on real-life March and April weather experiences confirm this sits inside the region's rainier stretch, hot and muggy with a real chance of a soaking shower most days, but posters are candid that actual trip reports vary a fair amount - one visitor's late-March into early-April stay turned out excellent, sunny stretches outnumbering the wet ones despite the calendar's rainy-season label. Regulars steer travelers with flexible dates toward October through February instead, the genuinely drier window on Bahia's coast, but are equally clear March remains entirely visitable provided a traveler packs for rain. The historic Pelourinho district is called worth exploring rain or shine, its covered colonial arcades offering natural shelter between showers. The record: 32C days feeling like a sticky 36C, 24.9C nights, a notably high 123mm across 18.7 days, 78 percent humidity, a 28.6C sea and 10.9 hours of sun.

September is where Bahia's wet half of the year ends and the sunny stretch begins - the forum puts the best odds of sun from September through March - with temperatures around 28C and what regulars describe as a very nice climate. Their description of the rain is the useful part and matches our own row better than a monthly total would: showers last five to thirty minutes, one or two a day, rather than settling in. Our record shows 17.3 precipitation days carrying only 66.2mm, which is exactly that pattern - frequent, brief and light. The rest: 28.9C days that feel like 31C, 22.5C nights, 10.8 hours of sun and a 26.1C sea.
