棉兰 3月 天气

Lake Toba-forum threads on March conditions describe this as a genuine transition month, posters calling the wet season technically still active but noticeably easing compared with the heavier months just prior. Regulars describe the typical pattern as an intense afternoon or overnight shower rather than an all-day soak, mornings on Samosir Island often clear and pleasant. Posters recommend a flexible daily plan given how quickly conditions can shift, boat crossings occasionally suspended during a system. Regulars call the lake's cooler air a real relief against the tropical heat. Posters describe Tuk Tuk as the standard base for exploring Samosir, warm swimming water a genuine highlight regardless of weather. Regulars recommend packing a light rain shell rather than assuming clear skies hold all day. The record: 25.7C days feeling like 30C, 21.4C nights, an extraordinarily high 224mm across nearly 27 days and 85 percent humidity.

Forum posters describe the broader Indonesia dry season, roughly June through August, as generally recommended for travel, though posters note rain remains a near-constant presence across the archipelago's calendar rather than disappearing entirely - a full day of nonstop downpour is unusual, with more typical patterns being a few hours of passing rain followed by sunshine again. It is worth noting that for Medan specifically, the full 12-month climate record shows August is not actually among its driest months - January and February run noticeably drier here, with rain staying elevated from April through December. Posters consistently recommend packing rain gear regardless of the season given how unpredictable North Sumatra's weather can run. Posters generally rate August as warm and genuinely rain-prone for Medan, the wider Indonesian dry-season framing not holding up well for this particular city.

Forum posters describe February as still squarely inside the region's rainy season, with daily rain a real possibility running well into the following months - though posters note February is generally a bit drier than January, even as climate patterns have grown less predictable in recent years. For Medan and North Sumatra specifically, posters describe conditions as genuinely unpredictable day to day, recommending flexibility built into any itinerary through Lake Toba and Berastagi rather than counting on a dry stretch. Posters contrast this with parts of eastern Indonesia like Lombok and Komodo, which tend to run drier at the same time of year for anyone able to adjust their route.
