Været i Sylhet i mai

Forum posters describe July as squarely within Bangladesh's monsoon, with constant rain throughout the month and heat that makes getting around genuinely uncomfortable between downpours. Posters are direct that despite this, June through September counts as high season for some of Sylhet's signature natural attractions specifically because of the rain - Bisnakandi is recommended for exactly July and August, and the Ratargul Swamp Forest, one of the few swamp forests in Asia, is best visited by boat during the May-to-October monsoon precisely because the rising water lets you glide directly among the trees. Posters generally frame the constant rain as the trade-off for seeing these flooded-forest and waterfall attractions at their most dramatic. Posters generally rate July as heavily monsoon-affected and physically demanding for general travel in Sylhet, but genuinely rewarding for visitors specifically prioritizing its wetland and waterfall attractions at their peak.

Forum posters place late October through early March as Bangladesh's best general travel window, putting January squarely inside it. For the Sylhet tea gardens specifically, posters note there's a lean period from the third week of December through the second week of March when no tea is harvested - this is pruning season, so January visitors see far less picking activity and less vivid green than during the main harvest months, though the gardens, tea-worker villages and nearby tribal villages remain open and worth visiting regardless.
