Kathmandu in May is Himalayan pre-monsoon. Department of Hydrology and Meteorology Nepal (DHM Nepal) data put afternoon highs at 29°C / 84°F and overnight lows at 16°C / 61°F with 11 rain days. Kathmandu sits at 1,400m / 4,600ft elevation — mild altitude effects (slightly drier air, sharper UV) but not full mountain-altitude. The dressing register is Nepali heritage layered: lightweight cotton for afternoons, mid-weight cardigan or wool sweater for cool mornings, packable rain shell, slip-on sandals, modest cuts (knee-length minimum; shoulders covered at religious sites — Pashupatinath Hindu temple, Boudhanath Buddhist stupa, Swayambhunath 'Monkey Temple', Patan and Bhaktapur Durbar Squares). The Nepali heritage textile register: Mahaguthi (Kathmandu fair-trade since 1984, the most-cited Nepali fair-trade heritage); Pasang Dolma Sherpa Textiles (Sherpa-heritage handwoven); Jamarko (Nepali handicrafts); Dhaka cloth (the traditional Nepali handwoven cotton with geometric patterns, used for Dhaka topi hat and shawls — the cultural national-heritage textile); Mithila-painted cotton (the Janakpur folk-art painted-cotton tradition). Thamel is the tourist neighborhood with backpacker hotels and trekking-gear shops; Patan (Lalitpur) is the heritage south-of-river district; Bhaktapur (90 minutes east) is the most-preserved Newari heritage town.
Kathmandu May is the Himalayan pre-monsoon turn — 29°C / 84°F afternoons after a cool 16°C / 61°F morning, the Boudhanath stupa-and-prayer-flag white dome at peak photogenic, the Mahaguthi handwoven Dhaka-cloth scarf the most-cited Nepali heritage takeaway.

May is one of the two best trekking windows for Nepal (March-May and September-November). Higher-altitude treks possible: Annapurna Base Camp (4,130m), Annapurna Circuit (5,416m Thorong La), Everest Base Camp (5,364m, requires Lukla flight from Kathmandu), Langtang Valley (3,870m), Manaslu Circuit (5,160m). Pre-monsoon May trekking has clearer skies than post-monsoon September; warmer than autumn. Pack: serious mountaineering layers (down jacket, fleece, moisture-wicking base layers), sturdy hiking boots, trekking poles, sun hat, polarized sunglasses, SPF 50, water purification, altitude-sickness medication (consult travel doctor on Diamox). Use Sherpa Adventure Gear, Black Yak, Marmot for outdoor brands. Hire a registered guide and porter through KEEP (Kathmandu Environmental Education Project) or NMA (Nepal Mountaineering Association).
Generally yes, with standard caution. The Thamel tourist area is well-trafficked but pickpocket vigilance recommended; Pashupatinath and Patan Durbar Square similar. Solo female trekking is documented as low-risk on popular routes (Annapurna, Everest, Langtang) with registered guide-and-porter services. Skip walking alone after dark in less-trafficked areas; Uber-equivalent Pathao or InDrive apps for night transport. Cover shoulders/knees at religious sites and conservative neighborhoods (Old Kathmandu, Patan, Bhaktapur). Pack: modest cotton, Dhaka shawl, slip-on sandals, crossbody bag, hand sanitizer.
