Oslo tech weeks,
and what they do to hotel night one.
Sixteen confirmed dev events fill 2026's Oslo calendar — but only three blocks materially compress downtown room inventory. The grid below colors them in. Mid-September burns hot. Mid-to-late October burns hotter, twice. Everything else is leisure-weekend friendly.

5-day event at Oslo Spektrum, between Jernbanetorget and Grønland. 154 speakers, 14 workshops. Every Sentrum / Grünerløkka hotel takes a price hit. Book 4–6 weeks out [1].
Oct 13 – 23 · 11-day block
Back-to-back. NIC at Oslo Spektrum (13-15) [4], then OIW pulls 16,000 attendees into 50+ city-center venues (19-23) [12]. The 11-day span effectively eats October's middle.
Oct 26 – 27 · Mon → Tue
Scandinavia's biggest UX conference at Chateau Neuf in Majorstuen — hits Frogner / Majorstuen rather than Sentrum, but 2,500+ attendees still bend the market [11].
