Split climate — Mediterranean, with a brutal summer peak
Split has a Mediterranean climate: hot, dry summers and mild, wet winters. The city sees around 2,600 sunshine hours per year — more than Porto, comparable to Barcelona. The Adriatic keeps temperatures more stable than inland Croatia, but July and August still hit 30-35°C regularly and 38°C is not unusual during heatwaves. Winters are mild by European standards (5-12°C), but November through February bring real rain — 13-17 rainy days a month.
For remote work, the takeaway is simple: shoulder season is the sweet spot. May, June, September, and October give you 18-26°C, manageable tourist density, long daylight hours, and no heat-induced afternoon shutdowns.

Best months for remote workers
May and June are the sweet spot before the tourist wall hits. Temperatures run 17-25°C, the sea warms enough for a post-work swim by late May, and rain tapers fast. June 2 — just two rain days on average — is the driest month. Daylight stretches to 21:00.
September and October are the other ideal window. Sea is still warm from summer (22-24°C into mid-October), tourists thin out after the first week of September, and temperatures settle at a workable 15-22°C.
July and August are hot and chaotic. 25-30°C average masks frequent 35°C+ afternoons, Grad is shoulder-to-shoulder with cruise tourists by 10:00, and short-term rental prices double or triple. Coworking is essential because air-conditioned apartments become the only place to focus. If you must come in high summer, base yourself in Manuš or Bačvice over Grad itself.
November through February is quiet, grey, and cheap. Expect 12-17 rain days a month, temperatures 8-12°C, and many seasonal cafes, restaurants, and ferries running reduced schedules. The upside: rents drop 30-40 % and the city returns to locals. Good for focused winter work if you don’t need sunshine for morale.
What to pack
May-October: Light layers, swimsuit, sunglasses, sunscreen (the Adriatic sun is sharp). A light sweater for evenings in May and September. Comfortable shoes — the polished limestone streets of Grad are slippery when wet.
July-August: Everything you’d pack for Barcelona in August. Breathable fabrics, reef-safe sunscreen, a hat. Skip anything heavy — you won’t wear it.
November-April: Waterproof jacket (skip the umbrella — bura winds destroy them), warm layers for 5-12°C mornings, waterproof shoes. A decent rain shell is worth investing in.
Year-round: Laptop sleeve with weather protection. Split’s limestone gets genuinely slippery in rain — good grip soles matter more than style.
