# Cascais in May: Pretty Much the Sweet Spot

Honestly, if someone asked me when to visit Cascais, May would be near the top of my answer. Not because it’s perfect – nothing is – but because it hits a genuinely good balance that’s hard to argue with.

The weather at 23°C is properly pleasant rather than aggressively hot. You can walk the seafront promenade for an hour without dissolving, sit outside for lunch without needing shade every five minutes, and actually enjoy the beach rather than just surviving it. There’s usually a coastal breeze coming off the Atlantic, which keeps things feeling fresh even on warmer days. That 20mm of rain sounds alarming on paper but in practice it means a handful of grey mornings or an occasional afternoon shower that clears quickly. It’s not the kind of rain that ruins a trip. Pack a light layer and don’t stress about it.

Crowds are manageable in May, which is genuinely one of its best selling points. The summer hordes haven’t arrived yet. You can get a table at a decent restaurant without a reservation, walk around the old town without feeling like you’re in a queue, and actually look at things in the Cascais Museum without someone’s elbow in your face. The beaches have people on them but they’re not sardine-tin levels.

Everything worth visiting is open. Restaurants, the palace at Sintra if you make the short trip, the Boca do Inferno cliff walk, bike rentals along the coast. May is firmly within the operating season for all of it.

Who is May best for? Couples, solo travellers, anyone who likes being outdoors, people who hate crowds, older travellers who find August heat exhausting. It’s less ideal if your kids are desperate for serious beach swimming – the Atlantic is still cold enough in May to make that a short-lived ambition.

**One practical tip:** Book your accommodation earlier than you think you need to. May has grown in popularity significantly and the good places in the town centre do fill up, especially on weekends.
