The packing list that checks the weather first
Tell Mabel where you're going and when. She checks the actual forecast and seasonal patterns, then builds a packing list around real conditions, not vibes.
Everyone packs for the destination in their head. Lisbon is sunny, so you pack sunny, and then it rains for four days because you went in November and nobody told you November is when Lisbon does that. Generic packing lists are no help; they're written for a city, not a date, and "comfortable walking shoes" is advice for literally everywhere on Earth.
The list you want starts with a weather check. So start there.
What to send
Email [email protected] with the destination, the dates, and a sentence about the trip:
"Packing list for Lisbon, November 10 to 17. Two adults, mostly walking around the city, one nicer dinner, maybe a day trip to Sintra. We're carry-on only."
That's enough. If your trip has multiple stops with different climates, even better to say so. "Three days in Reykjavik, then four in Barcelona" is exactly the kind of trip where people end up wearing the wrong coat in both places.
What you get back
Mabel looks up the actual forecast for your dates when it exists, and the historical pattern for that week when you're booking further out, with sources linked. Then the list is built around what she found, not around the postcard version of the place. For that November Lisbon trip, expect something like: highs around 64, rain likely on 3 to 4 of your days, so a packable rain shell beats an umbrella for the hills, shoes with grip because the calçada sidewalks get genuinely slick when wet, and layers over a heavy coat because afternoons still go warm.
The list comes organized so it's usable while you pack: clothing with quantities sized to your trip length and laundry plans, the weather-specific items with a line on why each one made the cut, and a short "worth checking" section for things like plug adapters or whether your day trip needs anything special. Carry-on only? She plans around it: things that layer, things that share duty, and what to leave home.
She'll also flag the stuff a forecast implies but a list never says: sunset at 5:30pm means you want that layer for dinner walks, and "60 percent chance of rain" in some cities means ten gentle minutes, not a washout.
One small upgrade
Tell her what kind of packer you are and who's coming. "I always overpack shoes" or "two kids under 6" or "I run cold" changes the list more than you'd think. And if you're going somewhere for a specific event, a wedding, a conference, a hike with a real trailhead, name it; the difference between trail-day socks and wedding socks is the whole reason packing lists exist.
Forecasts past ten days are educated guesses, and Mabel will say so instead of pretending. But "pack for 60s and rain" beats "pack for the Lisbon in your imagination" every single trip.
