How it tends to feel for travel

In hotter periods, day-versus-night fatigue accumulates differently, changing how the climate feels.

Rainier seasons can feel heavier even at similar temperatures, simply because you spend more time damp or under clouds.

When it tends to fit

  • Once you see the year-round pattern, it’s easier to judge whether a month fits your style.
  • If you revisit the city, separating “seasonal itineraries” can save a lot of planning time.
  • In humidity- or rain-driven cities, adjusting the indoor/outdoor ratio can change comfort a lot.

When it may not fit

  • If you rely only on averages, you may be surprised by variability (squalls, wind, indoor AC).
  • In monsoon-like periods, the more your itinerary depends on outdoor walking, the higher the risk.

Outfit notes

This connects climate patterns to packing—without over-interpreting.

  • 🌬️ Key idea: Haarlem is shaped by wind + frequent light rain. Even when temperatures look moderate, dampness can make it feel suddenly cooler.
  • 🧥 Winter (Dec–Feb): warm coat + layers is the baseline. A windproof/water-resistant rain shell often improves comfort more than just adding thickness.
  • 🌦️ Shoulder seasons (Mar–May, Sep–Nov): quick showers are common—keep a rain option (shell or compact umbrella).

It looks simple on paper, but the day-to-day texture can vary.
