About When Should I Travel

Why we built this

Most travel planning tools optimise for convenience — they show you when flights are cheapest, or when the weather is warmest. Neither of these answers the actual question most travellers have: when should I go to get the best version of this destination?

The answer is almost always shoulder season. Not because it's cheapest — though it usually is. But because shoulder season is when Santorini's sunset is watchable rather than queue-able. When the Amalfi Coast road is driveable rather than gridlocked. When the restaurant you came for takes reservations. When the city, once the summer tourists have gone, becomes itself again.

We built When Should I Travel to make that timing obvious, filterable, and specific — not just "go in September" but exactly which months work for each destination, what the temperatures are, what the hotel prices look like, and what makes each window special.

How we define shoulder season

We define shoulder season as the period when a destination has good-to-excellent conditions for travel but visitor demand — and therefore prices — is meaningfully below peak. In practice this means:

• Weather is still good — not necessarily peak, but within a range suitable for the destination's main draws (beaches, hiking, city exploration, wildlife)
• Key attractions are open — shoulder season is not off-season; restaurants, tours, and seasonal facilities are operating
• Hotel prices are 15–50% below peak — our primary threshold for a true shoulder window
• Visitor volumes allow the experience the destination is known for — a Santorini sunset you can watch, not a Santorini sunset you queue for

Shoulder season timing is destination-specific and doesn't follow a universal calendar. Mediterranean shoulder season (April–May and September–October) is different from East African safari shoulder season (June and October–November), which is different from Japan's (May and October). We research each destination individually rather than applying a blanket definition.

Our data and methodology

Hotel price data

Hotel prices shown are mid-range averages for each destination in shoulder season — representing a comfortable 3–4 star property rather than budget hostels or luxury resorts. Data is sourced from aggregated booking platform pricing across multiple years, with seasonal adjustment to reflect typical shoulder season rates. Prices are indicative and will vary by specific dates, booking lead time, and property type.

Temperature data

Temperature ranges shown are average highs and lows for each month based on 10-year historical climate data for each destination. They represent typical conditions rather than guarantees — weather is variable by nature.

The 37% flight saving figure

The 37% cheaper flights statistic is sourced from KAYAK's published analysis of transatlantic and intra-European flight pricing across peak versus shoulder season periods. It represents an average across European routes; individual routes will vary. Our Shoulder Season Price Report contains full methodology and destination-specific data.

Shoulder season windows

Each destination's shoulder season window is researched individually using a combination of climate data, historical pricing patterns, local knowledge, and published travel industry data. We review and update destination data annually.

Coverage

We currently cover 110 cities across 63 countries on every inhabited continent. Our focus is on destinations with meaningful shoulder season dynamics — places where timing genuinely changes the experience and price. We don't cover every destination in the world, but we aim to cover every destination where the shoulder season argument is strong.

What we're not

We're not a booking platform. We don't sell flights or hotels, and we don't receive commissions from bookings. Our recommendations are based purely on timing analysis — we have no financial incentive to recommend one destination over another.

We're also not a traditional travel guide. We focus specifically on when to visit rather than what to do when you get there. For that, we link to destination-specific city and country guides written with shoulder season timing as the primary lens.
