4.5 Climate, Seasons & Destination Planning

4.5 Climate, Seasons & Destination Planning

Module 2, Geography in Travel Planning, does not stop at codes and Traffic Conference areas. Once a consultant knows where a place is, the client's next question is always when should I go? This section covers the physical geography that creates seasons, the commercial seasons the trade actually sells, and the hazard windows you are professionally expected to disclose.

The Five Great Circles and Why Seasons Exist

Earth's axis is tilted roughly 23.5 degrees (23 deg 26 min) away from the vertical, and that single fact produces every season on the planet. It also fixes five reference lines of latitude that recur constantly in Foundation questions.

Between the two Tropics the sun passes directly overhead at least once a year, which is why the tropics run on wet and dry seasons rather than four temperature seasons. The equinoxes, around 20 March and 22 September, give roughly equal day and night worldwide.

The Hemisphere Reversal: The Classic Booking Trap

Seasons mirror across the Equator. When it is July in London it is midwinter in Sydney (SYD), Cape Town (CPT) and Buenos Aires (EZE), so a client booking a "summer beach holiday" in Australia for July has bought a winter trip and a consultant who fails to flag it has mis-sold. Read the mirror the other way and it becomes a sales opportunity: the Southern Hemisphere ski season in Queenstown (ZQN) and the Chilean Andes runs roughly June to September, precisely when Alpine and North American resorts are closed.

Climate Zones a Consultant Must Recognise

Tourist Season Is Not the Same as Climatic Season

The trade divides the year into three commercial bands:

• High / peak season - highest demand and rates, minimum-stay rules, blackout dates, thin availability.
• Shoulder season - the weeks either side of peak; usually the best value-to-weather compromise and the band a good consultant sells hardest.
• Low / off season - lowest rates and widest availability, but genuine risk of poor weather, resort and restaurant closures, reduced flight frequencies and suspended excursion programmes.

These bands track demand, not the thermometer. That is why the tourist season and the climatic season frequently disagree:

• Alpine ski resorts: high season is northern winter, roughly December to March, with a Christmas/New Year and February half-term super-peak.
• The Caribbean: high season is northern winter, roughly mid-December to mid-April, driven by North American and European escape demand rather than by local weather.
• The Mediterranean: high season is northern summer, July and August, reinforced by European school holidays.
• East African safari: high season follows the dry season; the Great Migration typically reaches the Masai Mara between July and October (Kenya Wildlife Service), and camps price accordingly.
• The Maldives: high season is northern winter, roughly December to April, the drier north-east monsoon period.

Hazard Windows You Must Disclose

The Harmattan is a dry, dust-laden north-easterly off the Sahara whose haze routinely cuts visibility below one kilometre and causes West African diversions and cancellations. Travel insurance normally stops covering a storm once it has been named, so a client booking into a hurricane window must buy cover and any flexible-fare option at the time of booking, not when a system appears on the forecast map.

Altitude, Acclimatisation and Daylight Extremes

Cusco (CUZ) sits at 3,399 m / 11,152 ft, higher than Machu Picchu itself at 2,430 m. La Paz is served by El Alto (LPB) at 4,061 m, the highest international airport in the world, and Lhasa (LXA) sits at 3,656 m. The UIAA guideline is to raise sleeping altitude by no more than about 500 m per day above 3,000 m, so the professional Peru itinerary lands at CUZ and descends the same day to the Sacred Valley at about 2,850 m for two nights before returning up to Cusco. Note also that the Inca Trail closes every February for maintenance while the citadel itself stays open.

At the other extreme, Nordic itineraries are sold on daylight. Tromso (TOS), north of the Arctic Circle, has midnight sun from about 20 May to 22 July and polar night from 27 November to 15 January; at the North Cape polar night runs about 20 November to 22 January. Aurora clients must therefore be sold into the dark months and never into June.

Holiday Demand Peaks to Overlay

• Golden Week, Japan - 29 April to 6 May 2026; domestic transport and hotels sell out weeks ahead.
• Chinese New Year - 6 February 2027, inside a chunyun travel rush of roughly 40 days; many small businesses close.
• Ramadan and Eid al-Fitr - Ramadan expected to begin about 7-8 February 2027 and Eid around 9-10 March 2027, subject to moon sighting; adjusted opening hours and a sharp Eid travel peak.
• European August - France, Italy and Spain shut down for domestic holidays; city hotels discount while coastal resorts surge.
• Christmas and New Year, and US Thanksgiving - the year's tightest air availability.

Worked Example: Building a Season and Price Table

A honeymoon couple ask for 7 nights in the Maldives (MLE) with a seaplane transfer. They are flexible on dates but have a firm budget. Build the season table before quoting anything.

The index is illustrative and is shown to demonstrate the method; always quote from the live supplier tariff.

Applying it. The couple's first choice was mid-February at index 175. Moving to mid-May puts them in the shoulder band at 120, a reduction of about 31 per cent on the accommodation element, calculated as (175 - 120) / 175. If the resort's low-season rate were USD 400 per night, seven nights would cost roughly USD 3,360 in May against USD 4,900 in February - a saving of about USD 1,540 - while still avoiding the wettest south-west monsoon months. Present both options and state the weather trade-off in writing: that written trade-off is the consultant's protection if the weather disappoints.
