Frequently asked questions

Which months are highest-ranked for Bangkok?

The highest-ranked months are usually December, January, February. Rankings are computed from long-term climate baselines and historical event-frequency patterns, not short-range forecasts.

What does the monthly score represent?

The monthly score is a 0-100 weather suitability signal for that destination. It is location-relative, so it is designed for comparing months within Bangkok, not for cross-city comparisons.

How are the monthly scores calculated?

Scores combine long-term monthly normals and historical event rates from a 30-year baseline. The model blends Comfort (30%), Rain reliability (25%), Extreme risk (25%), and Outdoor (20%) into a single monthly value.

What do Comfort / Rain reliability / Extreme risk / Outdoor components mean?

Comfort measures typical feel and stability; Rain reliability measures wet-day frequency and rain intensity; Extreme risk captures heat, cold, wind, and related disruption pressure; Outdoor measures day-to-day usability for outdoor plans. Higher values indicate better conditions within each component.

What do "Months ranked by travel style" results mean?

Travel-style rankings reuse the same four components but reweight them for different priorities. In Bangkok, adventure-focused months are often January, December, February, which can differ from the overall order.

What does the "Monthly planning overview" section show?

The Monthly planning overview summarizes month-by-month planning stability and trade-offs. Months are grouped into four bands: Strong window, Mixed, Trade-offs, and Higher disruption.

What does the "Weather risks" panel represent?

This panel summarizes historical weather-event rates for the currently selected month at this location. It is baseline-only and based on a 30-year climate record, not a date-specific forecast.

Do these rankings consider crowds, prices, or events?

No. Rankings on this page are weather-only and based on climate baselines plus historical event patterns.

When should I use Trip Planner instead of this page?

Use this page for month-level baseline comparisons. Use Trip Planner for exact dates because it layers baseline signals with forecast data and threshold-based checks.
