January travel score: 80/100
Long-run climate normals for Miami, scored with the fixed travel-month weighting below. This is a climatological ranking, not a forecast for a specific year.

September receives 396% more rain than January (253mm vs 51mm), which is the single biggest reason the score gap between them is 40 points.
Daytime highs only move 8°C across the whole year (25–33°C), so timing matters far less here than rainfall does.
June gives you 13.6 hours of daylight against just 10.4 in December — a 3-hour difference in how much you can actually fit into a day.
December is the driest month at 49mm across roughly 4 rain days, while September peaks at 253mm.
February scores 80/100 against 80 for January — only 0 points behind, usually at lower prices and with fewer visitors.
Scores range 40–80/100 across the year, so Miami is a strongly seasonal destination: the wrong month meaningfully degrades the trip.
All twelve months scored 0–100 on the same weighting, so rows are directly comparable both within Miami and against any other destination on Snap Weather.

Every month in Miami is scored 0–100 from climate normals, then ranked against the other eleven. The weighting below is fixed for all cities, so scores are directly comparable between destinations.
| Factor | Weight | What it measures |
|---|---|---|
| Thermal comfort | 45% | Distance from a 23°C daytime ideal, penalised harder on the hot side, with cold nights and humid heat counted separately. |
| Dryness | 30% | Share of days with measurable rain plus total monthly millimetres. |
| Sunshine | 15% | Average daily sunshine hours for the month. |
| Daylight | 10% | Astronomical daylight length at mid-month, calculated from the city’s latitude. |
Figures are long-run climate averages, not a forecast for a specific year. Where a month lacks sourced rainfall or humidity, the value is modelled from temperature range and rain frequency and marked as modelled in the table.
