Reading the chart. Gold is good: the month fits what you picked. Any other colour names the reason it doesn't — the temperature bar can be too cold or too hot, the rain bar too dry, too rainy or monsoon. A faded gold bar is a half that fits while the other half fails; a gold month name means both fit.
What the verdicts mean. Temperature is the monthly mean, judged against the preset's band (mean 14–24 °C57–75 °F for Warm). Rain is judged by each month's class within Muscat's own year rather than raw millimetres: dry under 60 mm2.4 in, showers 60–100 mm2.4–3.9 in, rainy from 100 mm3.9 in and 35 % of the wettest month. Too rainy is a rainy-season month the preset doesn't allow. Monsoon is the heaviest kind of rainy season — 180 mm7.1 in or more (120 mm4.7 in near the yearly peak) in a climate whose wettest month is at least three times its driest — so every monsoon month is rainy season too; the label says which kind. Full rules on the method page.
