Reading the chart. Gold means good: the month fits what you picked. Any other colour shows the reason it does not. The temperature bar can be too cold or too hot; the rain bar can be too dry, too rainy or monsoon. A faded gold bar means that half fits but the other half does not. A gold month name means both halves fit.
What the verdicts mean. Temperature is the month's average daily high (the afternoon), judged against the preset's band (highs 19–28 °C66–82 °F for Warm). Rain is judged by each month's class within Algarve's own year, not by raw millimetres: dry under 60 mm2.4 in, showers 60–100 mm2.4–3.9 in, rainy from 100 mm3.9 in and at least 35 % of the wettest month. Too rainy is a rainy-season month that the preset does not 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 where the wettest month has at least three times the rain of the driest. Every monsoon month is also a rainy-season month; the label says which kind. Full rules on the method page.
