January is a good time to go, with a score of 6.8. Highs reach about 31°C, and rain falls on just 3.1 days on average. You can expect around 10 hours of sun a day, so it suits almost any kind of trip.
33°C / 22°C · 3 rain days · 10.7 h sun
February rates only ok, with a score of 4.3. It is still dry, with 3.2 rain days and 22 mm of rain, but the heat is building and highs reach 33°C. Sun is strong at 10.7 hours a day, so it works if you cope well with heat.
36°C / 25°C · 6 rain days · 10.8 h sun
March is a month to avoid, scoring 2.4. Highs climb to about 36°C, and rain days rise to 5.9. Sun averages 10.8 hours a day. The main problem is the heat, not the rain, and it makes long days of sightseeing hard work.

April is a bad time to go, with a score of just 1.8. It is the hottest month, with highs of 37°C and lows of 26.5°C. Rain days also increase to 8.7, so you get intense heat and some storms together. Avoid it if you can.
