Coatzacoalcos in the Mexican state of Veracruz, has a June average daily high of 40°, and low of 23°, but with 264 mm of rain. Certainly if this is possible in a wet climate so far north, similarly hot weather is possible in a wet climate at the equator, right? And, given less seasonal variation, the city's yearly daily mean would be quite high, no?

We should always keep in mind that Wikipedia is not a good encyclopedia and that unreliable sources are often listed in the pages without any control. Coatzacoalcos' dates are completely wrong; the average daily high for the month of June is around 32°-33° and I believe that also the rainfall data are grossly overestimated. Such a hot summer weather is possible only in desert climates, while in equatorial or tropical wet climates the highest daily highs, no more than 36°-37°, are found right before the wet season in places that experience wet and dry or monsoonal precipitation patterns, like Bangkok, Merida or most of India. These are places which can have a very high annual mean, but still inferior to the cities on the Red Sea coasts.
There are places that can average 40C right before the wet season, such as Kota(42C) and Nagpur (42C) in India, and Ouagadougou (40C) in Burkina Faso. Though the only one of these to average over 27C year-round is Ouagadougou at about 28.75C.

Yes, actually most of central India averages around 40° in the hottest month. But still there are no wet climates near the equator that can average such hot daily highs, with the possible exception of part of Western Australia (where, in fact, there are places with an annual mean close to 30°C).
Allahabad's (Uttar Pradesh) Wikipedia article says with an average high of 40.1, and average low of 28.5, it gets 85.4mm of rain in June. There's enough citations that it must be true. However, I wonder: Is it concentrated in the coolest part of the month where it cools down closer to July's average high of 34.1, or would you still get plenty of rain during the hot part of the month as well?
Looking at a few years on weather underground, June begins hot and bone dry, then it cools off (relatively) and starts raining a lot. There is little to no precipitation at the start or when highs are over 100, (some days have small amounts like 0.1"), then once it cools down it starts to rain a lot. A few years it didn't cool down at all so it had very little rain, others had far above average.
I believe the stats are quite accurate and they resemble those of other cities in the same area, like Port Hedland. It doesn't actually rain with 40°C or 35°C, though. When it rains the temperatures are generally below 30°C and when it doesn't rain the humidity is low and the heat indexes never particularly high. I also believe that the summer rainfalls in those parts of Australia mostly happen in the form of occasional downpours due to erratic cyclones and are not a result of "real" weather fronts.
