Is Honeydew Melon Acidic or Alkaline?
Honeydew melon (fresh) is alkaline: Negative PRAL: alkalizing after digestion.
Classification
Honeydew melon comes in at −4.4, in the alkaline range, because it brings plenty of potassium per 100 g with hardly any protein. Its sweetness plays no role. That puts it a little less alkaline than cantaloupe but clearly more alkaline than watermelon. A large 250 g piece adds about −11, making it a light dessert with a lot of weight on the alkaline side.
In the Fruit category, honeydew melon (fresh) ranks #32 of 80, sorted from alkaline to acid-forming. More alkaline options include Papaya (−4.5), Fig (−4.7), Passion fruit (−4.7). More acid-forming are Cherimoya (−4.2), Elderberry (−4.1), Nectarine (−4.0).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is honeydew melon acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Honeydew melon (fresh) has a PRAL of −4.4 per 100 g, so it counts as alkaline in your daily acid-base balance.
How much honeydew melon do I need for a noticeable effect?
One piece or a handful (120 g) of honeydew melon adds −5.3 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of honeydew melon roughly offsets one of them.
Why is honeydew melon alkaline even though it tastes sour?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Honeydew melon provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−4.4).
