Hydrogen bonding is very weak, it follows that order of forces:

Ionic bond > Covalent bond > Hydrogen bond > Van der Waals forces. (I have not included electrostatic force for sake of simplicity).

Hydrogen bonds can vary in strength from very weak ($1–2~\mathrm{kJ/mol}$) to extremely strong ($161.5~\mathrm{kJ/mol}$ in the ion $\ce{HF2−}$). Typical enthalpies in vapor include: \begin{array}{cl} \ce{F−H\bond{...}:\!F}& \text{161.5 kJ/mol or 38.6 kcal/mol}\\ \ce{O−H\bond{...}:\!N}& \text{29 kJ/mol or 6.9 kcal/mol}\\ \ce{O−H\bond{...}:\!O}& \text{21 kJ/mol or 5.0 kcal/mol}\\ \ce{N−H\bond{...}:\!N}& \text{13 kJ/mol or 3.1 kcal/mol}\\ \ce{N−H\bond{...}:\!O}& \text{8 kJ/mol or 1.9 kcal/mol}\\ \ce{HO−H\bond{...}:\!OH3+}& \text{18 kJ/mol[15] or 4.3 kcal/mol}\\ \end{array}
